...A lessening threat for severe weather and flash flooding will continue
into the Southeast on Wednesday...

...Snow and ice accumulations will continue into Wednesday for northern
parts of the Great Lakes...

...Critical fire weather threat for parts of Texas, with record heat
through this week across the West...


The same storm system which brought widespread severe weather and heavy
rainfall the past couple of days across the Deep South will continue into
the Eastern U.S. today, although the severe and flash flood threat should
wane somewhat as the environment becomes less favorable. Even still, heavy
rainfall is possible along the front across the Southeast and Mid-Atlantic
today, with WPC highlighting this with a marginal to slight risk for
excessive rain/flash flooding. SPC also has a slight risk for severe
thunderstorms across much of the Southeast, as well as farther north and
west into parts of the Ohio Valley. Rainfall will also expand across the
Midwest and into the Northeast with modest snow and ice accumulations
continuing on Wednesday for parts of the northern Great Lakes. Rain should
exit the East Coast with the front by Thursday, though may linger across
the Northeast/New England as a secondary low forms and lifts up the coast.
Some wintry weather is likely in the highest elevations of New England. In
the wake of this expansive system, a colder air mass should settle in,
with below normal temperatures spreading from the Plains on Wednesday into
the Midwest/Ohio Valley Thursday and Friday.

Elsewhere, gusty winds and dry conditions will continue an elevated to
critical fire weather threat across western to central/southern Texas
through Thursday. A weak front into the West will bring some light rain
and mountain snow to parts of the Pacific Northwest, but there shouldn't
be much precipitation to accompany the front as it moves east into the
interior West and northern Plains. Some rain or wintry weather may develop
with the front into the Upper Great Lakes on Friday, with another period
of gusty winds possible.

A strong and expansive upper level ridge parked over the Western U.S. will
bring much above normal temperatures to much of the western half of the
country through at least the remainder of the work week. Daytime highs for
parts of California and the Great Basin could be 10 to 20 degrees above
normal. Numerous record high temperatures are possible.
