High Plains...

...Above average warmth to moderate for the Central and Eastern
U.S...

Over the next 24 hours, a developing lee-side cyclone centered
over southern Kansas is forecast to lift northeastward into the
Upper Midwest, while an associated cold front sweeps across the
Nation's mid-section. A plume of very moist and unstable air
continues to surge northward ahead of the front, which will set
the stage for several days of severe weather and heavy rainfall
across the Mid to Lower Mississippi Valleys and Mid-South. For
today, our area of concern will extend roughly along a Peoria to
Memphis line, where numerous storms this afternoon will be capable
of producing strong tornadoes, wind, hail, and scattered flash
flooding. The threat should shift into the Lower Mississippi
Valley and Mid-South by tomorrow as the cold front presses
southward and overtakes a dryline in central Texas, leading to
another round of thunderstorm clusters capable of all severe modes
(although the coverage and intensity of tomorrow's severe weather
should be lower compared to today) and scattered flash flooding.
By Wednesday, the front should continue a slow southward track,
which in turn will support another day of isolated severe storms
and flash flooding over a similar area. Meanwhile, Critical fire
weather conditions will continue over the Southern High Plains
owing to the very dry, windy, and warm airmass in place behind the
dryline where a swath of Red Flag Warnings are in effect across
portions of west Texas and eastern New Mexico.

Otherwise, much of the Central and Eastern U.S. can expect a
cooling trend through midweek as the aforementioned cold front
sweeps eastward. By Wednesday, temperatures behind the front
should moderate to around seasonal as widespread 60 and 70 degree
highs overtake areas east of the Rockies.
