A large storm system is gaining strength over the Central Plain states as a powerful upper level jet roars eastward. Surface low pressure is moving east this evening across Oklahoma with showers and thunderstorms developing across the Ozarks well in advance of the cold front. This is setting the stage for active thunderstorms across the deep south on Wednesday into Thursday.
In response to our upper level system, surface winds will increase allow for moisture to stream northward across the Gulf Coast states. Rain and Thunderstorms will develop during the day Wednesday across Louisiana, Arkansas, and Mississippi where some severe weather will be possible. This activity will move into Central Alabama on Wednesday night. Rainfall on the order of 1-2" will be possible with the best chance of thunder south of the Interstate-20 corridor.
After the storms on Wednesday night, redevelopment is possible Thursday afternoon. The airmass will become unstable and allow for the potential for some severe thunderstorms. For detailed information on the impending situation visit the Alabama Storm Trackers link.
