KEY MESSAGES

Updated at 853 AM CDT Tue May 12 2026

- A significant warming trend will take place this weekend into early next week as daytime highs will climb into the lower 90s each day.

NEAR TERM

(Tonight) Issued at 227 PM CDT Tue May 12 2026

A beautiful day across the Tennessee Valley, with 19z temperatures in the upper 70s to lower 80s and just some scattered Cu noted on satellite imagery. These clouds will quickly dissipate after sunset as winds relax. As a result, it will be a good setup for radiational cooling in this dry air mass with a clear sky. Overnight lows will drop into the low to mid 50s in most locations, with some upper 50s noted across northwest Alabama.

SHORT TERM

(Wednesday through Thursday night) Issued at 853 AM CDT Tue May 12 2026

The last days of pleasant temperatures will occur over the next couple of days as we remain in northwest flow aloft, thanks to a broad upper trough over the Great Lakes. High pressure at the surface will still promote sunny/clear conditions both days, with a slightly warmer day on tap for Wednesday as highs in the low to mid 80s will be common (with comfortable RH values). A weak shortwave will bring a dry cold front through the area Wednesday evening/night, bringing refreshing shot of cool/dry air into the Tennessee Valley. Highs on Thursday will run about 5-10 degrees lower than Wednesday (mid/upper 70s highs) and overnight lows Thursday night will drop into the upper 40s to lower 50s (under a clear sky).

LONG TERM

(Friday through Monday) Issued at 1014 PM CDT Mon May 11 2026

These pleasantly cool temperatures will quickly come to an end as temps rise as we head into the weekend and into early next week. As we end the week, we will have a trough along the Mid Atlantic and Northeast, another trough in Manitoba, and a ridge in between. This will help boost our highs to the lower 80s on Friday.

This weekend the east coast trough will move out and the Canadian one will run over the ridge, flattening it. A few disturbances rippling through will try to bring a low chance (10-30%) of showers and a few storms on Saturday but that won't cool us down. Between the ridge and the WAA from southerly flow, highs will be set in the mid to upper 80s. A new trough sliding out from the Upper Rockies and into the Northern Plains will push the ridge eastward on Sunday and models disagree on the evolution of this trough and the effect it has on the ridge heading into next week. Regardless, temps will bring back a taste of summer with highs around 90 degrees on Sunday and in the lower 90s on Monday. Regardless, be sure to brush up on your heat safety and ensure that next weekend you know how to stay cool and hydrated. Don't forget: never leave people or pets in vehicles!

(00Z TAFS) Issued at 552 PM CDT Tue May 12 2026
