KEY MESSAGES

Updated at 954 AM CST Sat Dec 27 2025

- Above normal temperatures will continue through the weekend and could tie or break record highs on Sunday.

- High chances for rain will move in early Monday as a strong cold front moves through the area with a very low chance for strong storms west of I-65.

- Much colder temperatures move in on Monday with wind chills dropping to the low teens early Tuesday morning.

NEAR TERM

(Rest of Today and Tonight) Issued at 954 AM CST Sat Dec 27 2025

Dense fog that formed this morning has since dissipated through much of the southern middle TN area. However, some lingering patchy fog exists throughout northern AL as well as in southern middle TN. Continue to exercise caution if traveling this morning. As sfc high pressure resides in the Gulf, southerly flow continues to influence the TN Valley. In turn, moisture and subsequent cloud cover forecast to remain in place over the area through the weekend. Highs today are forecast to reach the low 70s before dropping back down into the low 60s overnight. Patchy drizzle cannot be ruled out this afternoon (similar to yesterday). However, no significant rainfall is forecast today or tonight.

SHORT TERM

(Sunday through Tuesday) Issued at 954 AM CST Sat Dec 27 2025

Our main concern in the short term is a cold front forecast to push southeast through our area early Monday morning. Ahead of this, the Storm Prediction Center (SPC) has placed portions of NW AL in a Marginal risk (level 1 of 5) for severe weather- with the primary threat of damaging winds. Recent model runs have trended toward less instability available for any severe storms to form, however, cannot rule out a strong storm bringing gusty winds up to 50-60 mph as sufficient wind shear remains present. Lapse rates are also insufficient for frequent lightning, therefore, a low chance of thunder will exist. We will continue to monitor these trends through tonight.

Additionally, ahead of the front, gradient winds are forecast to increase beginning Sunday afternoon and continuing through Monday night. Gusts up to 25-35 mph are expected, with the higher end primarily being in areas of higher elevation in NE AL and southern middle TN. Behind the front, skies are forecast to quickly clear out and the sun should return Monday and Tuesday afternoons. Despite the sunny conditions, post-frontal temperatures are forecast to plummet into the 30s-40s for highs and 20s for lows. Be sure to bundle up early next week- wearing multiple layers and limiting time outdoors.

The last (and least impactful) thing to keep an eye on is whether or not we reach record highs on Sunday. Current high temperature forecast calls for temps in the low to mid 70s. The HSV record is 74 degrees (1907 and 2021) and the MSL record is 75 degrees (1907).

LONG TERM

(Tuesday through Friday) Issued at 900 PM CST Fri Dec 26 2025

Mostly zonal flow will transition to northwest flow aloft as a transient shortwave moves over the Southeast on Tuesday. This northwest flow looks to largely persist through late week; however, a decent amount of model disagreement occurs by Friday. At the surface, high pressue builds into the region from the west for much of the week until a cold front is shown to sweep over the Southeast Thursday/Friday. Overall, this pattern will lead to a mostly dry forecast through Thursday. Our next chance at precipitation looks to then come Friday/Friday night with the passage of the aforementioned cold front. There is the potential for wintry precipitation as temperatures fall below freezing Friday evening/night. With that said, it's still too early to decipher any details, especially with the amount of model disagreement that exists currently (greater uncertainty). Stay tuned to the forecast as we get closer!

In the meantime, the most significant weather of note will be the cold through much of the work week. Highs are forecast to struggle to warm past the 30s on Tuesday, with lows dropping into the lower 20s that night. An ever so slight warm up is slated for Wednesday, with highs in the 40s and lows in the mid to upper 20s. This appears to be short-lived as temperatures plummet right back into the upper teens to lower 20s Thursday night followed by highs merely reaching the upper 30s to lower 40s on Friday. Since it's been unseasonably warm recently, please do not become complacent - winter is still here. Remembering cold weather safety is imperative! Remember to protect the 4 Ps: people, pets, pipes, and plants!

AVIATION

(18Z TAFS) Issued at 1126 AM CST Sat Dec 27 2025
