KEY MESSAGES

Updated at 820 AM CDT Mon Mar 30 2026

- A warm, moist air mass will remain in place through the week, with highs in the upper 70s to lower 80s each day, with lows in the 60s. - Low chances for showers and a few thunderstorms will return to the forecast on Tuesday.

- Showers and thunderstorm chances increase starting Wednesday through Saturday. Some stronger storms could develop by Saturday night into Sunday as cold front moves through the region.

NEAR TERM

(Rest of Today and Tonight) Issued at 820 AM CDT Mon Mar 30 2026

Southerly flow and broken decks of stratus have kept temperatures on the mild side this morning, with 13z readings in the upper 50s to lower 60s. These clouds will hang around through midday, before gradually breaking up by the early to mid afternoon. Warm air advection and some additional heating later in the day should be able to warm high temperatures into the upper 70s in most areas by this afternoon. Winds may become gusty again this afternoon, but they will remain out of the south (keeping Min RH values above 50 percent). We'll remain fairly mild again overnight some cloud cover returns after midnight, with lows remaining above 60 degrees in most locations.

SHORT TERM

(Tuesday through Wednesday) Issued at 820 AM CDT Mon Mar 30 2026

High pressure will continue to push off to the east (off the coast of the Carolinas), but the Tennessee Valley will still remain under its influence for the remainder of the week. As a result, south to southwest flow will continue to reinforce a warm, moist air mass across the region both Tuesday and Wednesday. Meanwhile, a broad upper-trough over the Central/Southern Plains will amplify as it attempts to push northeast into the upper-Mississippi Valley and Great Lakes. A couple weak shortwaves will ripple across the Mid South and Tennessee Valley along the southern edge of this feature both Tuesday and Wednesday. Though forcing will be fairly weak, sufficient moisture will be present to generate some low chances of showers and thunderstorms (20-30%) on Tuesday and low to medium chances (30-50%) on Wednesday. This activity, won't be organized due to the weak shear and modest instability. Despite the afternoon cloud cover and storms, southerly and partial sunshine should allow highs to warm to the lower 80s both days.

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 a lot 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

(12Z TAFS) Issued at 638 AM CDT Mon Mar 30 2026

VFR conditions will return this morning with the mid level stratus deck beginning to clear later today. Winds will become more southerly today, and could gust up to 15-20kts at times this afternoon at KMSL.
