Almost every model showed improvement at 0Z for almost everyone near/along 95 from DC to NYC and even NW of 95 and the NBM shows NYC with >3" for the first time (3.1") and the NWS has responded with upping their snowfall map across the board for most, as well as increasing their WWA's to 3-5" for many areas from 95 to the coast and adding in quite a few counties for 2-4" of snow well NW of 95 and N of 78. It's been a good evening. Here is the updated NWS map and the latest NBM and the NWS WWAs. Getting excited.

WB 6Z NBM

WB 6Z HRRR looks good!

I believe that, especially since it’s still so early in the season, but it’s not just at DTW, the NWS and surrounding areas in the hills get more snow than Flint Bishop, MBS in Saginaw county, and probably Ann Arbor. It’s honestly what sparked my interest in weather growing up in southeast Michigan.

I'm pulling an all nighter, getting ready for the all nigher tomm night! 6z Hrr looks north, but a solid 4" here

After all this time they ain't updated those graphics? Lol

Yall sleep? Who can sleep the eve before the Blizzard?

Euro looks good. Don’t know how it compares to 18z. But 2-4 down this way. Similar precip axis like the others. SV graphics are made in Minecraft

I'm up at 2am 90% of the time anyway, so...yep!

Yep! I don’t need to get the jack on this one. Would be perfectly content with an inch or two refresher.

Why the hell not, I was all for starting a thread for a random date in winter and gassing it up for no reason

Bro go to bed

so anybody staying up until 2am lol

Models don't usually correct significantly when there is a PNA projected to be -2 to -3 for an extended period of time. Sometimes you will trend toward a better polar orientation (more -EPO), but that doesn't favor deep cold/snow, it just mutes the warmup.

f the Euro

Latest Lwx map now adv are up

In terminator we trust…”the snow will be baaack!”

Looks like WWA hoisted for you so thats a start! I'd rather be on the N side of the QPF axis. S side is gonna be a brutal cut off.

It would be pretty amusing if we come out of the cold period that was hyped up quite a bit with very little snow and then find a way to squeeze a legit snowstorm into this upcoming pattern

After bottoming out to 15 earlier, up to 21 now (in line with model/forecast).
