Thanks for pointing that out. The 12k and 3k might as well be two different models. May sound like a weenie, but I’d lean more on the 3k within 48 hours of onset.

From the POV of NWS, their mission is to protect life and property. Given a difficult call between forecasting a few inches of plowable snow/sleet and a devastating ice storm, where it could really go either way or have both in the same region, I think they would rather warn people of the worst case scenario. Because if they don’t, and the ice storm happened, that would be a mission failure on their part, and it may cost people lives and property. Yes, there is also risk of a busted ice storm forecast in the eyes of the public, but that would be preferable over the former scenario.

So that’s 4z-12z or 8 hours of snowfall before the flip.

When JB posted that, he just guaranteed the bullish gfs scenario isn’t gonna happen. Thanks a lot JB!

That would be welcome news for S VA if its mostly sleet instead of zr.

Looks realistic tbh, can’t say I have anything to pick at against

Minimum 12 hours of snow for DCA before flip, with progressively increasing intensity.

I was hoping to see some more consensus with either gfs caving to other guidance, or both sides meeting in the middle. But they could not be further apart. We may have to wait until 0z tonight to see where this is heading.

They may be going with a blend of the Euro and GFS. Which isn't entirely unreasonable, just not something we would run with ourselves.

I’m right on the navy blue line just NW of IAD, and 7-12” is consistent with what I was thinking.

10” would be fantastic!

Also think of it this way… we’re finally getting a classic N&W storm

If I can beat my 7.6” in last year’s storm, I’m good.

I think a blend gets us to 6-10" DC metro, 8-12" NW, 12"+ out up in WV panhandle through PA SE of DC 4-8" with lots of sleet, and south of EZF start to see icing (subject to change ofc)

It was awesome. Started out raining briefly, then flipped hard and the rates - oh man. I stayed up the whole night. Worth the sleep sacrifice.
