Don't push the panic button yet. The storm beginning late tonight/early tomorrow will bring a light mix of sleet, maybe a few snow flakes early on, then quickly change to freezing rain and then plain (albeit cold) rain. Nothing significant however.
I had held out hope we would see something more significant winter weather-wise, but we are lacking any good source of cold air; both near the surface, and especially aloft where temps are going to be too warm in the typical snow-flake (dendritic) growth zone. I'll try to post more details later.
Expect the NWS to issue a Winter Weather Advisory covering the overnight until around 10AM/Noon tomorrow.
