KEY MESSAGES

- Impacts from a major winter storm likely linger into tonight. - Bitter cold weather returns tonight and lasts through next week.

LONG TERM

(Tuesday through Sunday) Issued at 201 PM EST SUN JAN 25 2026

Active northwesterly cyclonic flow continues for the extended period as a deep upper low pinwheels in place over the northeastern North American continent. The passing disturbances will manifest at the surface as passing clipper systems which will constantly reinforce the arctic air mass in place across eastern Kentucky.

Weak warm advection is expected Tuesday ahead of a clipper system that grazes the area to the north, with highs recovering into the 20s to lower 30s. Renewed flurries and light snow chances are expected within the favored cold advection upslope region in the Big Sandy basin, particularly Tuesday evening.

Another stronger clipper system will likely bring more widespread light snow and thus minor snow accumulations Wednesday evening into the overnight, particularly from Pike County extending west and northwest along the I-64 and Mountain Parkway corridors. NBM probabilities for measurable snow in this corridor range from 45 to 70 percent and probabilities for 1 inch or more snow accumulation range from around 20 to 40 percent, highest in eastern Pike County.

An additional clipper system will likely bring another round of flurries and light snow showers later Friday into Saturday.

Each clipper system will bring a refresh of the arctic air mass in place, resulting in a long spell of continued sub-freezing temperatures. Model trends suggest that temperatures bottom out Friday morning, with another round of cold weather headlines likely late week into the weekend, before a potential gradual moderating trend into the next week.

AVIATION

(For the 18Z TAFS through 18Z Monday afternoon) ISSUED AT 1219 PM EST SUN JAN 25 2026

IFR or lower conditions are expected into this evening as a major winter storm gradually exits the area. Rain and freezing rain will transition back to a brief period of wintry mix then all snow toward 00Z as cold air wraps around the system and drops temperatures. A very gradual improvement in categories is expected toward 12Z, with only very slow and gradual improvement at the very end of the TAF period.

Light winds currently will transition to a northwesterly wind at around 7 to 12 kts as arctic air moves back in starting later this afternoon into this evening. These winds may diminish slightly through the parts of the TAF period but will gradually back toward the west through the end of the TAF period.
