Snow update

5 P.M. Friday, Feb. 14, 2024

Forget much of what I said yesterday and earlier today. There’s been a development recently that looks like it’ll change the snow forecast.

The overall large scale picture remains the same, however, there’s a fly in the ointment. A wedge of dry air has appeared to our west and will push up the Ohio River over the next few hours. That will split the precipitation into two sectors – one north of the Ohio River and one to the south. Roughly 20 miles (or so) either side of the river will see less snow than earlier thought.

Another change is that we’ll probably see more sleet than expected. I had pretty much written off sleet as a brief interval during the rain to snow transition. Models are now pointing to a longer period of sleet. So, less snow.

Current thinking: We are now in a lull of precipitation due to that dry wedge. The sleet to snow transition should occur between 6 P.M. and 7 P.M. Any significant snow should be over by 8 P.M. and any lingering flurries will be gone by 9 P.M.

Snow accumulation for Louisville area should be small…up to one inch on grassy areas. Slick spots should develop (mostly) around bridges and overpasses.
