KEY MESSAGES

Updated at 1033 PM CDT Thu Jun 11 2026

- Low to medium chances for showers and storms are forecast on Saturday, with localized gusty winds and heavy downpours the main threats.

- Additional rounds of showers and thunderstorms are forecast Sunday and Monday as a frontal system passes through the region. Strong gusty outflow wind gusts, and locally heavy rainfall and flash flooding will continue to be a concern during this timeframe.

NEAR TERM

(Rest of tonight and Saturday) Issued at 1033 PM CDT Fri Jun 12 2026

Tranquil weather across the Tennessee Valley this evening with remnant light rain showers over NW Alabama quickly dissipating with the setting sun. Main question for tonight is how much cloud cover thins out, but given recent satellite trends think that some decent clearing will take place by early Saturday morning. Rainfall amounts were generally lighter than expected earlier today, but the moist boundary layer and partial clearing may lead to some patchy fog development for a few hours early Saturday morning. A weak frontal boundary will remain stalled just south of the region on Saturday and serve as a focus for additional convection (30-40%) during the afternoon and evening hours. This activity will be diurnally driven and pulse-like in nature. Given the very moist environment and slow storm motions, locally heavy downpours and flooding will be the biggest concern with the strongest activity -- along with gusty winds. In addition to the storm chances, expect another very warm day with highs rising into the upper 80s to lower 90s, and corresponding heat index values in the 96 to 102 degree range.

SHORT TERM

(Saturday night through Monday) Issued at 1033 PM CDT Fri Jun 12 2026

Saturday night a fast-moving shortwave will shift from the central Plains into the mid Mississippi and Ohio Valley. A complex of storms will form ahead of a front to our northwest that will track toward the region overnight. If it can hold together, it may move into the region during the predawn hours on Sunday (09-12z), bringing strong winds gusts and heavy downpours for Sunday morning. With the boundary draped across the region on Sunday, additional rounds of showers and general thunderstorms will occur (70-80% chance), with heavy downpours and localized flooding again this biggest concern. Guidance within the last 24 hours has trended faster with the frontal passage and shows it dropping south of the region Sunday evening into Sunday night, with some low to medium (30-60%) for showers and a few storms continuing during this window. With the boundary just south of the region on Monday, our highest PoPs will be displaced over central and south Alabama -- with low to medium (20-40%) of some showers and storms in the afternoon once again. The main story for Monday will be the much cooler temperatures as highs will drop into the upper 70s to lower 80s.

LONG TERM

(Monday night through Friday) Issued at 1033 PM CDT Fri Jun 12 2026

The TN Valley will be on the northern side of a cold front as we head into the long term period, bringing a temporary but much welcomed break from the heat and humidity. In fact, temps will fall to the low to mid 60s Tuesday morning with highs in the upper 70s/low 80s in the afternoon. Upper troughing will shift east through the eastern CONUS, pushing high pressure and dry conditions into the area on Tuesday before a return to southerly flow brings low chances for mainly diurnal showers and storms Wednesday. Temps will be on the rise during the mid-week period as well with highs approaching the upper 80s to lower 90s Wednesday and Thursday. Higher rain chances (60-80%) toward late next week as another upper wave and associated cold front approaches the area.

The forecast for next week still remains of lower confidence given model discrepancies at this range, but the threat for flash flooding early next week appears lower than in previous days.

AVIATION

(06Z TAFS) Issued at 1151 PM CDT Fri Jun 12 2026

VFR conditions will prevail overnight and into early Saturday morning with just some passing high clouds overhead. However, a brief period of light fog may develop early Saturday morning between 09-12z and have added a TEMPO to highlight this at both terminals. Cu will redevelop Saturday afternoon, with a low chance of storms in the afternoon. However, confidence is too low in coverage and location to mention in the TAF at this time.
