…There is a Slight Risk of severe thunderstorms over parts of the
Southern Plains on Tuesday and over parts of the Upper Mississippi Valley
on Wednesday…

…There is a Slight Risk of excessive rainfall over parts of the southern
tip of Florida through Wednesday…

…There are Excessive Heat Warnings/Watches and Heat Advisories over
Northern/Central California, Southwest, and western Texas on Tuesday…

A front extending from the Southeast across the Gulf Coast into the
Southern Plains will make the eastern portion quasi-stationary over the
Southeast. At the same time, the western half dissipates on Wednesday. The
half of the west of the boundary will aid in creating showers and severe
thunderstorms over parts of south-central Texas. Therefore, the SPC has
issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the
Southern Plains through Wednesday morning. The hazards associated with
these thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a minimal threat of tornadoes.

Furthermore, showers and thunderstorms will develop along the eastern
portion of the front. The combination of tropical moisture and upper-level
impulses will aid in producing showers and thunderstorms with heavy rain
over parts of southern Florida. Therefore, the WPC has issued a Slight
Risk (level 2/4) of excessive rainfall on 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. Also, showers and thunderstorms will develop along parts
of the Mid-Atlantic Coast.

In addition, the tropical moisture will continue to produce showers and
thunderstorms with heavy rain over parts of southern Florida. Therefore,
the WPC has issued a Slight Risk (level 2/4) of excessive rainfall from
Wednesday into 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.

Meanwhile, an upper-level low over the Northeast will help develop rain
with daytime-embedded thunderstorms over the area on Tuesday and Wednesday.

Elsewhere, another front over the Upper Mississippi Valley extending
southwestward to the Central Rockies/Great Basin will move eastward to the
Great Lakes and dissipate by Wednesday evening. On Tuesday, the front will
produce showers and thunderstorms over parts of the Upper Mississippi
Valley/Upper Great Lakes into the Central Plains and Central Rockies.

On Wednesday, moisture pooling along the boundary will create showers and
severe thunderstorms over parts of the Upper Mississippi Valley.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the Upper Mississippi Valley from Wednesday
through Thursday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes. Moreover, there will be an added threat of hail, two inches or
greater, over the region. Further, showers and thunderstorms will develop
from the Gulf Coast to the Southern High Plains on Wednesday.

Furthermore, upper-level ridging will build over California and the
Southwest on Tuesday, and a subtropical high will develop over
North-Central Mexico, prompting Excessive Heat Warnings and Advisories
over Northern/Central California and Southwest and Excessive Heat Watches
in western Texas. Residents and individuals involved in outdoor activities
must stay informed and take necessary precautions.

A front over the Northern Rockies to the Great Basin will move eastward to
the Upper Great Lakes/Upper Mississippi Valley by Wednesday afternoon. As
moisture streams northward into the Northern Rockies/Northern Plains, the
boundary will produce showers and severe thunderstorms over parts of
western South Dakota, northwestern Nebraska, eastern Wyoming, and extreme
eastern Montana. Therefore, the SPC has issued a Slight Risk (level 2/5)
of severe thunderstorms over parts of the Northern/Central High Plains
through Tuesday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes.

Further, a front extending from the Southeast to the Southern Plains will
trigger showers and severe thunderstorms over parts of southeastern
Georgia and southern South Carolina. Therefore, the SPC has issued a
Slight Risk (level 2/5) of severe thunderstorms over parts of the
Southeast through Tuesday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes. Showers and thunderstorms will also develop
over parts of the Central/Southern Rockies and Southern Plains on Monday.
In addition, upper-level energy over the Great Lakes/Northeast will help
produce rain and showers/thunderstorms over parts of the Lower Great
Lakes, Northeast, Central Appalachians, and northern Mid-Atlantic through
Monday night.

On Tuesday, showers and thunderstorms will develop over parts of the
Upper/Middle Mississippi Valley/Upper Great Lakes, Central/Southern
Rockies, and Central/Southern Plains.

Furthermore, the combination of tropical moisture and upper-level impulses
will aid in producing showers and thunderstorms with heavy rain over parts
of southern Florida. This weather pattern has led the WPC to issue a
Slight Risk (level 2/4) of excessive rainfall 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.

Elsewhere, a front over the Eastern Pacific will move onshore over the
Pacific Northwest and advance eastward to the Northern Plains to the Great
Basin by Wednesday. The system will produce rain over parts of the
Northwest and scattered showers and thunderstorms over parts of the
Northern High Plains on Wednesday. Furthermore, upper-level ridging will
build over California and the Southwest on Tuesday prompting Excessive
Heat Warnings/Watches and Heat Advisories over Northern/Central California
and Southwest. It’s crucial for residents and individuals involved in
outdoor activities to stay informed and take necessary precautions.

A front extending from the Mid-Atlantic southwestward to the Tennessee
Valley and then westward to the Central Rockies will move eastward to off
most of the Eastern Seaboard by Monday evening. Moisture pooling along the
boundary will aid in creating showers and thunderstorms with heavy rain
over southern Missouri. Therefore, the WPC has issued a Moderate Risk
(level 3/4) of excessive rainfall over parts of the Middle Mississippi
Valley through Monday morning. The associated heavy rain will create
numerous areas of flash flooding. Furthermore, many streams may flood,
potentially affecting larger rivers.

Moreover, showers and strong to severe thunderstorms will develop along
the front from the Southeast to the Northern Intermountain Region.
Therefore, the SPC has issued a Marginal Risk (level 1/5) of severe
thunderstorms over parts of the Southeast, Tennessee Valley, lower
Mississippi Valley, Southern Plains, Central Rockies, and the Northern
Intermountain Region through Monday morning. The hazards associated with
these thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a minimal threat of tornadoes.

Meanwhile, a front over the Eastern Pacific will move inland to the
Pacific Northwest/Central California by early Sunday afternoon. On Sunday,
the boundary will produce showers and thunderstorms over parts of the
Pacific Northwest and Northern Intermountain Region. The front will
continue to move eastward to the Northern Plains by Monday. The front will
trigger showers and severe thunderstorms over parts of western South
Dakota, northwestern Nebraska, and extreme eastern Montana/Wyoming.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the Northern/Central High Plains from Monday
through Tuesday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few

…Threats for severe weather and flash flooding for portions of the
Central Plains into the middle/lower Missouri River Valley through
Saturday…

…Excessive heat over the West and Southwest through Saturday but some
relief coming on Sunday…

Most of the active weather across the lower 48 will focus across the
central portion of the nation through the weekend in the form of severe
thunderstorms and potential for flash flooding. Anomalous moisture will
pool in the vicinity of a pair of frontal boundaries located over the
Central Plains this evening. Severe thunderstorms are expected to increase
in coverage through this evening near a stationary front currently in
place across Nebraska, with threats for large hail and damaging straight
line winds in addition to tornadoes. An organized thunderstorm complex is
likely to form tonight and translate toward the southeast toward the lower
Missouri Valley, carrying a risk for flash flooding with high rainfall
rates and possibly 4-5 inches of rain by Saturday morning.

Severe weather (mainly hail and wind) and flash flood potential will focus
a little farther south on Saturday as a cold front moves through the
central Plains. The threat region will extend from the central High
Plains, through southern KS into the middle Mississippi and lower Ohio
Valleys. Spotty rainfall totals in excess of 3 inches will be possible in
addition to the severe thunderstorms.

Out West, an upper level ridge in place over the western U.S. will
maintain the hot weather on Saturday that has been impacting the region
over the past couple of days. However, the upper level ridge will be
displaced and weakened with the approach of an upstream trough axis and
associated surface cold front. The cold front is forecast to arrive early
on Sunday and advance south and east during the day which will lower the
magnitude of hot weather. Temperatures however, are still likely to remain
up to roughly 10 degrees above average on Sunday.

Across the Great Lakes region into the Northeast, temperatures will run 5
to 15 degrees below average beneath the influence of upper level troughing
this weekend. The region will remain unsettled however, with multiple
rounds of showers and thunderstorms beneath the upper trough and with a
surface low/cold front tracking eastward through Sunday. East of the
Appalachians, from the Mid-Atlantic to Southeast, high pressure will keep
temperatures near to slightly above average for the weekend but with
little to no chances for precipitation. The one exception will be across
the Florida Peninsula where high temperatures in the middle to upper 90s
may challenge a few daily maximum temperature records on Saturday and
Sunday. In addition, diurnally driven thunderstorms are expected each day
but with a focus across southern Florida where access to better moisture
will reside.

…Excessive Heat Warnings in effect across parts of California’s Central
Valley region as well as the Desert Southwest; Extreme Heat Risk continues
across south Texas…

…Thunderstorms and heavy to Excessive Rainfall possible from Southern
Plains to Northeast through Thursday…

A very pronounced ridge will build across the Western U.S. over the next
few days while upper-level lows influence the pattern across the lower 48
from their respective stations off the Baja and Nova Scotia Coasts. The
upper ridge will support a heat wave which will expand across the region.
High temperatures in the 90s and 100s will be 20-30 degrees above average
for this time of year, while low temperatures in the upper 60s and 70s
will offer little respite at night. Widespread high and low temperature
records may be tied or broken through Friday. There are Excessive Heat
Warnings in effect for California’s Central Valley as well as portions of
the Desert Southwest including southeastern California, southern Nevada
and western/southern Arizona. Mild night time temperatures will continue
to plague southern Texas through the end of the week. These extremely hot
conditions will affect anyone without effective cooling and/or adequate
hydration.

A pair of low pressure systems tracking across the eastern half of the
country will trigger scattered to isolated showers and thunderstorms
across much of the region today before shifting into just the East Coast
on Thursday. Deep layer moisture paired with instability will support
locally heavy rainfall over parts of the Ohio Valley, Central Appalachians
and Mid-Atlantic where a Slight Risk (at least 15%) of Excessive Rainfall
leading to Flash Flooding is in effect for today. The threat for Excessive
Rainfall shifts into parts of the interior Northeast and New England on
Thursday, where another Slight Risk of Excessive Rainfall is in effect. A
pattern change will ensue across the Eastern U.S. on Thursday, in which a
digging trough will usher in cooler air temperatures and continue through
the weekend.

…There is a Moderate Risk of Excessive Rainfall leading to Flash
Flooding over parts of southeastern Oklahoma and the ArkLaTex today…

…Severe Thunderstorms possible across parts of the Mississippi Valley
today…

…Growing Excessive Heat potential over portions of California’s central
valley region as well as the Desert Southwest; southern Texas heat risk
persists…

An amplified upper trough will swing through the Great Plains and
Mississippi Valley, bringing with it a pair of cold fronts and
thunderstorm activity over the next couple of days. Potent mid-level
energy on the southern periphery of the trough anchored over
southern-central Canada will move slowly across the Deep South today and
promote a pair of MCSs to propagate across the ArkLaTex region this
morning and then again tonight. The repeating thunderstorms (potentially
severe) over the same area prompted the issuance of a Moderate Risk (at
least 40%) of Excessive Rainfall leading to Flash Flooding over portions
of southeastern Oklahoma through the ArkLaTex for the 24 hour period
ending Wednesday morning. Frontally driven diurnal convection will also
occur across the Upper/Middle Mississippi Valley this afternoon and
evening. The Storm Prediction Center issued Slight Risks (level 2/5) of
Severe Thunderstorms over parts of the Upper/Middle Mississippi Valley and
another one across the ArkLaTex into western Mississippi. Large hail and
severe wind gusts will be the main threat for any severe storms that
develop over the Upper/Middle Mississippi Valley, while damaging wind
gusts will be the sole threat across the ArkLaTex/Lower Mississippi Valley.

A deepening upper ridge in the West and cutoff low west of Baja will
support a heat wave across much of the Western U.S. over the next several
days. Temperatures will be below average for the Pacific Northwest today
but will be overtaken by warmer conditions beginning on Wednesday. Areas
of particular concern include the low elevation regions of California’s
central valley and the Desert Southwest where high temperatures will
easily climb over 100 degrees beginning today. High temperature anomalies
of 20-30 degrees above average are likely. Widespread temperature records
are expected to be tied or broken across much of the aforementioned areas.
Excessive Heat Warnings and Watches extend from the central valley down
through southern California’s deserts, southern Nevada and
southern/western Arizona. HeatRisk will peak over California’s central
valley on Wednesday before expanding into the Desert Southwest later this
week. Little overnight relief will make for dangerous conditions for those
without effective cooling and/or adequate hydration. HeatRisk over
southern Texas peaks today but persists for the next few days.

…Excessive Rainfall and Severe Weather threaten portions of the
Mississippi Valley and Southern Plains today…

…Increasing Excessive Heat Risk potential over parts of the West and
southern Texas through mid-week…

Shortwave energy spinning through the Northwest will support showers and
thunderstorm activity across the region today. Rainfall rates over the
favored terrain of the Cascades and Northern Rockies will be high enough
to warrant an Excessive Rainfall threat. Thus, a Slight Risk (at least
15%) of Excessive Rainfall leading to Flash Flooding is in effect for
portions of the Northern Rockies, while a Marginal Risk (at least 5%) area
is in place over the Cascades, Olympics and Seattle Metro area. Elsewhere,
showers and thunderstorms are expected to continue over parts of the Great
Plains and Mississippi Valley today. Pockets of severe thunderstorms
capable of producing heavy to excessive rainfall may develop over parts of
the Southern Plains into the Mississippi Valley. Slight Risks of Excessive
Rainfall and Severe Thunderstorms are in effect over those areas, where a
swath of damaging wind gusts are possible. The severe thunderstorm threat
concentrates over parts of the Central Plains and Middle Mississippi
Valley on Tuesday, where a Slight Risk is in effect. Large hail is
possible at the outset when storms are more cellular, but will then be
followed by a congealing of cells into a line of storms with damaging wind
gusts eventually being the main threat.

An upper ridge is expected to develop over the West early to mid-week.
High temperatures will gradually climb into 100s by Wednesday and Thursday
with many records potentially being tied or broken on those days.
Excessive Heat Warnings are in effect for the central valley region of
California while Excessive Heat Watches are in effect for parts of the
Desert Southwest. Extreme HeatRisk is probable to continue for much of
southern Texas through Wednesday. This level of heat risk means that there
will likely be little to no overnight relief for those without effective
cooling and/or adequate hydration.

…Excessive Rainfall and Severe Thunderstorms possible over portions of
the Great Plains and Mississippi Valley…

…Heavy to Excessive Rainfall possible across parts of the Northwest
through Monday…

…Increasing Excessive Heat threat over parts of California, Nevada and
Arizona…

A series of shortwaves will be responsible for Excessive Rainfall and
Severe Thunderstorms that develop across the Great Plains and Mississippi
Valley over the next few days. Today, showers and isolated thunderstorms
will spread from the High Plains into the Mississippi Valley. Some storms
may turn severe. The Storm Prediction Center issued an Enhanced Risk
(level 3/5) of Severe Thunderstorms across portions of the Central High
Plains this afternoon and evening. Very large hail, severe wind gusts
greater than 75 mph, and a few tornadoes are expected. Rain rates in some
of those storms could be high enough to cause flash flooding which is why
there’s a Slight Risk (at least 15%) of Excessive Rainfall over parts of
the Northern/Central Plains and Upper/Middle Mississippi Valley.

Elsewhere, a deep upper low will transport anomalous tropical Pacific
moisture into the Northwest today. Excessive Rainfall is naturally a
concern over the favorable terrain of the Cascades, Bitterrroots, Salmon
River Mountains as well as the Seattle metro, where Slight Risks (at least
15%) are in effect through Monday. Monday will be a Marginal Risk kind of
day for Excessive Rainfall and Severe Thunderstorms over parts of the
Southern/Central Plains and Mississippi Valley. Cloudy/cooler conditions
will prevail over the Northwest thanks to the Atmospheric River event set
to unfold over the next couple of days. Otherwise, the Great Plains and
Northeast are likely to experience above average temperatures this week.
Abnormal heat is expected to expand across parts of the West mid-week.
