Unfortunately, after one of the wettest Julys on record, this is becoming old hat... Another potent upper-level trough and accompanying cold front (stronger than usual for this time of year), will move into the Mid-South today.
At 8am, storms are already firing in central AR and pushing in our general direction. The atmosphere has plenty of moisture to serve as fuel for the storms and with that abundant moisture in place, the National Weather Service has issued a Flash Flood Watch for the entire region through 7am Sunday due to the threat of 1-2" of rain from this system. We are also on the edge of a SLIGHT RISK of severe weather, as issued by the Storm Prediction Center, which encompasses much of AR, northwest MS, northern LA, and eastern TX and OK (see map above).
The main severe threat with these storms will be the possibility of damaging wind gusts. Timing for today's weather will be mainly after noon through the early overnight hours, with the best time for possible severe weather between 3-10pm. Rain could continue through a good part of the overnight hours. Sunday look to be dry and mild. Following this front, the pattern returns to a more "normal" August setup with temps in the 90s and isolated to scattered t'storms each day for most of next week.
