...Prolonged and intense heat wave continues into Friday from

Midwest to Mid-Atlantic...



...Unsettled weather could produce severe weather and excessive

rainfall for parts of the Central and Eastern U.S...



Approximately 80 million people remain under a heat headline this

afternoon as our prolonged heat wave continues for one more day

across the Mid-Atlantic, Ohio Valley, and Southeast. Within this

broad area, the Ohio Valley (along a Pittsburgh to Louisville

line) is still expected to experience Extreme to Major heat

impacts. Fortunately, relief is on the way by tomorrow evening as

the ridge flattens and a strong back-door cold front seeps

southwestward across the northern Mid-Atlantic. Behind the

back-door front, high temperatures in the low to mid 70's in the

Northeast and northern Mid-Atlantic should feel gorgeous in

comparison to the recent triple digit highs before the front

quickly weakens on Saturday. By this weekend, high temperatures in

the upper-80's and low 90's should encompass much of the region,

which is much closer to normal for late June.



As is typical of June, widespread thunderstorm coverage can be

found across much of the Central and Eastern Lower 48, generally

focusing along a slow moving frontal boundary. Some of the

organized storms in the Midwest, Mid-Atlantic, and Appalachians

today could produce scattered instances of flash flooding and

severe weather per the latest WPC and SPC forecasts. By tomorrow,

two distinct low pressure areas will split the threat of scattered

flash flooding and severe weather into the interior Northeast and

Northern Plains, respectively.
