6" snow depth in southern PA on the 03z RAP Models really moistened up tonight. 4" is looking more possible here, if I had to make a guess I'd say 3-3.5"

I'll stay here for the time being Dont really see any substantial cool down ,even tho you can see troughs going through East Asia which could cause the pattern to reshuffle more or less but its getting effected by other teleconnections,that Aluetian blocking isn't moving by the EPS OR GEFS, maybe it will change in future runs,but really no signs this is gonna happen anytime soon.We have a better chance of severe upcoming the next couple weeks after this cold snap

Gfs AI was 2 inches to the pike region.

00Z HREF mean is pretty close to the Euro idea...max is in same zone where it seems to want to go like Dover-Monmouth for the highest amounts https://www.spc.noaa.gov/exper/href/?model=href&product=snowfall_024h_mean&sector=ne https://www.spc.noaa.gov/exper/href/?model=href&product=snowfall_024h_max&sector=ne

You know it.. Here come the comments Sign here Lock it up Give me that and call it a winter The big ones are sniffed out early. It all is coming.. Until Dr No or the next run. Lol

Euro trimmed back too on the runs today.

Gfs with the Christmas Miracle again. Start a thread!

I went with 2-4” yesterday for our area and I’m making my final call tomorrow morning. I’m pretty sure I’ll be sticking with that. I expect closer to 2” for most of the area but I can’t rule out banding upping totals to 3-4” for some people.

What’s the latest NBM blend looking like @CAPE

High res > Ukie for this setup for sure

Snow on beaches is very cool. I just can't chase to Falmouth this weekend.

Jackpot over my house on that one

This could end up a warning event somewhere between Montauk and Provincetown.

It sucks with temps IMO. I’d rely on Euro/3k/etc for that at this point.

Thar she blows! What a windy looking map.

It seems to be the warmest model overall too. Now we can watch and see if any of the other models get warmer tomorrow, but if not...it could be on it's own. We actually haven't talked much about any potential temp issues...

UKIE isn’t exactly awesome at thermals. Given nothing else showing so much precip lost to rain, I’m gonna do a weenie move and toss the snow output and just look at the QPF

Ukie used to be a better model…it just seems to always be off the last few years. I’d trust the higher resolution models at this point. I do think DC will likely be just under 10:1 ratios.

The higher snow ratios maybe achieved north of South Mountain which could lead to a solid 3-5 inch snow event even in the LV if get good digging and upper moisture. South of South Mountain range will be more moisture acceptable so this is a tough call for the LV. The mesos are also having a tough time absorbing the digging aspect of this event -- the GFS was lost-- and the fact there maybe one hell of alot of virga throughout the profile until it collapses. We have a lot of cold dry air to overcome for this event to unfold. This storm event could easily become a debbie downer based on this fact, especially for those north of Philly.

Looks good for us though

Pivot has some rough graphics man

Ukie. Warmth in Metros kill accumulations. Don't like new Pivotal.
