2PM Saturday, December 12
The midday model runs are complete and all say that Wednesday is primed to be a wintry day across central MD. The GFS and the European models are showing a major storm across the area, but both also bring mixing issues to the 95 corridor so it’s tough to make a call right now on total snow accumulations. Both models agree that moisture will be abundant. As far as how much snow falls will depend a lot on what happens with Monday’s rain storm. We want that storm to pass, move up east of New England, and strengthen around Newfoundland to help push cold air down the coast.
Although it’s very warm today, cold air will be plentiful and move into the area late Monday and Tuesday. Again, it’s early, but precipitation should move in early Wednesday and begin in most areas as snow. After that, it’s a matter of how close the storm tracks to us that determines how much warm air gets brought in overhead, especially from the 95 corridor and points east. If I had to wager a guess right now, I think most areas west of the bay will reach Winter Storm Warning criteria, which is 5 or more inches of snow and sleet, but that’s an early, early guess. A small shift north and we get all rain, and likewise, a small shift south, we get more snow. Maybe much more.
I’ll update again tomorrow.

Let’s hope for that small shift south…hope all is well brother!
