NEAR TERM

(Rest of tonight and Sunday) Issued at 914 PM CST Sat Feb 21 2026

Breezy NW winds are prevailing in wake of a cold front late this evening and are expected to continue for the remainder of the overnight hours. Some light drizzle was noted on radar imagery, but this will dissipate quickly over the next couple of hours. As drier air moves in, cloud cover will dissipate from west to east between 06-09z, resulting in clear conditions by early Sunday morning. However, the aforementioned breezy conditions will prevent any fog development, despite the earlier rainfall. Sunday will be a shock to the system as the northerly winds will reinforce this cool, dry air mass. Don't let the sunshine fool you, high temperatures will be running about 20-25 degrees lower than Saturday, with most locations peaking in the low to mid 40s (with wind chills in the 20s all day long).

SHORT TERM

(Sunday night through Tuesday) Issued at 914 PM CST Sat Feb 21 2026

Winds will remain breezy Sunday night and with low stratus remaining to our north and east as a weak shortwave clips the area. As a result, a hard freeze will be in store for the Tennessee Valley, with lows in the low to mid 20s being common (and wind chills as low as 6 to 12 degrees)! Monday will be an even colder day as another shortwave trough (and its associated dry cold front) clips the area, with highs barely making it above the freezing mark -- peaking in the mid to upper 30s. Another freeze will be in store for the area Monday night, with lows dropping to the upper Teens to lower 20s. Some gradual relief will be in store by Tuesday as high pressure at the surface begins to build back from the west. Ample sunshine and southerly winds will allow high temperatures to modify into the low to mid 50s in most locations.

LONG TERM

(Tuesday night through Saturday) Issued at 914 PM CST Sat Feb 21 2026

Clouds will increase Tuesday night into Wednesday ahead of an approaching frontal system. Despite the cloud cover, southerly winds will help to push high temperatures back into the low to mid 60s. Another fast-moving trough will ripple through the Tennessee Valley Wednesday night into Thursday, bringing medium to high chances (50-80%) for rain showers along and ahead of a cold front. This activity will taper off from west to east Thursday night, with some decent wetting rains of between 0.5" to 1.0" forecast. Thereafter, we will remain in zonal flow aloft and in a mild pattern to close out the month of February, with partly cloudy conditions and southerly winds keeping highs in the 60s and lows in the 40s.

AVIATION

(00Z TAFS) Issued at 604 PM CST Sat Feb 21 2026

Broken-overcast layers of As will continue at the MSL/HSV terminals early this evening, as atmospheric lift strengthens ahead of an approaching shortwave trough (extending from western TN into north TX). Although light returns in radar reflectivity data may yield a few sprinkles of rain, much of this will occur as virga, with higher probabilities for precipitation reaching the sfc located across TN. SKC conds are expected to return by 3Z/MSL and 4Z/HSV as the trough shifts quickly eastward, but a pocket of very cold air aloft will support development of scattered cold air stratocu once again by 15Z. Sfc winds will remain from the NNW for the duration of the TAF period, with speeds of 10G20 kts overnight increasing to 14G24 kts after sunrise.
