I don't want to clog up the Medium/Long range disco with extrapolation of the "unicorns are real" time frame of the 12z GFS, so I'll post here.

 

It's cold after Christmas... really cold. But first it shows a seasonable Christmas day with highs in the upper-30s/low 40s. The coldest day appears to be 12/31/14, with highs in the upper-20s and lows in the low 20s. For some reason the lows don't look too impressive. The coldest lows through the run are only around 20F in the NW 'burbs. I'm not really sure why that is.

 

Anyway, it looks cold, and DCA/IAD/BWI should record their first sub-freezing highs of the season before the new year.

I'm a glass half full person. Looks like we'll almost get snow several times this month. Some Decembers we don't almost get snow at all.

You'd love living in the city. We almost get snow a lot in the winter.

Right now I don't like a single model for the next 10 days.

Not sure you can totally write off the Christmas eve event given its pretty dynamic and looks like an Archambault event but not looking good.

I should look at the LR GFS more often lol. 18z shows extreme cold in late December. Upper-teens/low 20s for highs, and lows around 10F. Then at hr 384 the cold leaves the area, but another icy blast is coming down from Canada into the Plains.

 

Sweet.

You know me and I'm not. Very potent setup for sure and we'll get a lot of looks. I could see some stream separation and different timing letting something cool happen.

Assuming the gl low exists in some fashion, there's a decent airmass in front of it and behind it. I could envision sne getting hammered with a transfer of some sort too.

Agreed.  Hard to envision much more than flurries/SHSN with the big Xmas eve storm for us and then signs of a cutter for Boxing Day/27th.

It certainly looks like an Archambault event, but hard to see how it could turn into an all snow event for us.  12z Euro was about as close as I've seen with the main 500mb low digging so far south, but it would need to dig even farther S/E.  Windy and cold for Xmas is better than warm and sunny to me though.

It's still technically fall so....I got nothing. I'm starting to really think most of us won't have a storm this weekend or a white Xmas.

eh.. not really. yeah first 10 of march are better than first 10 of dec for snow.. but we have other issues that come to play then quite a bit around here.  if nothing else we're at least a few days into winter... ;)
