Colder air brings some snow
While most of the weather talk today concerns the minus 10 to 20 degrees below zero wind chills expected tomorrow morning, the models are getting a little friendlier toward the cold blast bringing some snow as well.
It won’t be much, but at least we’ll probably see some actual snow on the ground by morning. The GFS likes the idea of a bit of snow. The NAM, not so much. Both of the short term (24 hours or less) models, the HPPP and RAP like the idea a lot. The latest blast of Arctic air will arrive this evening. From roughly 9 P.M. until 1 A.M. some light snow/flurries will accompany the cold air. Accumulations along and north of the Ohio River should be from a dusting to a half-inch. South and east of Louisville will probably range between one-half to one inch.
In any event, the winds will be over 20 mph tonight, so the snow will be blowing around a lot. Roads will see most of the snow blow off. If crews put salt on the roads, it will make matters much worse – lots of icy spots.
Temperatures will bottom around 5 degrees tomorrow mid morning and only reach the lower teens tomorrow afternoon. Most of us will see near zero temperatures Thursday morning.
Another chance for light snow arrives Thursday night.
