KEY MESSAGES

Updated at 1053 PM CDT SUN Mar 29 2026

- Isolated to Scattered showers and thunderstorms could develop on Tuesday afternoon.

- Showers and thunderstorm chances increase starting Wednesday through Saturday. Some stronger storms could develop by Saturday night into Sunday.

NEAR TERM

(Rest of tonight and Monday) Issued at 1053 PM CDT Sun Mar 29 2026

Winds will stay up between 5 and 10 mph into the early morning hours, before becoming light less than 5 mph towards daybreak on Monday. Cloudy conditions east of the I-65 corridor should spread east overnight and into the day on Monday. Winds and partly to mostly cloudy conditions will likely keep low temperatures a bit warmer than originally thought, only dropping into the 52 to 57 degree range on Monday morning.

Southerly low level flow will continue into the day on Monday, advecting more moist air into the region. Surface dewpoints should climb into the mid 50s to lower 60s as a result. Cloud cover will help keep highs in the mid to upper 70s. The western edge of the upper ridge should keep any precipitation from occurring on Monday.

SHORT TERM

(Monday night through Wednesday) Issued at 1053 PM CDT Sun Mar 29 2026

Monday night should see some decrease in cloud cover from southwest to northeast, mainly after midnight. Continued southerly flow will make for a humid night with lows only dropping into the 60 to 65 degree range.

At the same time, a longwave trough axis continues to be shown stretching from the Upper Midwest SSW into the Southern Plains. By Tuesday, continued SSW flow and some weak disturbances moving north from the Gulf of Mexico around the west side of the upper ridge could start producing some isolated to scattered showers and maybe some thunderstorms. Shear remains very weak, so if any thunderstorms develop, they will be mainly lightning and heavy downpour producers. Not much changes through Wednesday with some cloud cover and highs in the 80 to 85 degree range.

LONG TERM

(Wednesday night through Sunday) Issued at 1053 PM CDT Sun Mar 29 2026

These trends continue into the day on Thursday with the upper ridge shifting further east and strengthening off the Atlantic coast. This really proves as an impetus for the longwave trough axis earlier mentioned to push into the Tennessee Valley. However, another longwave trough axis moves into the central CONUS by early Thursday afternoon. This feature pushes east into the upper ridge Thursday night, but most guidance really weakens this as it tries to do that. That being said, some stronger forcing will push into areas west of the I-65 corridor during that period. Given the very moist environment though and some instability, some more widespread showers and thunderstorms look very possible. Again shear is very weak, so no strong to severe storms are expected at this time. Thursday looks warmer with less cloud cover early, before increasing in the afternoon. Highs could reach the lower to mid 80s.

During the day on Friday, the stronger forcing pushes east across northern Alabama. This likely will be our most widespread period of showers and storms, but not expecting alot of rainfall (only between around one half of an inch). Again not much shear, so mainly showers and general thunderstorms are expected.

At the same time on Friday, a stronger storm system pushes from the Pacific Northwest into the Central Plains. The front over the area generally just weakens and stalls just east of Alabama. Given the weakening of the system, only scattered showers or thunderstorm chances should continue, but they should be garden variety. Cloud cover should keep highs in the upper 70s/lower 80s.

The stronger storm system moves from the Central Plains into Ohio Valley region by Saturday. Models hint at much stronger dynamics ahead of this system developing. However, the strong upper ridging builds back to the southwest into the area. This will keep stronger forcing ahead of this next system to our west through Saturday afternoon.

Stronger forcing ahead of the system will push into the area Saturday night into Sunday. Overall the system weakens from earlier strength. However, strong forcing will still be in place ahead of it. So widespread rainfall and some thunderstorms are expected Saturday night into Sunday. Shear is around 30 to 35 kts, so a low end strong to severe setup may develop with that system.

AVIATION

(06Z TAFS) Issued at 1128 PM CDT Sun Mar 29 2026

VFR conditions are expected at KHSV through 9Z. Included a tempo group for lowering CIGS into the MVFR realm between 9Z and 13Z. This may need to be made a predominant group and maybe lasting a bit later. However, not sure if these lower CIGS will remain more east of KHSV. Further west, guidance suggests cloud cover will remain more scattered overnight, before VFR CIGS push into the KMSL terminal around 18Z. VFR CIGS are forecast to returned to KHSV in this issuance after 13Z. Winds will become more southerly during the day on Monday.
