NEAR TERM

(Tonight) Issued at 207 PM CST Fri Nov 28 2025

No changes from the previous forecast have been made with this update. Temperatures this afternoon have warmed up into the upper 40s to around 50 in NW AL. High cirrus clouds continue to stream in from the west, but will have no impact to the local weather forecast.

Previous Discussion: After a chilly start across the area in the mid 20s, sunshine this morning has gradually warmed all locations above freezing as of 9am. Through today, an upper level trough will continue to shift east. The Tennessee Valley sits on the western edge of this trough and as a result CAA from NW flow aloft will keep temperatures on the cooler side today despite ample sunshine. Afternoon highs are forecast to top out in the mid to upper 40s, which is around 10 degrees below normal for this time of year. Tonight, clear skies and light winds will make an ideal setup for radiational cooling. Temperatures once again will drop below freezing with overnight lows bottoming out in the mid to upper 20s.

SHORT TERM

(Saturday through Sunday Night) Issued at 931 AM CST Fri Nov 28 2025

As we head into the weekend, an upper level trough will dig down across the Rockies and move eastward across the Plains. At the same time, a short wave along the southern stream upper jet will push across TX into the Tennessee Valley by Saturday afternoon/evening. This will bring a brief window for weak WAA as the sfc flow shift to more southerly ahead of this system. Afternoon highs on Saturday reach the lower 50s. Rain begins to spread from west to east Saturday evening with high chances for precip overnight into Sunday morning. The aformentioned upper level system ejects across the Great Lakes region on Sunday with a trailing cold front that will stretch across the Ohio Valley southward into the Tennessee Valley. The front pushes through the local forecast area by midday on Sunday ending the rain from west to east. Colder and drier air moves in from the NW by Sunday night resulting in another cold night with lows dipping into the mid 20s.

LONG TERM

(Monday through Thursday) Issued at 902 PM CST Thu Nov 27 2025

Our main feature to watch in the long term period will be an upper level trough and subsequent sfc low swinging northeastward through the southeast U.S. Ensembles are generally agreeing on the presence of an upper level trough shifting into our area, bringing widespread shower chances through the TN Valley on Monday night into Tuesday. No strong of severe storms are forecast with these showers as instability looks extremely low. The aforementioned sfc low is forecast to continue NE, out of the area, by Wednesday morning with sfc high pressure pushing in from the west. While previous model runs were hinting at some freezing rain potential in southern middle TN, recent guidance continues to trend drier with model soundings when temperatures drop below freezing on Tuesday night into Wednesday morning as the sfc high pressure influences the area. Wednesday and Thursday are forecast to remain mostly dry-- with low confidence, low rain chances pushing back into the forecast by Thursday evening ahead of another low pressure system. Highs during the long term period are forecast to be in the 40s-50s with overnight lows in the 20s-30s.
