...Warm to record breaking temperatures from Southern High Plains to
Southeast today will give way to cooler conditions late this week...

...Post-frontal rain develops across Southern Plains and Lower Mississippi
Valley on Thursday...

...Storm system brings rain and snow to the Pacific Northwest beginning
Thursday night...


A deepening low pressure system over the Central Plains will continue
pumping warm air from the South up into the Southern Plains, Mississippi
Valley and points east today. High temperatures ranging from the 70s to
80s will represent 20-30 degree departures from normal in those places.
Parts of the Southern Plains, Lower/Middle Mississippi Valley,
Tennessee/Ohio Valley, Central/Southern Appalachian Mountains and
Southeast may tie or break high temperature records as a result. Much of
the Central/Southern Appalachians and Ohio Valley will also tie or break
low temperature records as clouds associated with a strong cold front
overtake the area tonight. This cold front will usher in a period of
cooler weather for the Great Plains on Thursday before spreading the cold
airmass east into the Mississippi Valley, Midwest and Mid-Atlantic
Thursday night into Friday. The cold front finally pushes through the
Southeast this weekend.

The aforementioned low pressure system and attendant cold front will
promote post-frontal rainfall and scattered thunderstorms over parts of
the Southern Plains and Lower Mississippi Valley beginning Thursday
afternoon and continuing into Friday. 24 hour rainfall totals between 1-2
inches over the ArkLaTex shouldn't be enough to cause any flash flooding
concerns since hourly rain rates will be low. The axis of rainfall follows
the cold front south into the Texas/central Gulf Coast on Friday.
Elsewhere, snow showers spread south through the Rockies today. Shortwave
energy will bring rain/snow showers to the Pacific Northwest beginning
Thursday night.
