KEY MESSAGES

Updated at 937 PM CDT Sun Aug 2 2026

- Low to Medium chances (20-60%) for showers and thunderstorms are forecast each afternoon today through Wednesday. Slight lower chances of activity are expected Thursday and Friday (20-40%). - NWS Heat Risk highlights Moderate (Level 2 of 4) heat impacts across the Tennessee Valley late this week (Thursday through Sunday).

NEAR TERM

(Rest of tonight and Monday) Issued at 937 PM CDT Sun Aug 2 2026

Light to to moderate showers continue to advance east across the area this evening as an axis of moisture associated with an upper wave/vorticity max slowly pushes through the TN Valley. This is happening in the wake of a cold front that resulted in seasonably cool conditions today. We expect the rain to tapper off overnight when the concern turns to the potential for patchy fog or low stratus that may cause lower visibilities during the morning commute. Patchy to areas of dense fog was added to the forecast overnight into early tomorrow morning, and we will monitor in case conditions warrant a dense fog advisory.

Moisture associated with the aforementioned wave will continue to slowly track east on Monday when a cutoff low is expected to form over northern/central GA. This will keep low to medium chances (20-45%) for rain and thunderstorms in the forecast mainly east of I-65 during peak daytime heating hours. Still in the wake of a cold front, temps will remain on the cooler side tomorrow topping out in the low to mid 80s.

SHORT TERM

(Monday night through Wednesday) Issued at 937 PM CDT Sun Aug 2 2026

The synoptic level pattern changes very little in the short term period, keeping low to medium chances (20-60%) in the forecast through Wednesday, with the highest chances over areas east of I-65. While periods of sun may peek out, expect cloudy conditions each day especially over eastern areas. The good news is that with the exception of locations over far NW AL on Wednesday, high temps should remain on the cooler side of seasonal norms topping out in the 80s. Enjoy the "cooler" weather while it lasts, because another round of summer heat is coming by the end of the week.

LONG TERM

(Wednesday night through Sunday) Issued at 937 PM CDT Sun Aug 2 2026

Wednesday night the cut off low will finally shift eastward as a trough axis moves into the Midwest and skies will become partly cloudy across the TN Valley. Will see a low chance (20-30%) of showers and thunderstorms mainly east of I-65 Thursday afternoon. A little bit higher rain chances on Friday afternoon as the trough axis makes it into the OH Valley and sends a disturbance into the TN Valley. The sfc low lifts into the Lower Great Lakes while the associated cold front will not make much southern progress, remaining up in the OH Valley. Not much of a pattern change over the weekend as it looks like the front will not make it into the region and we will continue to get diurnally driven showers and thunderstorms.

Temps will be in the upper 80s to lower 90s Thursday through Sunday but the heat index will make it feel more like it is in the upper 90s to just above 100 degrees. Not reaching heat advisory thresholds, however with most of us returning back to school this week, heat safety needs to remain a priority.

AVIATION

(06Z TAFS) Issued at 1237 AM CDT Mon Aug 3 2026
