KEY MESSAGES

Updated at 1122 AM CDT Sun Oct 18 2026

- Cooler temperatures will persist through tonight, before a warming trend takes shape early to mid week.

NEAR TERM

(Tonight) Issued at 255 PM CDT Sun Oct 18 2026

Temperatures have warmed into the 65 to 70 degree range across northern Alabama and southern middle Tennessee. We could see a few lower 70s before the day is done. Afternoon relative humidity values have dropped into the 25 to 30 percent range some locations. Winds have dropped off to around 5 mph or less. Models are still forecasting 925 mb winds to pick up to between 15 and 25 mph tonight. Thus, still believe that this will setup a ridge valley split situation overnight into Monday morning with low temperatures. Lows in sheltered valley locations should be light and variable which should allow temperatures to drop into the upper 30s to lower 40s. In higher elevations, winds should remain stronger overnight around 5 to 10 mph with maybe a few higher gusts. Also, expect drier air to push west into the area. Thus, fog or frost is not expected, especially with higher temperatures that were reached earlier this afternoon.

SHORT TERM

(Monday through Wednesday) Issued at 1122 AM CDT Sun Oct 18 2026

The upper ridge and surface high remain in place over the eastern CONUS through Tuesday. This should allow for a slow warming trend to occur. Highs by Monday should climb into the lower 70s with lows only dropping into the 40s Monday night. By Tuesday highs should rebound into the lower to mid 70s with continued sunshine.

By Tuesday night, a weak/dry frontal boundary will slip east through the area. This will not have much impact on temperatures, but will retrograde the upper ridge axis to the west of the area briefly. The main effect will be some slightly drier air will push back into the area.

By Wednesday, the upper ridge tries to build slightly further east back into the area, but we will still be in NW flow aloft. This will likely keep highs in the lower to mid 70s, despite abundant sunshine.

LONG TERM

(Wednesday night through Saturday) Issued at 1122 PM CDT Sat Oct 17 2026

Upper level ridging will build back over the Southeast towards the end of next week. The surface high pressure looks to largely maintain its hold over much of the eastern CONUS through the first part of next weekend. Overall, with continued subsidence from surface high pressure and proximity of upper ridging, the current forecast remains devoid of rain chances through at least early next weekend. In addition, the Fall-like weather continues with forecast highs in the mid to upper 70s and lows mainly in the mid to upper 40s.

AVIATION

(18Z TAFS) Issued at 1134 AM CDT Sun Oct 18 2026

VFR conditions are expected throughout the TAF period at both terminals. Southeasterly winds between 5 and 10 knots with higher gusts this afternoon will decrease and become more easterly this evening. Winds around 4 or 5 knots are expected much of the evening into the daybreak hours on Monday. This and drier air advecting into the area in the boundary layer should keep fog at bay. Winds should remain from the east around 5 knots into the day on Monday.
