The Storm Prediction Center has issued a severe thunderstorm watch for parts of Mississippi, Louisiana and Arkansas. It goes until 2 a.m.

A strong upper level trough is approaching the South tonight. Thunderstorms are expected to develop rapidly in the next few hours in the watch area and spread eastward.

Moisture levels are increasing over Louisiana and along the Gulf Coast. A low pressure system is revving up over northern Texas. As the low moves northeast, moisture will be pulled northward.

The storms will congeal into a powerful squall line overnight. This line of storms wil move into Alabama well after midnight. The storms will produce damaging winds.

Make sure your weather radio is turned on before you retire for bed tonight. If you don’t have one, please check weather conditions periodically through the night. Be ready to follow your personal severe weather plan if severe weather warnings are issued.
