Cmc would have showed a huge snowstorm past 240.

Gfs miller A end of run

To show you how cold the air mass on Friday is, the 0Z RRFS-A has Boston on 12Z Friday with a temperature of 10 degrees with a dew point of six below zero.

We ended up with 1.0" of snow here in East Nantmeal this morning. This was our 5th winter event of the young winter season. The 10.4" of snow recorded this month here in EN is the snowiest December since the 11.7" of snow back in 2017. This is the 6th snowiest December in the 23 years I have been at this location. We get a brief reprieve from the winter weather through Christmas Day with afternoon temperatures just a few degrees below normal for the big day. Our next winter event looks like it could be our most impactful so far this season. Snow should arrive around noon on Friday we should then see a change to first sleet and finally freezing rain as we move through the afternoon. Temperatures during the storm on Boxing Day are likely to only warm into the upper 20's to near 30 degrees so what falls will likely be frozen in some form. We warm to near normal on Sunday before we turn much colder again on Monday and look to see below normal temperatures through the remainder of 2025 and into the first week of 2026.

Eventually, that will eject and get the entire CONUS, esp east of the Rockies.

Yes the GFS has hinted at that. Good to see the GFS come on board!

Now that is where ratios would be nuts!

Truly have lost count at how many times this has happened. 11-15 day model forecasts seem to be useless this winter.

That isn’t deep winter… That’s TUNDRA winter… like frozen Hudson! And a blizzard! Omg!

Good stuff guys

because I'm old I remember hearing Alaska was well below zero in January 1972...something like -50 or lower...that was around the 10th of January...Anchorage was -30...a week later NYC hit 5 degrees...this was a few days after 60 degree temps...
