Heat Advisories continue for portions of central Alabama through 7 PM today and the northern sections until 7 PM Friday.
Rain and thunderstorms across the northern half of the state will be ending this morning with decreasing clouds statewide by early afternoon. This will not only raise heat index values to 103-110 in the advisory areas but also increase atmospheric instability as well.
Scattered thunderstorms are forecast to develop mid to late afternoon across Alabama and continue well into the evening. The threats are heavy rainfall, frequent lightning, a few wind gusts from 40-60 mph and hail. There is no tornado threat. If new model data shows slightly more instability than currently forecast, the SPC may upgrade portions of the state to Slight Risk later today.
The very active pattern will continue from Friday into the middle of next week with scattered to numerous showers and thunderstorms each day, mainly during the afternoon and evening hours. Storms each afternoon and evening could produce a few wind gusts from 40-60 mph, but widespread severe weather is not anticipated.
