KEY MESSAGES

Updated at 1140 PM CST Fri Dec 12 2025

- Low chances (15-30%) of precipitation return to the forecast Saturday night as a cold front pushes through the area (mainly near and south of the Tennessee River).

- Very cold conditions Sunday into Monday with wind chill values in the teens and single digits primarily. Some wind chills Sunday night could drop to around 5 degrees.

- An additional system is forecast to bring increased chances of rainfall by middle/end of next week.

NEAR TERM

(Tonight) Issued at 222 PM CST Fri Dec 12 2025

Temperatures climbed a bit above guidance into the lower 60s in some areas. Adjusted afternoon temperatures up slightly in response.

Expect an area of cloud cover behind the front to push further southeast into portions of southern middle Tennessee and NW Alabama overnight though as the front moves south of the area. This will bring colder and drier air into the area late tonight. Lows should drop into the low to mid 30s as a result.

SHORT TERM

(Saturday through Monday) Issued at 1140 AM CST Fri Dec 12 2025

Sunny skies allow highs to climb again to between 55 and 60 degrees, despite cooler start on Saturday.

The arctic front further to the northwest moves a bit quicker southeast than previous runs. This may limit the depth of saturation in the atmospheric column and depth of the cloud layer that actually occurs over the area. In most recent forecast soundings, this is layer of saturation is thiner. This saturated layer is mainly around 280K to 285K. Do not see much lift in that layer, so very skeptical of even low PoP (20-30%) during this time. However, kept 20 to 30 PoP in the forecast mainly near and south of the Tennessee River and portions of NE Alabama. Expect most precipitation to push east of the area after 3 AM. Even cloud cover given the isentropic downglide seen in guidance is not very certain, but kept cloudy conditions in place through 6 AM.

The truly arctic air pushing into the area behind the front on Sunday and gusty winds will be the primary concerns on Sunday. Highs will be lucky to climb into the upper 20s to around freezing despite sunny skies much of the day. Mixing to 925 mb is seen in most forecast soundings. This would enable wind gusts to reach 20 to 25 mph during the day. Sustained winds of 10 to 15 mph are expected. This will keep wind chill in the teens to single digits all day.

Bitterly cold conditions will continue Sunday night as temperatures around 20 after dusk, tumble into the low/mid teens for night time lows. Northerly winds at 5-15 mph early in the evening, will diminish below 5 mph in the overnight. For the most part, wind chill or apparent temperatures stay above 5 degrees Sunday night, which is just above our Cold Weather Advisory threshold. However, some areas in northeastern Alabama and southern middle Tennessee will need to be watched for winds chill values possibly dipping below 5 degrees.

LONG TERM

(Monday night through Friday) Issued at 222 PM CST Fri Dec 12 2025

Expect a chilly start to the work week. Under sunny skies, high temperatures Monday should rise into the mid 30s to around 40. Light northerly winds should veer to the SE-S at 5-10 mph in the afternoon. Not as cold Monday night with lows in the low/mid 20s and light winds. Conditions will moderate as we go through the mid week, with highs on Tuesday in the mid/upper 40s, Wednesday in the low/mid 50s, and in the lower 60s Thursday. Lows Tue night will range in the low/mid 30s, and in the 40s Wed night.

Clouds will also be on the increase Tuesday into Thursday, as a storm system slowly develops to our west. This next system will bring low to medium (20-50%) chances of rain to the area beginning late Wed afternoon and going into Thu. This precipitation should be more stratiform than convective in character, as it will be on the "overrunning" side of the developing system. The moisture upglide was apparent in the 295-300K regions late Wed into Thu.

AVIATION

(00Z TAFS) Issued at 544 PM CST Fri Dec 12 2025
