KEY MESSAGES

Updated at 323 AM CST Fri Dec 12 2025

- Low chances (20-30%) of precipitation return to the forecast Saturday night as a cold front pushes through the area.

- Very cold conditions Sunday into Monday with wind chill values around 5 degrees through most of the area.

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

NEAR TERM

(Today) Issued at 323 AM CST Fri Dec 12 2025

Early this morning some passing clouds were noted on satellite imagery, but otherwise tranquil conditions continue across the Tennessee Valley. With high pressure at the surface in control of our sensible weather and winds veering to the south, temperatures will rebound nicely today (especially once clouds begin to thin later in the day). Highs in the mid to upper 50s will be common, with a few locations reaching the lower 60s.

SHORT TERM

(Friday night through Sunday) Issued at 943 PM CST Thu Dec 11 2025

Our main concerns in the short term period are the very cold temperatures and wind chill temperatures forecast to move in Saturday night into Monday morning. An upper level low is forecast to shift eastward into the Appalachian region on Friday, bringing a cold front southeastward through the TN Valley. An additional low pressure system is forecast to traverse eastward through the Great Lakes region, bringing a secondary cold front to the area by Saturday night. This secondary front is forecast to bring very cold conditions to the TN Valley by the late weekend. Ahead of this, a low chance (10-30%) of precipitation will be possible Saturday evening into early Sunday. Model soundings have been trending drier (both in the snow growth region as well as throughout the profile), allowing confidence to decrease in precipitation forming within this update. However, we will continue to monitor trends through Saturday. If any precipitation manages to overcome the dry layers, it will likely begin as drizzle before transitioning to freezing drizzle/sleet as temperatures drop below freezing. If this is the case, a few tenths of an inch of accumulation (primarily on elevated surfaces and bridges) could occur. However, increased winds and a relatively warm ground should prevent significant slick spots on roadways.

As stated previously, our largest concern is the very cold temperatures forecast to accompany the secondary cold front as it pushes through Saturday night. Lows Saturday night are forecast to drop into the mid 20s with post-frontal highs on Sunday remaining in the mid to upper 20s through most of the area. Due to the elevated winds, wind chill temperatures are forecast to be in the single digits Sunday morning. Be sure to bundle up in multiple layers if venturing out Sunday and limit time outdoors. Additional cold temperatures are forecast through Monday before a gradual warm up through mid week. More on that in the long term below.

LONG TERM

(Sunday night through Thursday) Issued at 943 PM CST Thu Dec 11 2025

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.

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

(12Z TAFS) Issued at 536 AM CST Fri Dec 12 2025

Gusty WSW winds will develop this morning and persist through the day, gusting to 15-20 kts through the late afternoon. Winds will weaken to under 5 kts or less after sunset, with SCT to BKN decks of cirrus passing overhead through the period.
