On April 19, forecasters said severe thunderstorms were a threat to parts of the middle and lower Mississippi Valley and the Southern Plains, and the risk could grow into Easter Sunday on April 20. The thunderstorms there could produce severe wind, hail and a few tornadoes, the weather service said.

How severe the weather will be isn't known at this time, but a forecaster said damaging wind, hail and tornadoes can't be ruled out.
