…Severe thunderstorms possible in the Mid-Atlantic and Southeast today…

…Above average temperatures will spread across the West and
north-central U.S. this weekend…

Showers and thunderstorms are forecast to continue today across the
Mid-Atlantic and the Southeast as a slow-moving cold front gradually
pushes towards the East Coast. Severe thunderstorms will be possible from
the eastern Carolinas where the Storm Prediction Center has highlighted an
area with a Slight Risk of Severe Thunderstorms (level 2/5) and in
southern Georgia and north Florida where there is another Slight Risk
(level 2/5) area with an embedded Enhanced Risk (level 3/5) area. The main
thunderstorm threat will be damaging winds, but hail and locally heavy
rainfall/isolated instances of flash flooding will be possible.
Precipitation will come to an end for most areas in these regions tonight
as the front moves into the Atlantic, but isolated showers and storms will
remain possible in south Florida through the weekend as the frontal
boundary slows/stalls.

By this afternoon, a frontal system will develop over the Upper Midwest
then push across the Great Lakes and Ohio Valley tonight. This system will
cause precipitation chances to return to the Mid-Atlantic and southern New
England on Saturday with another round of showers and thunderstorms
expected. This system is forecast to be weaker than the system that
impacted the region on Thursday and Friday, and severe thunderstorms are
not expected. Another front will drop south into the northern Plains and
upper Midwest on Sunday, but the frontal passage is expected to be mostly
dry with only some scattered showers and storms.

Meanwhile, an upper level low and a stationary surface front will be
positioned over the southwestern U.S., which will support low elevation
showers and thunderstorms over the central and southern High Plains and
the Four Corners region and high elevation wintry precipitation through
Saturday. Most lower elevation areas will see light to moderate rainfall,
though some heavier showers/storms will be possible heading into Saturday
evening for portions of west Texas, with some isolated flash flooding
possible. The upper low will gradually push east Saturday night into
Sunday, and precipitation chances will expand into the central and
southern Plains as a low pressure system develops. This system will push
east early next week, and warm, moist inflow from the Gulf of Mexico will
likely support heavy rainfall in the warm sector that could potentially
lead to flash flooding in parts of the South.

The Pacific Northwest and much of California will remain dry through this
weekend as surface high pressure and upper level ridging remain anchored
over the region. This will result in above average temperatures with highs
in the 80s and even lower 90s (15-25 degrees above average) in some areas.
The upper level ridge and above average temperatures will expand east
across the north-central U.S. over the weekend where highs will range from
the mid-70s to the lower 80s. Elsewhere, forecast precipitation and cloud
cover will result in temperatures below or near average.

…There is an Enhanced Risk of severe thunderstorms over parts of the
Southern Plains/Lower Mississippi Valley and the Tennessee
Valley/Southeast on Thursday…

…There is a Slight Risk of excessive rainfall over parts of the Southern
Plains/Lower Mississippi Valley, Tennessee Valley, Southern Appalachians,
and Southeast on Thursday…

…Heavy snow over the higher elevations of the Central Rockies on
Thursday…

On Thursday, a front extending from the Mid-Atlantic westward to the Ohio
Valley and then southwestward to the Southern High Plains will move
eastward off most of the Mid-Atlantic Coast by Friday evening, lingering
over Florida on Saturday.

As the southern half of the boundary moves across the Lower Mississippi
Valley into the Southeast on Friday, it will produce showers and severe
thunderstorms over parts of eastern Texas, Louisiana, central Mississippi,
Southern Alabama, and southern Georgia. The SPC has issued an Enhanced
Risk (level 3/5) of severe thunderstorms over parts of the Southern
Plains/Lower Mississippi Valley and the Tennessee Valley/Southeast through
Friday morning. The potential hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes. There will be the added threat of severe thunderstorm wind
gusts of 65 knots or greater over parts of the Southern Plains to the
Southeast. Moreover, there will be an additional threat of hail two inches
or greater over parts of the Southern Plains.

Furthermore, the showers and thunderstorms will cause heavy rain to
develop over parts of eastern Texas, northern Louisiana, central
Mississippi, Alabama, Georgia, far eastern Tennessee, western North
Carolina, and western South Carolina. Therefore, the WPC has issued a
Slight Risk (level 2/4) of excessive rainfall over the Southern
Plains/Lower Mississippi Valley, Tennessee Valley, Southern Appalachians,
and Southeast 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. Additionally,
showers and severe thunderstorms will develop over parts of the
Mid-Atlantic on Thursday. Moreover, showers and thunderstorms will develop
over parts of the Central Plains and Middle Mississippi Valley. In
addition, moderate to heavy rain will also develop over parts of the
Mid-Atlantic, Ohio Valley, and Middle Mississippi Valley.

On Friday, the remainder of the front will move off most of the Atlantic
Coast, while parts of the boundary will linger over Florida on Saturday.
The system will produce showers and severe thunderstorms over parts of
southern Georgia, extreme southeastern South Carolina, and northeastern
Florida. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the Southeast from Friday into Saturday
morning. The hazards associated with these thunderstorms are frequent
lightning, severe thunderstorm wind gusts, hail, and a few tornadoes.

Moreover, some of the showers and thunderstorms will produce moderate to
heavy rain over parts of southern Georgia, extreme southeastern South
Carolina, and northern Florida. Therefore, the WPC has issued a Marginal
Risk (level 1/4) of excessive rainfall over parts of the Central Gulf
Coast/Southeast from Friday into 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 energy over the Southwest to the Middle Mississippi
Valley will produce rain and higher-elevation snow over parts of the
Northern/Central Rockies from Thursday to Saturday morning. On Thursday,
the system will produce heavy snow over parts of the Central Rockies.

Moreover, overnight Thursday, a weak front moving out of Central Canada
will move into the Upper Mississippi Valley by Friday morning and then
advance eastward to the Great Lakes/Ohio Valley by Saturday. The system
will produce showers and thunderstorms over parts of the Upper Mississippi
Valley Friday afternoon into evening. Overnight Friday, the showers and
thunderstorms move into parts of the Great Lakes and Ohio Valley.
Elsewhere, showers and thunderstorms will develop over parts of the Great
Basin/Southwest and Southern Rockies/Southern High Plains on overnight
Friday. Also, rain will develop over parts of the Northeast and northern
Mid-Atlantic.

A front extending from the Lower Great Lakes on Wednesday will move
eastward off the Northeast Coast overnight Wednesday. In addition, a wave
of low pressure over parts of the Central/Southern Plains will move
eastward to the Ohio Valley by Thursday, and then the northern half of the
boundary will move off the Mid-Atlantic Coast by Friday morning.
Furthermore, a part of the boundary lingers over parts of the Southeast
and Central Gulf Coast also on Friday.

As the wave advances to the Middle Mississippi Valley on Wednesday, it
will bring showers and severe thunderstorms, mainly over parts of southern
Missouri, southern Illinois, western Kentucky, and northwestern Tennessee.
The SPC has issued an Enhanced Risk (level 3/5) of severe thunderstorms
over parts of the Ohio/Tennessee Valleys and Middle Mississippi Valley
through Thursday morning. The potential hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a few tornadoes. There will be the added threat of EF2 to EF5
tornadoes over parts of the Middle Mississippi Valley and the
Ohio/Tennessee Valleys. Moreover, there will be an additional threat of
hail two inches or greater and severe thunderstorm wind gusts of 65 knots
over parts of the Ohio/Tennessee Valleys, Middle/Lower Mississippi Valley,
and Southern Plains.

Furthermore, the showers and thunderstorms will produce heavy rain over
north-central Tennessee and northwestern Kentucky. Therefore, the WPC has
issued a Moderate Risk (level 3/4) of excessive rainfall over parts of the
Ohio/Tennessee Valleys through Thursday morning. The associated heavy
rain will create numerous areas of flash flooding. Furthermore, many
streams may flood, potentially affecting larger rivers. Additionally,
showers and thunderstorms will develop over parts of the Northeast,
Northern Plains, and Upper/Middle Mississippi Valley on Wednesday.

On Thursday, the threat of severe thunderstorms continues from the
Mid-Atlantic to the Southeast and westward to the Southern Plains. The
threat of severe thunderstorms will be the highest over parts of eastern
Texas. Therefore, the SPC has issued an Enhanced Risk (level 3/5) of
severe thunderstorms over parts of the Southern Plains from Thursday
through Friday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes. Moreover, there will be an increased threat of two inches of
hail over eastern Texas.

Further, the showers and thunderstorms will cause heavy rain to develop
over parts of eastern Texas, northern Louisiana, and central Mississippi
Valley. Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over the Southern Plains/Lower Mississippi Valley from
Thursday into 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. Additionally, showers
and thunderstorms will develop over parts of the Central Plains/Middle
Mississippi Valley on Thursday. Moreover, moderate to heavy rain will also
develop over parts of the Northeast, Mid-Atlantic, and Southeast, with a
secondary max over the Great Lakes/Ohio Valley.

Meanwhile, upper-level energy over the Northern Rockies will produce rain
and higher-elevation snow over parts of the Northern/Central Rockies from
Wednesday to Friday. On Wednesday, the system will produce heavy snow over
parts of the Northern Rockies.

…Severe Thunderstorms and Flash Flooding concerns over portions of the
Central/Southern Plains and Mississippi Valley today…

…Cool and snowy in parts of the Northwest with above average and
potentially record breaking temperatures into the Ohio Valley and
Mid-Atlantic on today…

The main area of concern will be across the Central part of the CONUS over
the next couple of days. Shortwave disturbances emerging from the base of
a mid-level trough anchored over the northern tier will generate scattered
to isolated thunderstorms across the Plains and Mississippi Valley today.
Some storms could turn severe, particularly over portions of north-central
Texas, where the Storm Prediction Center issued a Slight Risk (level 2/5)
of Severe Thunderstorms. Thunderstorms over areas that received plenty of
rain recently may cause additional flash flooding concerns, which is why
there’s a targeted Moderate Risk (at least 40%) of Excessive Rainfall over
southeastern Texas. The primary threat of severe weather and excessive
rainfall wanes on Friday as the associated low pressure system and
associated storms move into the Ohio/Tennessee Valley and Lower Great
Lakes regions. A second cold front will sweep through the Great Plains on
Friday, bringing another round of showers and thunderstorms to the region.

An upper trough stationed over the Northwest will generate below average
temperatures across the northern tier today and Friday. This cool airmass
will support high elevation snow across the western mountains, but
particularly over the Northern Rockies, where 6-12 inches of snow are
expected by Saturday morning. A new low pressure system will emerge over
the Pacific Northwest on Friday night, bringing with it enough moisture
for low elevation rain and mountain snow. An upper level ridge downstream
of approaching shortwave impulses will generate well above average
temperatures from the Ohio Valley to the East Coast today and Friday. Some
areas within these regions may tie or break high temperature records
today. There’s a Moderate Heat Risk over portions of the Mid-Atlantic
today affecting individuals who are sensitive to heat, especially those
without effective cooling and/or adequate hydration. Temperatures will
cool down a bit heading into the weekend after a cold front pushes through.
