We're monitoring a powerful system that is expected to impact the Southeast on Saturday. This system will likely bring some cooler temperatures to the area, but also a chance for thunderstorms. If you have outdoor or weather dependent plans Saturday afternoon or evening, it would be a good idea to stay weather aware over the next few days. I'm NOT seeing indications now of a significant severe weather event, but I would prepare for some stronger storms late Saturday and possibly extending into Sunday morning.
The Setup: Moisture and warm air will surge ahead of the cool front. Expect dew point temperatures in the lower to mid 60s by the afternoon. The severe weather parameters are modest, but there will be enough instability for some pretty good rounds of thunder as a cool front tracks across the state.We'll go from highs in the 80s Saturday to highs in the mid 60s on Sunday.
Timeframe: Saturday morning looks dry with mostly sunny weather. The temperatures will likely climb into the lower to mid 80s during the afternoon with thunderstorms developing during the afternoon and evening. Rain chances are around 60-percent. It is possible we could continue to see some rain and thunderstorms through Sunday morning.
Impacts: This will likely be a line of storms ahead of a strong cool front. The primary threat will be gusty winds, lightning, heavy rain, and possibly damaging winds. The best chance for stronger storms looks to be west of I-65 and north of I-20. I'd be particularly weather alert in Tuscaloosa, Pickens, Lamar, Marion, Winston, Fayette, and Walker Counties.
I'm off a few days, but Wes, Jill, and Mickey will be watching this system. In the meantime, expect a pretty good chance of scattered showers/storms both today and tomorrow.
