Bottom line, you can have impactful driving conditions with less than a tenth of inch. If you go out in the morning, take it SLOW! Moving north of the Parkways, the better bet is for a mix of sleet and snow. Generally speaking, most look to stay under an inch, but there are some hints of a narrow band of higher accumulations (1-2 inches) across the Bluegrass in the latest model runs.
Below is a link to each NWS office's briefing slides on the event. Again, this is NOT a major winter storm. We are not expecting any major power outages (maybe some isolated events), but travel impacts will be on the table. Take it especially slow on bridges and overpasses, which typically are the first to become slick!
Central KY - NWS Louisville
Western KY - NWS Paducah
Eastern KY - NWS Jackson
All of this activity will be moving out of the area by tomorrow afternoon. Unfortunately, this is the first storm of a few active days ahead. Two more weak disturbances will follow, each at least showing the potential for additional rounds of mixed precipitation, but nothing major. There's even the possibility we dodge them. Saying that, let's focus on this one first! Be safe, everyone!
