KEY MESSAGES

Updated at 940 PM CDT Mon Oct 12 2026

- Above normal temperatures are forecast through Thursday, with more Fall-like weather expected by the weekend.

- Moderate (Level 2/4) heat impacts may be observed Wednesday and Thursday across portions of the Tennessee Valley.

NEAR TERM

(Rest of tonight and Tuesday) Issued at 940 PM CDT Mon Oct 12 2026

Tranquil weather across the Tennessee Valley this evening with high pressure remaining the dominant weather feature over the area. The combination of a clear sky and calm winds will create a good setup up for radiational cooling as temperatures drop into the mid/upper 50s to lower 60s. This will also be a good setup for patchy fog development in the moist boundary layer in sheltered valleys. Any fog that does develop will dissipate by mid-morning on Tuesday. The end result will be a clear/sunny and dry day with high pressure in control of our sensible weather. With ample sunshine and light southerly winds, highs will again reach the upper 80s to lower 90s.

SHORT TERM

(Tuesday night through Thursday) Issued at 940 PM CDT Mon Oct 12 2026

A large area of high pressure will rotate over the Deep South Wednesday and Thursday, continued warm/sunny conditions will persist through much of the work week. Ample sunshine and light southerly winds will again help push high temperatures into the upper 80s to lower 90s in most locations both days, with lows remaining in the low to mid 60s. The southerly winds will also help advect moisture into the area, as evidenced by dewpoints climbing into the mid to upper 60s. Combined with temperatures in the lower 90s, this will push heat index values in the low to mid 90s and potentially create some Moderate (Level 2/4) heat impacts both days. These high temperatures are well above the seasonal norm, so continue practicing heat safety if you have outdoor plans!

LONG TERM

(Thursday night through Monday) Issued at 940 PM CDT Mon Oct 12 2026

A strong upper trough over the Great Lakes will push a strong cold front into the Ohio and Tennessee Valleys Thursday night into Friday. Not anticipating much in the way of rain chances with this feature, but some added cloud cover may accompany it as it passes through the area. The main impact will be the breezy conditions that will be observed on Friday with the passage of the front and much cooler and drier air mass that will advect into the area in its wake. Highs on Friday (the transition day) will run about 10 degrees lower than Wednesday/Thursday (highs in the lower 80s), but a strong push of cooler air will occur overnight as lows will drop like a rock into the mid to upper 40s by early Saturday morning. This autumn-like air mass will take hold on Saturday as highs in the upper 60s will be common on Saturday and the upper 60s to lower 70s on Sunday (with lows in the 40s). As ridging builds in, a gradual warming trend will take place as highs return to the mid to upper 70s by Monday.

AVIATION

(00Z TAFS) Issued at 632 PM CDT Mon Oct 12 2026

VFR weather prevailed and should continue across the Deep South through Tue afternoon. With high pressure over the region, winds should become light and variable tonight. The models were maintaining some separation between temperature and dewpoint; thus a risk for the formation of fog is low. Any fog that forms will quickly dissipate after daybreak. Light winds tonight should become SW-W around 5kt a couple of hours after sunrise.
