KEY MESSAGES

Updated at 959 PM CST Tue Dec 23 2025

- A strong cold front will move through the area on Sunday bringing much colder temperatures to the area early next week.

NEAR TERM

(Rest of tonight and Wednesday) Issued at 959 PM CST Tue Dec 23 2025

A low to mid level stratus deck continues to cover northeastern portions of the area and will continue to be the area of focus overnight as it will determine which areas fog will be more likely. With calming winds and clear skies across our western areas, have the highest confidence in fog west of I-65 and south of the Tennessee River but have added patchy dense fog across much of the area through the morning hours. Overnight lows will fall to the mid 50s across much of the area keeping our temps about 20 degrees above seasonal norms.

High pressure and westerly flow will continue to advect warm and dry conditions to the area on Christmas Eve with afternoon temps rising to the low to mid 70s. While we could see a few breaks in the cloud cover tomorrow afternoon, mostly cloudy skies are expected to continue into tomorrow night.

SHORT TERM

(Wednesday night through Friday) Issued at 959 PM CST Tue Dec 23 2025

Changes to the overall synoptic pattern through the short term period will be slow and minor, as high pressure shifts to the southeast and flow aloft becomes more zonal. Temps will continue to run about 20 degrees above normal for late December (normal highs in the low 50s, lows in the mid 30s) as afternoon highs reach the low to mid 70s both Christmas day and Friday. In fact, lows will be even warmer, only falling to the upper 50s in most locations. If the current forecast holds, we may tie or break record highs at HSV (73/2016) and MSL (73/2016) on Friday.

LONG TERM

(Friday night through Tuesday) Issued at 959 PM CST Tue Dec 23 2025

Saturday into Sunday will bring the last of the string unseasonably mild days as an upper ridge shift east as a deep upper low and trough swings southeast into the eastern CONUS. This brings a strong Arctic cold front through the region late Sunday afternoon and evening. A round of showers will occur with the front, although will need to assess stability trends as we move closer given the strong bulk shear. But at this time, no thunderstorms are forecast, but stay tuned. After highs in the lower 70s Saturday and upper 60s Sunday, the bottom drops out with readings falling into the 20s Sunday night. Highs will be held to the 30s Monday and Tuesday, with Tuesday morning lows in the teens. Blustery north winds of 10-20 mph are expected Monday, diminishing greatly Monday night into Tuesday.

AVIATION

(06Z TAFS) Issued at 1205 AM CST Tue Dec 24 2025

An area of VFR stratus was slowly advecting to the SE across the TN Valley. VFR conditions prevailed for most of the area. But before the clouds moved in, fog has formed over the KMSL terminal, producing 1/2SM VSBY. This fog may dissipate somewhat in the overnight as more of clouds move in, but confidence level on when this could occur is low. Fog should dissipate after sunrise with daytime heating and more mixing realized. Model trends however indicated that stratus should remain over the area through the afternoon. Indications are the cloud bases should remain above 3kft, but some MVFR lowering cannot be ruled out.
