There is a slight risk of severe thunderstorms across eastern
portions of North Carolina and southeastern Virginia. Please refer to the Convective Outlook products issued by the Storm Prediction Center for further details on the severe weather threat.
Scattered showers and thunderstorms will remain possible across the Southeast through Sunday as the frontal boundary lingers.
Behind the cold front, a pleasant airmass more typical of early fall will move into areas from the Midwest to the Northeast with below average temperatures and humidity expected.
The frontal boundary extends northwestward across the southern plains into the central Rockies. The boundary will act as the focus for rounds of showers and thunderstorms to develop across the central U.S. tonight, which will move into the Mississippi River valley by Sunday night.
The Storm Prediction Center is forecasting a slight risk of severe
thunderstorms through tonight across portions of the High Plains.
Additionally, heavy rain and flash flooding are possible tonight and
