Ongoing heavy rainfall and strong to severe thunderstorms across the Lower
Mississippi Valley this morning will continue drifting slowly eastward
today (Thursday). The greatest chance for severe weather and flash
flooding will be along the Central Gulf Coast where both SPC and WPC have
slight risks. Showers and thunderstorms will expand into the Tennessee and
Ohio Valleys as well along a cold front to the north. Heavy to excessive
rainfall and flash flooding will be possible with this activity too,
especially for parts of the Ohio Valley where WPC has a slight risk on
Thursday. As this system pushes east on Friday, showers and thunderstorms
will shift into the Eastern U.S. with locally heavy rainfall possible,
especially across parts of the Mid-Atlantic into the Northeast. The cold
front should clear the coast late Friday, with drier and cooler weather
expected to begin the weekend.

Temperatures across the West during the short range will be very warm
through the short range period as an upper level ridge expands across the
region. Daytime and nighttime temperatures averaging 10 to 20 degrees
above normal, especially across California and the Desert Southwest, could
approach record values for this time of the year. Meanwhile, showers and
thunderstorms this morning in the Central Plains will shift eastward along
a weak cold front into the Upper Midwest and Great Lakes on Thursday. A
surface low pressure system organizing across the Intermountain West on
Friday will allow for some rain and mountain snows in the Northern
Rockies, with showers and storms expanding into the Plains by the weekend.
Temperatures to the north of the surface low across the Northern Plains
may be cold enough to support a couple of inches of snow Friday into
Saturday for parts of the Dakotas.
