...Isolated-scattered severe Weather and flash flooding possible over the
Ohio Valley, Mid-Atlantic, and Gulf Coast today...

...Above average temperatures across southern tier states and West; below
average temperatures from Northern Plains to Northeast/Mid-Atlantic...

Two low pressure centers will continue to focus isolated-scattered showers
and thunderstorms along a pair of associated cold fronts across the Ohio
Valley into the Gulf Coast states. After a soaking rainfall swept through
this morning, additional development could yield scattered flash flooding
in a relatively confined area over portions of the Central Appalachians,
including over the Pittsburgh metro where a Flood Watch is in effect. To
the south and west of the main excessive rainfall area, SPC has outlooked
several focused areas over the Mid-Atlantic, Gulf Coast, and Ozarks for
the threat of scattered severe storms capable of producing large hail,
strong winds, and a tornado or two. Additional severe weather is possible
tomorrow over the Southern Plains, although when compared to the recent
widespread coverage of severe and flash flooding the pattern for the next
two days appears far more tranquil.

Rainfall aside, an upper low parked over the Great Lakes and Northeast
will facilitate cooler temperatures across the Northern Plains, Midwest,
Northeast and Mid-Atlantic for the next several days. High temperatures in
the 40s, 50s and low 60s will represent temperature anomalies between
20-35 degrees below average. Meanwhile, an upper ridge in the West and
central U.S. will produce above average temperatures across the Southern
and Western U.S.. Some high minimum temperature records may be tied or
broken in Florida and southern California. Meanwhile, moderate to locally
Major HeatRisk will increase over south Texas beneath a building upper
ridge through the rest of the week.
