We’re still on track for accumulating snowfall tonight. The greatest factor in how much we get depends on how long it takes for the ground, etc. to get cold enough to collect the snow. It’s going to snow. That much is certain.
The advisory is for 1-2″, with isolated amounts of up to 3″ around and north of Jamestown. That’s not how much will fall in total…that’s how much we expect to accumulate. Much more may actually fall. This system has a good bit of moisture with it and we’re going to get some hefty snow showers tonight.
The temp is currently 46 degrees here at TAP in downtown Crossville, but the temp is already 43 on TN Tech’s campus (and dropping). Our temp will be dropping shortly.
Each model run has trended heavier with the snowfall, but again, it’s not a question of us getting snow, it’s a question of how fast will the ground get cold enough to collect it? Notice it really shows up on the plateau, and also in the mountains on this latest model run.
Remember, the winter weather advisory goes into effect at 10:00 p.m. tonight and expires at 10:00 a.m. Wednesday. These upper-level low systems are very tricky to forecast. Honestly, they make me nervous, and they’re notorious for surprises. Fortunately, models have been consistent on thinking that we’ll get an inch or two. Over in the mountains they could get 6-10″.
The current radar (3:15 p.m.) shows the snow coming into western Kentucky.
I’ll be watching it all evening, and I’ll let you know if anything changes!
