I would guess that @Jimmy Hypocracy likes this....stealing the PV and cold air from Asia, cross polar style

Trend on the big red ball looks amazeballs on the GEFS

What a beautiful day here. High of 50F expected under mostly sunny skies. Low of 27F. Snow capped mountains all around the city.

Wonder if that counts freezing rain and sleet as snow??

Here was the pattern surrounding Christmas '83 when compared to the LR EPS. Some noticeable similarities between the strong -NAO and +PNA. However, this pattern has a -NAO, but less of a SE Canada Vortex.

College dupage only counts snow but not sure about pivot. I think it’s just counting snow.

I wanna say Pivot doesn't, because they have separate maps for ice, but don't quote me on that

If You look the cold air is more expansive and the colder air fans out more and better. Better for the cold air to slide across than dive down. If this trough dives down we can kiss any snow bye-bye.

The other thing that I’ll point is that often when the cold air dives down hard like January 1994 for example, anything trying to come out of the southern stream get squashed to the southern Gulf or sheared out completely. Honestly,the January 1988 storm is a great example of how you want a cold airmass to come in.

Yeah euro isn’t as progressive as gfs/gefs with the TPV

The Euro is closer with the 102hr deal.

Don’t like this euro run so far, it’s taking it’s sweet time to get out of there

Yup, ugly in the short range.

MMFS has a decent setup around the 20th

We don’t have nearly enough cold air for that system to work I’m afraid

Out to 150 it certainly doesn't look like the 00z EPS, but perhaps it did take a small step in that direction? Greenland block definitely looks stronger.
