KEY MESSAGES

Updated at 1005 PM CST Sun Dec 21 2025

- No significant weather impacts expected for the next 7 days.

NEAR TERM

(Today) Issued at 410 AM CST Mon Dec 22 2025

Early morning temperatures range from the low/mid 30s in northern portions of the area to the mid/upr 40s in S/SE counties. Satellite imagery shows low stratus clouds have been present during the night to our SE. However, as the sfc ridge shifts eastward into the mid-Atlantic/Piedmont region, deepening SE-S flow in the low-levels is beginning to push this cloud deck northward. Continued veering low-lvl flow just aloft during the morning and into the afternoon will result in moisture advection and isentropic ascent focused around 800-900 mb. Thus, the stratus deck is expected to develop northward and encompass most of the area resulting in mostly cloudy conditions today. Some regional radars to our south have begun to indicated spotty areas of -DZ. Drizzle has not been introduced into our forecast yet for today, but would tend to be light and spotty if it manifests. Clouds will limit warming, but highs in the mid/upr 50s appear likely despite the cloud presence.

SHORT TERM

(Monday night through Wednesday) Issued at 1005 PM CST Sun Dec 21 2025

Very low chances (mainly 20 to 25%) are in the forecast and mainly for extreme NW ALabama and our southern middle TN counties Monday night through Tuesday night, before ending. Very little rainfall is expected through that period. But a few hundredths here or there could occur. However, we will likely see very little sunshine due to persistent cloud cover. The exception might be south of the Tennessee River on Tuesday. Stronger southwesterly flow develops during that period. This will push highs Tuesday and Wednesday into the mid 60s to lower 70s.

LONG TERM

(Wednesday night through Sunday) Issued at 1005 PM CST Sun Dec 21 2025

Lows will remain in the lower to mid 50s Tuesday night with some early cloud cover lingering. Even warmer conditions are expected on Christmas Day, as upper level ridging remains over the Gulf Coast states into northern Alabama. Highs by Christmas Day will likely be in the lower to mid 70s, despite some clouds at times.

Another frontal boundary moves through the area on Friday. A few models do show some very light rain with it, but not much. Increased cloud cover and some weak cold air advection will drop highs a tad into the mid 60s to lower 70s on Friday. However temperatures quickly warm behind it into the 70 to 75 degree range on on Saturday.

AVIATION

(12Z TAFS) Issued at 530 AM CST Mon Dec 22 2025

Low stratus clouds with bases at VFR/MVFR height ranges continue to spread towards KHSV and KMSL TAF sites this morning. Currently, forecast favors VFR ceiling conditions at KHSV through ~06Z, but confidence is low as cloud bases are close to MVFR and amendments may be necessary. At KMSL, confidence is higher in MVFR, but ceiling impacts may occur earlier than 00Z in the latest TAF, and likewise, amendments could be necessary. Otherwise, a brief period of LLWS looks likely to occur at both TAF sites, which is supported by local MIPS profiler data.
