KEY MESSAGES

Updated at 1200 PM CDT Sun May 10 2026

- A low chance of thunderstorms across northwest AL this afternoon.

NEAR TERM

(Rest of Today and Tonight) Issued at 923 AM CDT Sun May 10 2026

Satellite imagery continues to show the dense fog this morning gradually thinning out. However, it is still quite thick along the Tennessee River and in the valleys in NW AL. Therefore we have extended the Dense Fog Advisory until 10 am this morning. The fog will transition briefly to a low stratus deck before completely mixing out with mostly sunny skies returning by around lunchtime.

For Mother's Day, most locations across the Tennessee Valley will stay dry with the lone exception being in portions of NW AL. Radar imagery shows a decaying MCS in southern AR slowly pushing eastward. Daytime heating across northern MS will likely trigger some new convection along any lingering outflow boundary ahead of the aformentioned MCS. As these storms push eastward towards NW AL this afternoon, they will encounter a much more stable airmass and are expected to gradually weaken as they reach the AL/MS state line. Therefore, cannot completely rule out a shower or thunderstorm in far NW AL, but these will not be severe. For the rest of the area, dry and warm conditions are forecast with afternoon highs in the lower 80s.

A cold front is expected to push through the area overnight. This will bring a low chance (20-30%) of showers as the front passes through the area. Latest model guidance continues to trend drier and would not be surprised if some places do not see any rainfall overnight.

SHORT TERM

(Monday through Tuesday) Issued at 923 AM CDT Sun May 10 2026

Some lingering showers may persist into the morning hours on Monday. Cloud cover will be slow to erode as the cooler airmass lags well behind the front. Cooler and drier air finally advects into the region during the second half of the day Monday as northwest flow aloft sets up across the Southeast. Temperatures on Monday and Tuesday will rise into the mid to upper 70s with overnight lows in the upper 40s to lower 50s.

LONG TERM

(Tuesday night through Saturday) Issued at 944 PM CDT Sat May 9 2026

Tuesday night clear skies and light winds will help lows dip into the lower 50s. On Wednesday, high pressure will get shoved eastward as a trough moves across the Great Lakes. The cold front associated with the sfc low up there will trail through the OH Valley, into the Mid MS Valley and back into the Southern Plains. The front will move through Wednesday evening or night and it is trending to only provide a few showers. Afternoon highs should be able to reach around 80 degrees. We will be postfrontal on Thursday and high pressure will build in across the Great Lakes on down to the Lower MS Valley. This will provide highs in the mid/upper 70s under a sunny sky and lows around 50 degrees. The upper level ridge will glide through the Southeast on Friday, but be dampened by a shortwave running into it on Saturday. It will keep conditions dry during this time, but raise temperatures. Look for highs in the lower 80s on Friday and the mid to upper 80s on Saturday.

AVIATION
