KEY MESSAGES

* Winter storm system will bring a wintry mix of snow, rain and snow, and for some all rain today into this evening.

* Winter Weather Advisory is in effect for the potential of a narrow band of accumulating snow today along and north of the I-64 corridor. 1 to 2" of slushy snow accumulations could fall north of I-64 with a coating up to 1" of snow right along I-64

* Main impact could occur during the afternoon and evening commute.

* Below normal temperatures through the weekend.

..Overnight

As the system moves off to the east later this evening and overnight, model soundings show low-level saturation below the DGZ. This could produce a period of drizzle and possible freezing drizzle overnight. This will need to be monitored closely as temperatures will quickly fall into the low/mid 20s as we go overnight into tomorrow morning.

LONG TERM /WEDNESDAY THROUGH MONDAY/

Issued at 404 AM EST Tue Feb 3 2026

General troughing pattern will hold across the eastern half of the CONUS through the end of the week. This will continue to keep us locked into a colder than normal weather pattern thanks to persistent NW flow aloft. Another embedded system through the upper level flow could move through the area by the end of the week. After temperatures into the upper 20s/low 30s for highs Wednesday and Thursday we see temperatures try to warm into the 40s by Friday. This system compared to today storm looks relatively weak with very little overall impact. Will continue to mention rain/snow showers. Once this system passes, we return back to colder weather with high back into the 20s and 30s as we go into the weekend, with another warm-up Sunday into Monday.

AVIATION /12Z TAFS THROUGH 18Z WEDNESDAY/

Issued at 649 AM EST Tue Feb 3 2026

Two systems are expected to phase over the area today with conditions and flight categories deteriorate through the day into the overnight.

For HNB, SDF, LEX: wintry precipitation in the form of mainly snow, but some rain and sleet are possible. CIGs and VIS will fall to MVFR over to IFR and even periods of LIFR. Lower with potentially heavier snow bands later this afternoon and evening for SDF/LEX mainly around 21-24z. The other potential concern is drizzle and even freezing drizzle overnight with low level moisture trapped near the surface and low CIGs and VIS.

For RGA/BWG, precipitation falls mainly as rain and then a period of drizzle and even freezing drizzle overnight around RGA. Similar as above with lowering CIGs and VIS to MVFR, IFR and even LIFR.
