We continue to have a mass of rain and thunderstorms pushing across the south-central parts of North Alabama and the extreme north-central parts of Central Alabama. We also have some scattered shower and thunderstorm activity over the eastern and northeastern parts of Central Alabama. All of this activity is pushing eastward at 20-25 MPH.
Latest HRRR run valid from 1:00 pm today to 1:00 am Thursday morning.
The latest HRRR is showing that much of the activity will stay over the northern half of the state throughout the remainder of the day and into the late-night hours, even though there looks to be some isolated to scattered showers and storms that may develop south of the I-20 corridor in the mid to late afternoon hours.
So for the rest of the daylight hours, we can expect a chance of isolated to scattered showers and storms in the southern half of Central Alabama while there will be a much higher chance of scattered to numerous showers and storms in the northern half. So rain may be heavy at times and some localized flash flooding could occur. With precipitable water values over 2 inches for the area, rainfall rates with some of these storms could reach as high as 2 inches per hour. Afternoon highs will be in the upper 80s to the mid-90s across the area from north to south.
Tonight, while much of the activity will diminish across the area, a few lingering showers and storms could hang around across the area into the late night and overnight hours. The higher rain chances will be over the northeastern parts of the area. Overnight lows will be in the lower to mid-70s.
Thursday looks to be a more typical summertime day across Central Alabama. We’ll have some sun early with convective clouds building during the heating of the day. We’ll have the standard chance of isolated to scattered mainly afternoon showers and thunderstorms from west to east. Afternoon highs will top out in the lower to mid-90s with heat indices in the 100-103 degree range for most.
TROPICS: The Atlantic Ocean, Caribbean Sea, and the Gulf of Mexico are free from any tropical activity at this point, and no new tropical systems are expected to develop within the next five days. The low associated with the remnants of Barry is located over northern Ohio today and is expected to wash out by Thursday.
