KEY MESSAGES

Updated at 1106 AM CDT Sat Oct 17 2026

- A breezy/very cool day on tap today with highs only in the upper 50s to around 65 degrees. A slow warm up to more typical fall temperatures are expected into next week.

- Northerly winds of 10-15 MPH (with gusts up to 20-30 MPH) will last through this afternoon.

- Patchy frost may occur early Sunday and Monday mornings in a few wind-sheltered locations across southern TN and northeast AL.

NEAR TERM

(Tonight) Issued at 318 PM CDT Sat Oct 17 2026

Cloud cover has primarily dissipated in most areas, though some scattered cumulus is lingering in portions of NE Alabama. Temperatures have climbed into the 59 to 64 degree range so far and could top out around 65 degrees in a few spots.

N to NNE winds of 10 to 20 mph with some gusts up to 30 mph will likely remain possible into very early evening hours before beginning to weaken. Many areas will likely see winds around 5 mph last through much of the night though. The exception to this will likely be in southern middle Tennessee and maybe some isolated sheltered valley locations in NE Alabama. In those areas, could see some isolated patchy frost. Due to its expected isolated coverage, little to no impact is expected. If forecast trends for winds weaken more than expected tonight, a frost product may have to be considered in northern Alabama. Lows should drop into the 39 to 45 degree range in most areas. In sheltered valley locations of NE Alabama and portions of southern middle Tennessee, some lows could drop to between 36 and 39 degrees.

SHORT TERM

(Sunday through Tuesday) Issued at 1106 AM CDT Sat Oct 17 2026

Upper level ridging builds east into the Tennessee Valley in earnest on Sunday in most guidance. As the pressure gradient weakens, winds between 5 and 10 mph are expected. It should be warmer on Sunday with abundant sunshine. Highs should climb back into the mid 60s to around 70 degrees. Even drier conditions are expected in the afternoon, as even better mixing of drier air aloft is expected to occur for a longer period on Sunday. RH values in the afternoon will likely drop to between 25 and 30 percent in many areas. Just a tad warmer lows are expected Sunday night, mainly dropping to between 38 and 46 degrees in most areas.

The surface high and upper level ridging remains in place over the eastern CONUS on Monday. With sunny skies and a bit more of an easterly low level wind component upstream, temperatures should continue to trend warmer, reaching the upper 60s to lower 70s in the afternoon. Winds should be just bit lighter from the E or ESE. Models are hinting that easterly flow will advect even drier air into the area (dewpoints in the lower to mid 30s primarily). This and slightly higher low temperatures should keep frost at bay.

Monday night lows will slowly continue to warmup dropping into the 40 to 45 degree range under clear skies.

LONG TERM

(Tuesday night through Friday) Issued at 1106 PM CDT Fri Oct 16 2026

Overall, it looks like the Fall-like weather will largely continue through Friday. A stout upper ridge will build over the central CONUS and into the South this next week as an upper trough persists over the eastern seaboard. By Thursday/Friday, the upper ridge starts to push eastward as a shortwave trough swings over the north-central portion of the country. Meanwhile, surface high pressure looks to remain entrenched over the Great Lakes and down into the Deep South through the week. Overall, little to no rainfall will be the theme through this next work week. Highs warm into the 70s for much of the week before increasing into the lower 80 degrees for some locations by late week as the axis of the aforementioned upper ridge moves over the the region. Lows will generally remain in the 40s for most of the week. Although, some locations may see lows around 50 degrees by Thursday night. Ultimately, it might be a good idea to grab at least a light jacket when heading out the door this week!

AVIATION

(18Z TAFS) Issued at 1230 PM CDT Sat Oct 17 2026

VFR conditions are expected throughout the TAF period. Sustained N to NNW winds between 10 and 15 knots gusting to around 25 knots are expected into the afternoon hours before becoming lighter. These winds are expected to drop to around 5 knots later this evening. Clear skies will continue with winds becoming more easterly on Sunday around 5 mph or less.
