…Major to locally extreme Heat Risk expected to expand from the Great
Basin into the northern High Plains by Wednesday as well as over portions
of the Central Valley of California…

….Scattered thunderstorms across the southern Plains to the Southeast
today near a stalled front will gradually shift toward the East Coast as
another front will spread additional thunderstorms across the Great Lakes
to New England Tuesday and Wednesday…

…Monsoonal thunderstorms continue across the Great Basin and into the
Four Corners region with threat of localized flash flooding…

A slow-to-evolve summertime weather pattern continues across the U.S.
mainland as we head into late July. This weather pattern will sustain the
ongoing heat wave across the western U.S. while maintaining cooler than
normal temperatures across the mid-section of the country and into
portions of the East Coast. The prolonged nature of the heat in the West
will keep the Heat Risk at major to locally extreme levels across portions
of the Central Valley of California, and the Great Basin today where
another afternoon of triple digit high temperatures is expected.
Meanwhile, a Pacific cold front will set things in motion a bit as the
front moves inland across the Pacific Northwest through the next couple of
days. Triple-digit high temperatures will then expand eastward into
northern High Plains by Wednesday ahead of the front while 110s will
persist across the Desert Southwest and 100s in the Central Valley of
California. Please continue to practice heat safety in this persistent
and prolonged heat wave in the western U.S.

In contrast, cooler than normal temperatures will prevail across the
mid-section of the country and into portions of the eastern U.S. where a
stalled front will keep plenty of clouds along with scattered
thunderstorms. These thunderstorms are not expected to be potent but they
could result in localized flooding issues from time to time across the
southern tier states. The upper-level pattern and instability that
support these thunderstorms from the southern Plains to the Southeast
today will gradually expand northeastward into the eastern U.S. on Tuesday
and then generally affect areas from across the Deep South into much of
the East Coast by Wednesday. Another cold front from eastern Canada will
dip into the northern tier states, bringing additional thunderstorms
across the Great Lakes to New England Tuesday and Wednesday. Meanwhile,
monsoonal thunderstorms will continue across the Great Basin and the Four
Corners region with the threat of localized flash flooding for the next
couple of days.

…A break in the heat continues for much of the eastern two-thirds of the
country but heat will intensify in the interior Pacific Northwest through
this weekend…

…Scattered thunderstorms continue across the South and Southeast as
monsoonal thunderstorms linger across the Four Corners region…

…Scattered thunderstorms over the central Plains today will gradually
shift in the southern Plains by Monday while a cold front will bring new
rounds of thunderstorms across the northern tier states…

A cool air mass settling in across the eastern two-thirds of the country
will offer an extended reprieve from the heat through the next few days.
Afternoon high temperatures will only reach into the 70s and 80s today
from the northern and central Plains eastward through the Atlantic coast
with the exception of the Sunshine State and the coastal plain of Georgia
and South Carolina where highs will remain in the 90s. Texas will have
highs into the 90s to near 100 this afternoon but will cool down into the
70s and 80s by Monday. In contrast, the heat across the western U.S. is
expected to persist, with high temperatures once again exceeding 100
degrees across much of the region. The interior Pacific Northwest will
feel the heat intensify, with afternoon readings possibly reaching 110
degrees at the hottest locations by Sunday afternoon along with little
overnight relief. Daily highs across the Southwest will generally hover
in the 110s. Please continue to practice heat safety in this persistent
and prolonged heat wave in the western U.S. through the next couple of
days. A Pacific cold front will approach the West Coast on Monday,
lowering the heat only slightly for inland sections.

The upper level pattern will be slow to change across the lower 48 through
the next few days. A nearly stationary front will remain draped across the
South and into the Mid-Atlantic region, keeping the cooler air north of
the boundary and the warm, moist air to the south. The front will also
help focusing and triggering scattered thunderstorms from the Gulf Coast
to the Southeast through the next few days. For the Southwest/Four
Corners region, monsoonal moisture will continue to support on-and-off
thunderstorms through the weekend. These storms will keep an elevated
threat for isolated to scattered flash flooding and severe weather, which
may result from the strongest of the storms. Meanwhile, scattered
thunderstorms over the central Plains today will gradually shift into the
southern Plains by Monday as a weak low pressure wave slowly digs
southward. Across the northern tier states, a cold front arriving from
central Canada will bring new rounds of thunderstorms from the northern
Plains through northern New England during the next couple of days.

…A break in the heat is expected for much of the eastern two-thirds of
the country but triple-digit heat will continue in the West through this
weekend…

…Scattered thunderstorms will be confined across the South and Southeast
as monsoonal thunderstorms linger across the Four Corners region…

…Strong to severe thunderstorms possible today over the north-central
Plains…

A cool air mass arriving from central Canada is bringing a welcome relief
to the heat and humidity into the northeastern quadrant of the country
today. Temperatures as high as the 100s a couple of days ago in the
Mid-Atlantic will only recover to around 90 degrees this afternoon with
lower humidity. On the other hand, the heat across the western U.S. is
expected to persist through this weekend, with high temperatures once
again exceeding 100 degrees across much of the region. In fact, the heat
is forecast to intensify over the interior Pacific Northwest, with
readings possibly reaching 110 degrees at the hottest locations by Sunday
afternoon along with little overnight relief. Meanwhile, high
temperatures well into the 110s will be common across the Desert
Southwest. Please continue to practice heat safety in this persistent and
prolonged heat wave in the western U.S. throughout this coming weekend.

The upper-level pattern that supports the heat the West and the cooler
weather across the central to eastern U.S. will be slow to evolve through
the next few days. A front that separates the cool air from the warm and
moist air along the Gulf Coast will remain stationary across the South.
Scattered thunderstorms will be confined in the warm sector across the
South and Southeast where they will linger through the weekend.
Meanwhile, monsoonal moisture will support thunderstorms across the Four
Corners region, lingering on-and-off through the weekend. Isolated to
scattered flash flooding and severe weather may result from the strongest
storms. Farther north, a weak low pressure wave will likely trigger
thunderstorms which could become strong to severe over the north-central
Plains today into tonight. Additional thunderstorms are expected to track
farther east toward Iowa and Missouri during the weekend.

…There is a Slight Risk of severe thunderstorms over parts of the
southern Mid-Atlantic on Thursday…

…There is a Slight Risk of excessive rainfall over parts of the southern
Mid-Atlantic, Southern Plains/Lower Mississippi Valley, and Southern High
Plains/Southern Rockies on Thursday and over the southern Mid-Atlantic and
Southern Rockies on Friday…

…There are Excessive Heat Warnings/Watches and Heat Advisories over
parts of the Pacific Northwest into parts of California/Southwest…

A front extending from Northern New England to the Mid-Atlantic and then
southwestward to the Central Gulf Coast and western Texas will move off
the Northeast and Mid-Atlantic Coast by Friday. Also, the southern half of
the boundary will linger near the Southeast and across the Gulf Coast
States through Friday evening. The lingering boundary will produce
showers and severe thunderstorms over parts of the southern Mid-Atlantic.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the southern Mid-Atlantic through Friday
morning. The hazards associated with these thunderstorms are frequent
lightning, severe thunderstorm wind gusts, hail, and a minimal threat of
tornadoes.

In addition, the showers and thunderstorms will create heavy rain over
parts of the southern Mid-Atlantic. Therefore, the WPC has issued a Slight
Risk (level 2/4) of excessive rainfall over parts of the southern
Mid-Atlantic through Friday morning. The associated heavy rain will
create mainly localized areas of flash flooding, with urban areas, roads,
small streams, and low-lying areas the most vulnerable.

A Second area of heavy rain will develop along the front over parts of the
Southern Plains/Lower Mississippi Valley. Therefore, the WPC has issued a
Slight Risk (level 2/4) of excessive rainfall over parts of the Southern
Plains/Lower Mississippi Valley through Friday morning. The associated
heavy rain will create mainly localized areas of flash flooding, with
urban areas, roads, small streams, and low-lying areas the most
vulnerable. Moreover, tropical moisture and upper-level impulses will
produce showers and thunderstorms over parts of the Gulf Coast to the
Southeast.

Further, a third area of heavy rain will develop over parts of the
Southern High Plains/Southern Rockies. Therefore, the WPC has issued a
Slight Risk (level 2/4) of excessive rainfall over parts of the Southern
High Plains/Southern Rockies through Friday morning. The associated heavy
rain will create mainly localized areas of flash flooding, with urban
areas, roads, small streams, low-lying areas, and burn scars the most
vulnerable.

In addition, moisture over the Southwest and daytime heating will produce
showers and thunderstorms over parts of the Great Basin and Southwest from
the late afternoon into late evening. Additionally, on Thursday,
upper-level impulses going over an upper-level ridge over the Northern
Rockies/Northern High Plains and moisture will produce scattered showers
and thunderstorms over parts of the Northern/Central Rockies.

On Friday, the tropical moisture and nearby boundary will produce showers
and thunderstorms over the Central Gulf Coast to the Southeast and
southern Mid-Atlantic. Some showers and thunderstorms will create heavy
rain over parts of the southern Mid-Atlantic. Therefore, the WPC has
issued a Slight Risk (level 2/4) of excessive rainfall over parts of the
southern Mid-Atlantic from Friday through Saturday morning. The
associated heavy rain will create mainly localized areas of flash
flooding, with urban areas, roads, small streams, and low-lying areas the
most vulnerable.

Furthermore, monsoonal moisture and daytime heating will aid in producing
showers and thunderstorms over parts of the Southwest, Great Basin, and
Central/Southern Rockies from the late afternoon into late evening. An
area of showers and thunderstorms will create heavy rain over parts of the
Southern Rockies/High Plains. Therefore, the WPC has issued a Slight Risk
(level 2/4) of excessive rainfall over parts of the Southern
Rockies/Southern High Plains from Friday through Saturday morning. The
associated heavy rain will create mainly localized areas of flash
flooding, with urban areas, roads, small streams, low-lying areas, and
burn scars the most vulnerable.

Moreover, the upper-level energy moving out of the Northern Rockies into
the Northern/Central Plains will produce showers and strong to severe
thunderstorms with areas of heavy rain. Therefore, the SPC has issued a
Marginal Risk (level 1/5) of severe thunderstorms over parts of the
Northern/Central High Plains from Friday through Saturday morning. The
hazards associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a minimal threat of tornadoes.
Additionally, the WPC has issued a Marginal Risk (level 1/4) of excessive
rainfall over parts of the Northern/Central Plains from Friday through
Saturday morning. The associated heavy rain will create localized areas
of flash flooding, affecting areas that experience rapid runoff with heavy
rain.

Meanwhile, upper-level ridging will build over the Northern Rockies to the
Southwest, spawning Excessive Heat Warnings/Watches and Heat Advisories
over parts of the Pacific Northwest from Thursday into Saturday. Moreover,
the upper-level ridge has prompted Excessive Heat Watches and Heat
Advisories over parts of California and the Southwest. The ridging will
create widespread high temperatures in the 90s to 100s followed by little
overnight relief, with lows in the upper 60s to 70s representing a 20-35
degree departure from average for many areas. The multi-day nature of this
event will create dangerous conditions, particularly for people who are
especially vulnerable to the effects of heat, such as young children,
older adults, people with chronic medical conditions, and pregnant women.

A front extending from the Lower Great Lakes/Ohio Valley across the Middle
Mississippi Valley into the Southern Plains will move slowly off the
Northeast and Mid-Atlantic Coast by Friday. Also, on Friday, the southern
half of the boundary will linger near the Southeast and across the Gulf
Coast States. The boundary will produce showers and severe thunderstorms
over parts of Northern New England to the Mid-Atlantic. Therefore, the SPC
has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of
Northern New England to the Mid-Atlantic through Thursday morning. The
hazards associated with these thunderstorms are frequent lightning, severe

areas of flash flooding, with urban areas, roads, small streams, and
low-lying areas the most vulnerable.

A Second area of heavy rain will develop along the front over parts of the
Southern Plains/Lower Mississippi Valley. Therefore, the WPC has issued a
Slight Risk (level 2/4) of excessive rainfall over parts of the Southern
Plains/Lower Mississippi Valley through Thursday morning. The associated
heavy rain will create mainly localized areas of flash flooding, with
urban areas, roads, small streams, and low-lying areas the most vulnerable.

Moreover, a third area of heavy rain will develop near the boundary over

Southern High Plains/Southern Rockies through Thursday morning. The
associated heavy rain will create mainly localized areas of flash
flooding, with urban areas, roads, small streams, low-lying areas, and
burn scars the most vulnerable.

Furthermore, moisture over the Southwest and daytime heating will produce
showers and thunderstorms over parts of the Great Basin and Southwest late
afternoon into late evening. Additionally, on Wednesday, upper-level
impulses and tropical moisture will produce showers and thunderstorms over
parts of the Southeast.

On Thursday, as the front moves southeastward, showers and strong to
severe thunderstorms will develop over parts of the southern Mid-Atlantic.
Therefore, the SPC has issued a Marginal Risk (level 1/5) of severe
thunderstorms over parts of the over parts of the southern Mid-Atlantic
from Thursday through Friday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts, and
a minimal threat of hail and tornadoes.

The showers and thunderstorms will create heavy rain over parts of the
southern Mid-Atlantic. Therefore, the WPC has issued a Slight Risk (level
2/4) of excessive rainfall over parts of the southern Mid-Atlantic from
Thursday through Friday morning. The associated heavy rain will create
mainly localized areas of flash flooding, with urban areas, roads, small
streams, and low-lying areas the most vulnerable.

A second area of showers and strong to severe thunderstorms will develop
over parts of the Central/Southern High Plains as moisture interacts with
upper-level impulses. Therefore, the SPC has issued a Marginal Risk (level
1/5) of severe thunderstorms over parts of the over parts of the
Central/Southern High Plains from Thursday through Friday morning. The
hazards associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a minimal threat of tornadoes.

Likewise, the showers and thunderstorms will create heavy rain over parts
of the Southern Rockies. Therefore, the WPC has issued a Slight Risk
(level 2/4) of excessive rainfall over parts of the Southern Rockies from
Thursday through Friday morning. The associated heavy rain will create
mainly localized areas of flash flooding, with urban areas, roads, small
streams, low-lying areas, and burn scars the most vulnerable.

Meanwhile, upper-level ridging will build over the Northwest, spawning
Heat Advisories over the region from Wednesday into Friday. Moreover, a
flat upper-level ridge extending from the Lower Mississippi Valley
eastward to the Mid-Atlantic and Southeast will aid in creating a major to
extreme HeatRisk for the East Coast part of the country. The heat has
prompted Excessive Heat Warnings/Watches and Heat Advisories over parts of
the Southern Plains to the Lower Mississippi Valley/Southeast. A second
area of heat has prompted Excessive Heat Warnings/Watches and Heat
Advisories extending from the Mid-Atlantic to parts of New England. On
Wednesday, the near-record temperatures and high humidity suggest Major to
Extreme HeatRisk conditions for portions of the East. Extremely dangerous
and potentially deadly heat, particularly for urban areas in the Southeast
and East Coast, are forecast. Many daily record highs are possible for the
East Coast, and numerous warm overnight lows will provide little relief
from the heat overnight. Heat stress will build rapidly for those without
adequate cooling or hydration. However, a strong cold front will bring
relief as it sweeps across most of the Eastern U.S. from Wednesday into
Thursday. This front will be accompanied by showers and thunderstorms.
Some thunderstorms could be severe, especially in the Northeast.

…There are Excessive Heat Warnings/Watches and Heat Advisories over
parts of the Mid-Atlantic to New England and over parts of
Central/Southern Plains and Middle/Lower Mississippi Valley and parts of
the Western Ohio Valley/Western Tennessee Valley…

A front extending from the Great Lakes across the Middle Mississippi
Valley into the Northern Plains will move to the Lower Great Lakes/Ohio
Valley across the Middle Mississippi Valley and trail off into the
Northern Plains by Wednesday. A wave of low pressure over the Northern
Plains will move northeastward to the Upper Great Lakes by Monday evening,
bringing the cold front northward into the Upper Great Lakes to the Middle
Mississippi Valley/Central Plains. On Monday, the boundary will produce
showers and severe thunderstorms over the Middle Mississippi
Valley/Western Ohio Valley into the Great Lakes. Therefore, the SPC has
issued an Enhanced Risk (level 2/5) of severe thunderstorms over parts of
the Middle Mississippi Valley/Western Ohio Valley through Tuesday morning.
The hazards associated with these thunderstorms are frequent lightning,
severe thunderstorm wind gusts, hail, and a few tornadoes. Moreover, there
is an increased threat of severe thunderstorm wind gusts of 65 knots or
greater, mainly over parts of the Middle Mississippi Valley/Western Ohio
Valley.

In addition, the showers and thunderstorms will create heavy rain over
parts of the Middle Mississippi Valley into the Great Lakes. Therefore,
the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over
parts of the Middle Mississippi Valley into the Great Lakes through
Tuesday morning. The associated heavy rain will create mainly localized
areas of flash flooding, with urban areas, roads, small streams, and
low-lying areas the most vulnerable.

Furthermore, on Monday, upper-level energy and tropical moisture will
produce showers and thunderstorms from parts of the Central Gulf Coast
eastward to the Southeast. Additionally, moisture over the Southwest and
diurnal heating will produce late afternoon into late evening showers and
thunderstorms over parts of the Great Basin, Southwest, and
Central/Southern Rockies.

On Tuesday, the threat of severe thunderstorms reduces slightly. As the
front moves eastward, showers and severe thunderstorms will develop over
parts of the Eastern Ohio Valley, Lower Great Lakes, and Northeast.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the over parts of the Eastern Ohio
Valley/Lower Great Lakes/Northeast from Tuesday through Wednesday morning.
The hazards associated with these thunderstorms are frequent lightning,
severe thunderstorm wind gusts, hail, and a few tornadoes.

Furthermore, showers and thunderstorms will produce heavy rain over parts
of the Middle Mississippi Valley to Ohio Valley. Therefore, the WPC has
issued a Slight Risk (level 2/4) of excessive rainfall over parts of the
Middle Mississippi Valley to Ohio Valley from Tuesday through Wednesday
morning. The associated heavy rain will create mainly localized areas of
flash flooding, with urban areas, roads, small streams, and low-lying
areas the most vulnerable.

Moreover, as the western end of the front moves across the Central High
Plains, showers and severe thunderstorms will develop over the region.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the over parts of the Central High Plains from
Tuesday through Wednesday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a minimal threat of tornadoes.

Also, upper-level energy and tropical moisture will produce showers and
thunderstorms over parts of the Southeast. Further, moisture over the
Southwest and the Central/Southern Rockies, along with diurnal heating,
will produce late afternoon into late evening showers and thunderstorms
over parts of the Great Basin, Southwest, and Central/Southern Rockies.

Meanwhile, a flat upper-level ridge extending from the Four Corners Region
eastward to the Mid-Atlantic and Southeast will aid in creating a major to
extreme HeatRisk for the East part of the country. The developing heat has
prompted Excessive Heat Warnings/Watches and Heat Advisories over parts of
the Mid-Atlantic to New England and over parts of the Central/Southern
Plains and Middle/Lower Mississippi Valley and parts of the Western Ohio
Valley/Western Tennessee Valley. The near-record temperatures and high
humidity suggest Major to Extreme HeatRisk conditions for portions of the
East, Monday and Tuesday. Extremely dangerous and potentially deadly heat,
particularly for urban areas in the Southeast and East Coast, are forecast
for Monday and Tuesday. Many daily record highs are possible for the East
Coast, and numerous warm overnight lows will provide little relief from
the heat overnight. Heat stress will build rapidly for those without
adequate cooling or hydration.

….There is a Slight Risk of severe thunderstorms over parts of the
Northern Plains into the Upper Mississippi Valley on Sunday and the
Upper/Middle Mississippi Valley into the Great Lakes on Monday…

…There is a Slight Risk of excessive rainfall over parts of Middle
Mississippi Valley into the Great Lakes on Monday…

…Dangerous and record-breaking heat begins to build across the Central
Plains, Mid-Atlantic, and Southeast…

A front extending from the Upper Mississippi Valley/Upper Great Lakes to
the Northern Plains will move to the Great Lakes/Middle Mississippi Valley
and trail off into the Northern High Plains by Monday. A wave of low
pressure over the Northern Plains will move northeastward into Ontario,
Canada, by Tuesday, bringing the cold front into the Great Lakes to the
Middle Mississippi Valley/Central Plains. The boundary will produce
showers and severe thunderstorms over the Northern Plains/Upper
Mississippi Valley on Sunday. Therefore, the SPC has issued a Slight Risk
(level 2/5) of severe thunderstorms over parts of the Northern
Plains/Upper Mississippi Valley through Monday morning. The hazards
associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a few tornadoes. Further, there is an
increased threat of severe thunderstorm wind gusts of 65 knots and hail
two inches or greater, mainly over parts of the Northern Plains.

Also, showers and thunderstorms will develop over parts of the Great Lakes
into parts of the Mid-Atlantic. Furthermore, upper-level energy and
tropical moisture will produce showers and thunderstorms from parts of the
Western Gulf Coast eastward to the Southeast. Additionally, moisture over
the Southwest and diurnal heating will produce late afternoon into late
evening showers and thunderstorms over parts of the Great Basin,
Southwest, and Central/Southern Rockies.

On Monday, a wave of low pressure along the front over the Upper Midwest
will pull the front back over parts of the Great Lakes, creating showers
and severe thunderstorms in some parts of the area. Therefore, the SPC has
issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the
Upper/Middle Mississippi Valley into the Great Lakes from Monday through
Tuesday morning. The hazards associated with these thunderstorms are
frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes.

Moreover, the showers and thunderstorms will produce heavy rain over parts
of the Middle Mississippi Valley into the Great Lakes. Therefore, the WPC
has issued a Slight Risk (level 2/4) of excessive rainfall over parts of
the Middle Mississippi Valley into the Great Lakes from Monday into
Tuesday morning. The associated heavy rain will create mainly localized
areas of flash flooding, with urban areas, roads, small streams, and
low-lying areas the most vulnerable.

Also, upper-level impulses will create showers and thunderstorms over
parts of the Lower Great Lakes into parts of the Mid-Atlantic.
Furthermore, upper-level energy and tropical moisture will produce showers
and thunderstorms from parts of the Southeast.

Meanwhile, an upper-level subtropical high over the Great Basin/Southwest
into the Central/Southern Rockies will weaken, allowing heat to expand
over portions of the central and eastern U.S. on Sunday into Tuesday.
Confidence is increasing in extremely dangerous, potentially deadly heat,
particularly for urban areas in the Southeast and East Coast beginning
Monday. Many daily record highs are possible for the East Coast, and
numerous warm overnight lows will provide little relief from the heat
overnight. Heat stress will build rapidly for those without adequate
cooling or hydration.

…There is a Slight Risk of severe thunderstorms over parts of the
Northern Plains into Upper Mississippi Valley on Saturday and Sunday…

…There is a Slight Risk of excessive rainfall over parts of northern
Mid-Atlantic on Saturday…

…Dangerous and record-breaking heat will continue for much of the West
through Saturday, while sizzling temperatures will also begin to build
across the Central Plains and Southeast...

A weak front with tropical moisture will be quasi-stationary over parts of
the Northeast, Mid-Atlantic, and Southeast through Sunday morning. Showers
and thunderstorms will develop along and near the boundary as the tropical
moisture produces heavy rain over parts of the Easter Seaboard. Therefore,
the WPC has issued a Slight Risk (level 2/4) of excessive rainfall with
these thunderstorms over parts of the northern Mid-Atlantic through Sunday
morning. The associated heavy rain will create mainly localized areas of
flash flooding, with urban areas, roads, small streams, and low-lying
areas the most vulnerable.

In addition, on Saturday, a front over the Northern Plains will move
across the Northern Plains into the Upper Mississippi Valley and extending
into the Upper Great Lakes by Monday. The boundary will produce showers
and severe thunderstorms over the region. Therefore, the SPC has issued a
Slight Risk (level 2/5) of severe thunderstorms over parts of the Northern
Plains into Upper Mississippi Valley through Sunday morning. The hazards
associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a few tornadoes. Further, there is an
increased threat of severe thunderstorm wind gusts of 65 knots and hail
two inches or greater over parts of the Northern High Plains.

Moreover, upper-level energy and tropical moisture over the Western and
Central Gulf Coast will produce showers and thunderstorms. Furthermore,
moisture streaming northward from the Gulf of California and weak
upper-level energy will aid in producing scattered showers and
thunderstorms over parts of Southern California and Southwest.

On Sunday, a wave of low pressure along the front over the Upper Midwest
will move from Montana to North Dakota, creating showers and severe
thunderstorms in parts of the area. Therefore, the SPC has issued a Slight
Risk (level 2/5) of severe thunderstorms over parts of the Northern Plains
into Upper Mississippi Valley from Sunday through Monday morning. The
hazards associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, hail, and a few tornadoes. Also, showers and
thunderstorms will develop over parts of the Great Lakes into parts of the
Mid-Atlantic. Furthermore, upper-level energy and tropical moisture will
produce showers and thunderstorms from parts of the Western Gulf Coast
eastward to the Southeast. Moisture over the Southwest and diurnal heating
will produce late afternoon into late evening showers and thunderstorms
over parts of the Great Basin, Southwest, and Central/Southern Rockies.

Meanwhile, an upper-level subtropical high over the Great Basin/Southwest
into the Central/Southern Rockies will allow an extremely dangerous heat
wave to persist over the area. The upper-level ridging will produce a near
all-time high temperature record, and heat will continue over portions of
the Southwest through Sunday. This long-duration heat wave remains
extremely dangerous and deadly if not taken seriously. Dozens of daily
record high temperatures are forecast over much of the West through
Sunday. Hazardous heat will expand in coverage over portions of the Middle
Mississippi Valley and Southeast on Sunday and Monday.

…There is a Slight Risk of severe thunderstorms over parts of the
Northern Plains into Upper Mississippi Valley on Saturday…

…There is a Slight Risk of excessive rainfall over parts of the
Mid-Atlantic into the Northeast on Friday and a Slight Risk over Southern
New England on Saturday…

…Dangerous and record-breaking heat will continue for much of the West

across the Central Plains and Southeast…

A weak front with tropical moisture will be quasi-stationary over parts of
the Northeast, Mid-Atlantic, and Southeast through Sunday. Showers and
thunderstorms will develop along and near the boundary as the tropical
moisture produces heavy rain over parts of the Easter Seaboard. Therefore,
the WPC has issued a Slight Risk (level 2/4) of excessive rainfall with
these thunderstorms over parts of the Mid-Atlantic into the Northeast
through Saturday morning. The associated heavy rain will create mainly
localized areas of flash flooding, with urban areas, roads, small streams,
and low-lying areas the most vulnerable.

In addition, on Friday, weak upper-level energy and a nearby front will
help produce showers and thunderstorms over parts of the Upper Midwest and
Great Lakes. Likewise, upper-level energy over the Western and Central
Gulf Coast will produce showers and thunderstorms.

On Saturday, the weak front will dissipate over the Southeast while
tropical moisture will aid in producing showers and thunderstorms with
heavy rain over parts of Southern New England. Therefore, the WPC has
issued a Slight Risk (level 2/4) of excessive rainfall with these
thunderstorms over parts of Southern New England from Saturday through
Sunday morning. The associated heavy rain will create mainly localized
areas of flash flooding, with urban areas, roads, small streams, and
low-lying areas the most vulnerable.

Also, on Saturday, a front over the Northern High Plains will move across
the Northern Plains into the Upper Mississippi Valley. The boundary will
produce showers and severe thunderstorms over the region. Therefore, the
SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over
parts of the Northern Plains into Upper Mississippi Valley from Saturday
through Sunday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes. Furthermore, showers and thunderstorms will develop over parts
of Texas on Saturday.

Meanwhile, an upper-level subtropical high over Central/Southern
California into the Southwest and parts of the Great Basin will allow an
extremely dangerous heat wave to persist over the area. The upper-level
ridging will produce a near all-time high temperature record, and heat
will continue over portions of the Southwest through Saturday. This
long-duration heat wave remains extremely dangerous and deadly if not
taken seriously. Dozens of daily record high temperatures are forecast
over much of the West through Saturday. Hazardous heat will expand in
coverage over portions of the central and eastern U.S. late this weekend.
Moreover, moisture over the Southwest will produce scattered showers and
thunderstorms on Saturday.
