Fortunately, there have been no reports of severe weather overnight, as instability was low enough to inhibit strong to severe thunderstorm growth.
For today, there remains a Slight Risk threat near and south of Hwy 80/I-85 with a Marginal Risk northward to I-20. As rain and thunderstorms continue to move across the northern and central sections of the state, the precipitation in the southern half will slow its eastward progress this morning. This will allow the atmosphere to recover with the potential for an increase in instability from late morning into the afternoon in the southern areas of AL.
There still remains plenty of wind shear which will promote rotating storms if enough instability develops. As a result, a few damaging wind gusts and a couple of tornadoes are possible, especially across the Slight Risk area. In addition, another 0.5 – 2 inches of rainfall will occur with potentially higher amounts across south Alabama. This could lead to brief and isolated flash flooding.
Non-thunderstorm wind gusts from 20-30 mph will occur through the afternoon across the eastern and southern portions of the state.
After today, a few showers are possible Thanksgiving night into Friday, but most locations will remain dry through Sunday evening with no severe weather.
