...There is a moderate risk (at least 40%) of excessive rainfall for
portions of the Mid-Atlantic...

...Severe weather and excessive rainfall concerns for portions of the
Northern/Central Plains and Upper/Middle Mississippi Valley...

...Major to extreme heat related impacts for portions of the Southwest on
Thursday...

...There is a critical fire weather area for eastern Nevada and far
western Utah...


A slow moving trough and surface front will act as a focus for
afternoon/evening storms across the East Coast over the next couple of
days. Storms are expected to develop and move through the Mid-Atlantic
region tonight, where soils are already relatively saturated. Heavy
rainfall on the order of 2-4 inches in some places may produce flash
flooding, which is why there's a moderate risk of excessive rainfall in
effect for portions of southeastern Pennsylvania down through far
southwestern New Jersey, northern Delaware, central Maryland, DC, the
Virginia Piedmont and north/central North Carolina. Urban areas are
particularly vulnerable due to the ubiquity of impervious surfaces, which
generate runoff when rained on. The Storm Prediction Center issued a
slight risk (level 2/5) of severe thunderstorms across parts of the
Mid-Atlantic and Carolinas. Afternoon/evening storms capable of producing
heavy rainfall are expected to continue across the region through Friday.

Shortwave energy moving through the Great Plains will generate storms
across parts of the Northern/Central Plains and Upper/Middle Mississippi
Valley over the next few days. The Storm Prediction Center issued an
enhanced risk (level 3/5) of severe thunderstorms for portions of central
South Dakota and north-central Nebraska tonight. Severe wind gusts and
isolated large hail are possible. SPC has a separate slight risk area out
for parts of south-central Montana early this evening, with scattered
damaging winds possible. There's a slight risk of excessive rainfall in
effect for portions of Nebraska, South Dakota, Iowa, Minnesota, Wisconsin,
Missouri and Illinois.

A retrograding upper ridge will contribute to above average temperatures
across the West over the next couple of days. Major to isolated extreme
HeatRisk is expected for much of the Southwest through Thursday before
temperatures begin to moderate this coming weekend. Major heat-related
impacts are also possible in and around south Georgia and northern Florida
over the next several days. Elevated thunderstorms over dry soils will
contribute to a critical risk of fires over portions of eastern Nevada and
far western Utah this evening.
