...Isolated to scattered severe thunderstorms and heavy rain in the
Central and Southern Plains today...

...Heavy snow possible in the high elevations of Wyoming today and the
Sierra Nevada on Saturday...

A slow-moving frontal boundary is expected to move southeast across the
Central and Eastern U.S. over the next couple days and will be the focus
for daily thunderstorm activity through Saturday. Today, the frontal
boundary will stretch from the Great Lakes to the Central Plains with a
dry line likely extending to the south across western Texas. The
environment will be favorable for strong to severe thunderstorm to develop
today in the Central and Southern Plains, with warm moist air in place
while an upper level shortwave moves east across the region. Isolated
strong to severe thunderstorms are expected to develop, and severe storm
hazards could include large hail and strong wind gusts. Additionally,
thunderstorms are expected to produce heavy rain, which may lead to
isolated to scattered instances of flash flooding. Thunderstorms will also
be possible across the Southeast today along a dying stationary boundary.

The frontal boundary will gain more momentum as low pressure consolidates
and deepens near the Great Lakes on Friday. The boundary is expected to
push into the Mississippi and Ohio Valleys on Friday and the Northeast,
Mid-Atlantic, and Southeast on Saturday. Shower and thunderstorm chances
will move with the boundary, and there will be a continued chance for
isolated strong to severe thunderstorms in the Southern Plains where the
tail end of the front will become stationary. A portion of the front will
also remain stationary up against the Rockies, which should support
continued precipitation chances through Friday, with heavy snow possible
in the higher elevations of Wyoming today.

Meanwhile, a deep upper level low is forecast to approach the West Coast
and bring a cold front towards the California coast on Saturday. Pacific
moisture will spread into the West, increasing precipitation chances
Friday and Saturday. Widespread rain and high elevation snow are expected,
and snow may be heavy in the Sierra Nevada on Saturday.

Temperatures will generally be above average for areas of the Central and
Eastern U.S. on the southern side of the frontal boundary today and
Friday, with highs in the 70s and 80s, while areas on the northern side
are a bit cooler. Below normal temperatures should spread south and east
as the front progresses, and below normal temperatures will also develop
along the West Coast under the deep upper low.
