NEAR TERM

(Tonight) Issued at 142 PM CST Sun Jan 25 2026

The back edge of the rainfall was now sitting from Winchester to Cullman and will exit our eastern forecast area by 21Z. The Arctic front was approaching the U.S. 43 corridor in TN into northwest AL and will sweep through the area quickly this afternoon into early this evening. Areal and small stream/creek flooding has resulted from runoff of the 2-3+ inches of rain which has fallen, especially during the past 6-8 hours.

The other weather impacts for tonight will be black ice development and gusty northwest winds, cold temps and wind chills. The gusty winds may cause additional limbs to topple that were impacted by ice accumulation in far northwest Alabama. Temperatures will rapidly drop into the u10s to l20s behind the cold front. A few flurries can't be ruled out, but measurable precipitation is not expected at this time. Expect lows in the l-m10s. Northwest winds gusting at 15-25 mph will lower wind chills into the single digits above and just below zero.

SHORT TERM

(Monday through Tuesday Night) Issued at 1013 AM CST Sun Jan 25 2026

The positively tilted upper trough from the Great Lakes through the southern Plains will drop southeast Monday into Monday night. Surface high pressure will follow south into the TN Valley and Gulf states. Very cold temperatures are anticipated as a result, with highs only in the 20s to around 30 Monday afternoon, followed by lows in the single digits Monday night. We have issued another Cold Weather Advisory for Monday night into Tuesday morning. Winds will be light, but will be sufficient to drop wind chills into the lower single digits above and below zero, especially for far northwest AL into southern middle TN. Full sunshine and slight warm advection on Tuesday will push temperatures into the middle to upper 30s for highs in valley areas. A few spots atop the higher Cumberland Plateau may struggle to reach above 32F however.

LONG TERM

(Wednesday through Saturday) Issued at 1029 PM CST Sat Jan 24 2026

Northwest flow will persist aloft through much of the long term period, with the passage of a shortwave shown on Wednesday. Another shortwave may traverse the Tennessee Valley by Saturday and bring a very low chance at some winter precipitation, but there is much uncertainty in global model solutions by that time. Surface high pressure on Tuesday will be pushed southward by a dry, cold front slated to move through the region on Wednesday. Little to no moisture is associated with this feature according to model guidance at this point. Thus, the main weather of note from mid to late week will be very cold temperatures, with the aforementioned cold front reinforcing these cold conditions for late week. Highs will struggle to warm past the 30s, with the coldest days being Thursday and Friday after cold FROPA (highs in the lower to mid 30s). Lows are also forecast to be frigid, in the teens throughout this time! Therefore, please make sure to dress appropriately for the cold weather. Remember space heater safety - keep the area around heaters clear (3 foot rule), plug them directly into outlets (no extension cords), and don't leave them running while you are away or sleeping. Protect people, pets, pipes, and plants!

AVIATION

(00Z TAFS) Issued at 636 PM CST Sun Jan 25 2026

Low CIGS and light drizzle/mist are creating MVFR to VFR conditions. Models are not handling well on how long this will persist, so kept current conditions in place for another 4 hours and obs will be monitored. Northwesterly winds will be gusting up to 20 kts through the TAF period and CIGS will slowly improve through the TAF period.

CLIMATE

Issued at 1029 PM CST Sat Jan 24 2026

High Risk for Much Below Normal Temperatures:

The Climate Prediction Center has included the entire Tennessee Valley in a High Risk for Much Below Normal Temperatures on February 1, 2026. Therefore, there is greater than a 60% chance for temperatures below 21-25 degrees F during this period.
