KEY MESSAGES

- A brief warm-up will last through Tuesday, with colder temperatures then returning and lasting through early next week.

- Rain is expected on Wednesday with the transition back to colder weather. Remaining precipitation changes to snow for most places Wednesday afternoon and evening, with any snow tapering off Wednesday night and Thursday. Light snow accumulations are expected, especially in southeast Kentucky.

LONG TERM

(Wednesday through Monday) Issued at 405 PM EST MON JAN 12 2026

Transitional weather will occur at the start of the period, with a deep upper level trough developing over the eastern CONUS. The associated cold front will pass southeast through KY during the day Wednesday, with upper level support from the trough and associated jet resulting in rain. A transition to snow should also occur as colder air arrives behind the front. Models have not come into strong agreement yet on timing of deep moisture departure and arrival of colder air, but have generally trended toward lighter snow accumulations for most places. A transition from stratiform precip to snow showers should occur as drier air arrives aloft and low level lapse rates steepen in the arriving colder air mass with upslope flow. The best shot at accumulating snow is in southeast KY on Wednesday evening. A brief enhancement from connection to flow over Lake Michigan can't be ruled out, but details on this are likely to change yet. Low level moisture eventually gets eroded and dry weather should return even in southeast KY by Thursday evening.

The upper trough will remain over the eastern CONUS through the remainder of the long term period, keeping our temperatures cold. Impulses/vorticity maxes will rotate through the trough along with reinforcements of colder air and be the main factor in our day to day weather. However, models show less agreement (more uncertainty) in how this plays out the further out in time that you look. There could be some light precip at times (most likely snow), but confidence in timing is not very high.
