A multi-day severe weather and heavy rain threat will continue Wednesday into Thursday in the Southern Plains shifting east to the Lower Mississippi River Valley.
The severe thunderstorms will be capable of producing large hail, damaging winds and tornadoes including a few strong tornadoes possible tonight while the heavy rain may be excessive at times and produce both flash and river flooding.
The result will be rain and thunderstorms gradually spreading from the Plains toward the Mississippi Valley over the next couple days. There is a risk of severe weather and flash flooding with the thunderstorms. In general, the greatest risk for severe weather will be focused from the southern Plains into the Arklatex region tonight and Wednesday.
Tornadoes, damaging winds, and large hail will all be possible. The greatest risk of flash flooding will be focused from the central Plains into the Arklatex region. However, chances for severe weather and flash flooding will extend as far north as the western Great Lakes.
