Severe Thunderstorm Threat From the Central Plains to the Northeast; Extreme HeatRisk for the East Coast

Strong to severe thunderstorms are possible from the central Plains to the Northeast through this evening. Widespread damaging winds are the primary threat but hail and a tornado or two is also possible. Extremely dangerous heat continues across the Eastern U.S. Warm overnight low temperatures will provide little to no relief.

...There is a Slight Risk of severe thunderstorms over parts of the Mid-Atlantic to New England on Wednesday...

...There is a Slight Risk of excessive rainfall over parts of the Mid-Atlantic, Southern Plains/Lower Mississippi Valley, and Southern High Plains/Southern Rockies on Wednesday and over the southern Mid-Atlantic and Southern Rockies on Thursday...

...There are Excessive Heat Warnings/Watches and Heat Advisories over parts of the Pacific Northwest and parts of the Southern Plains to the Lower Mississippi Valley/Southeast, and New England Coast to the Mid-Atlantic Coast...

A front extending from the Lower Great Lakes/Ohio Valley across the Middle Mississippi Valley into the Southern Plains will move slowly off the Northeast and Mid-Atlantic Coast by Friday. Also, on Friday, the southern half of the boundary will linger near the Southeast and across the Gulf Coast States.  The boundary will produce showers and severe thunderstorms over parts of Northern New England to the Mid-Atlantic. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of Northern New England to the Mid-Atlantic through Thursday morning.  The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts and a minimal threat for hail and tornadoes. 

In addition, the showers and thunderstorms will create heavy rain over parts of the Mid-Atlantic. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Mid-Atlantic through Thursday morning.  The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas the most vulnerable.

A Second area of heavy rain will develop along the front over parts of the Southern Plains/Lower Mississippi Valley. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Southern Plains/Lower Mississippi Valley through Thursday morning.  The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas the most vulnerable. 

Moreover, a third area of heavy rain will develop near the boundary over parts of the Southern High Plains/Southern Rockies. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Southern High Plains/Southern Rockies through Thursday morning.  The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, low-lying areas, and burn scars the most vulnerable.
