Violent thunderstorms pounded parts of Oklahoma and Texas on Monday. Today, the threat will shift eastward into the lower Mississippi Valley.
Monday's thunderstorms on the southern Plains brought flooding downpours that dumped over an inch of rain in spots. Parts of this area were also pelted by hail while winds gusted past 50 mph.
A tornado tore through Hammon, Okla., damaging or destroying several buildings and knocking out power late on Monday afternoon. Fortunately, there were no reports of injuries.
The thunderstorms will advance into the lower Mississippi Valley today. While conditions will not be quite as favorable for severe weather, a few storms could still become strong.
Threats from these isolated storms include localized flash flooding, large hail and damaging wind gusts over 50 mph. It is not out of the question for a tornado or two to touch down.
Wednesday the storm system will reorganize, returning the risk for severe weather to a swath from eastern Oklahoma through the lower Mississippi Valley, especially during the afternoon and evening hours. This means thunderstorms capable of producing flooding downpours, roaring winds, large hail and even an isolated tornado, may be more widespread.
