Ok, I’m trying not to get excited but you all are making it very difficult because you all don’t normally talk like you are about this one.

That can’t be real right?

The terrain of the eastern U.S. does a lot to slow the progression of those cold airmasses. The situation we're seeing tonight usually happens with very dynamic systems where the temperature drop is aided by very strong ascent and dynamic cooling.

My amateur theory was that it's because we have more humidity than the plains . . . which in reality is probably only a small factor.

OK, the other weird thing about this is that often when there's abrupt temperature drop in autumn/winter we have a period of gusty winds immediately proceeding a sharp line of rain, and then after that the cold air comes.

This isn't that.

There are other models showing similar accumulations but when you take into account melting and compaction of snow accumulations will likely be less than that.

I'm more interested in the model trends and it's a very good sign when the major models are all trending upward the night before the event. Normally for us they trend the other way lol. It's nice to see the Valley in the bullseye of one of these systems for once.

Wife is supposed to catch I flight a 7am tomorrow. Is this thing going to be an issue?

It's supposed to hit early tomorrow morning so it likely will be an issue.

Well I wish we would get 9+ but I’ll “settle” for 4. Dang, I sound like my wife.

If it's out of TYS, I'd think it might be an issue. Should start to lighten up by then, but I'd expect some flight delays are probable.

Yeah I prefer to look at the positive depth change in situations like this to account for the melting. Still significant accumulations and trend is up, up, up with totals.
