I plugged mine in last night before it started. It’s definitely doing it’s job for the gutters and leaders. Going to go down into the teens tonight, going to keep them plugged in.
27/12 up this way. Been holding there for the last few hours. Temps might drop off a few at the surface up this way too at the onset especially if the precipitation would be moderate to heavy at times.
At this point I wouldn’t ignore anything. Who knows how much the 800mb push will make it northward and what the surface temps will be. I believe most models are showing a sharp cutoff with frozen type precipitation and just might come down to looking at current observations during the event itself.
Still time for slight shifts one way or another. A 20 mile shift in either direction will affect many with that sharp cutoff. 18z runs tomorrow could have better ideas with the surface and mid level temps factored in with their placements and readings.
I don’t think we’ll have a real handle on this event even up to nowcast time. Also a definite possibility of a sharp cutoff area wiggling thru our region plus a mixed bag of precipitation types. A real toss of the dice IMHO.
