Damn. Not what I wanted to wake up to.
-
3k was still a huge jump north and expansion of the precip field
-
Models fully account for precip evaporating or subliming during descent.

Seems like with the 18z runs we finally have some consensus, it’s just consensus on dusting-1” for the majority of us instead of the 1-3” we were hoping for. That shortwave is trending stronger so maybe we can juice this up some more. Or rely on 20:1 ratios??

18z rgem was also north. It more clearly is loosening the confluence vs recent runs. Can we sustain some positive trends for more than 1 cycle now?
-
And much juicier down south. @Bob Chillgonna need to put the plow on his tractor.
-
Click through the previous 5-6 GFS runs and you can see our shortwave gets much sharper and better defined. Confluence is bouncing around more, which isn’t surprising from a more poorly sampled region.

18z icon an ass hair north of 12z. Basically dusting for most of the area. 1” down by EZF. 2-3” for RIC.
-
18z NBM is north relative to a lot of what we’re looking at it seems
-
Don’t know why, but I’m feeling really invested in this one lol. We don’t get many chances for cold powder daytime snows, let alone in December. I want something Friday!

-
A freezing or sub freezing high temp for DCA would be incredibly impressive. That’s like a -20F departure or more.
-
Well you’re looking at snow depth 2 days later?
-
Lock that max total stripe in right there!!
-
Another potential warm up cancelled?
-
First time in months that the euro ejects a southern stream wave faster than other guidance. Same pieces are there, just much more separated than on the gfs.
-
AI keeps temps in the 20s all day Friday.
-
Euro AI is a slight bump north for Friday. Dusting-2” for metro area. 3” for @Bob Chill, 2-3” for RIC.
-
GGEM closer to something early next week as well.
-
If the snow stopped at the Potomac like 12z gfs shows, I’d get pretty ragey…
-
Think I had a few pingers when it got started around 430, based on the sound on my windows? 34 and rain now.
-
Howard 2hr cold rain delay. And the kids rejoiced!
-
Baltimore and Carroll also 2hr delay
