Pattern Dazzling December

Absolutely love this trend. Connecting/ phasing some Arctic energy in Canada to our big cutoff means a stronger cutoff and and longer lasting deep cold low over the Eastern US-great lakes, this allows more Arctic cold air to funnel in as well View attachment 125495
Agree and the operational Euro is showing the same trend.

Not all of this will actually fall. Not all of this will still be on the ground. And with a little luck, perhaps we can extend this SE a bit. But, I'd say the N. American snowpack will be mighty healthy ahead of any artic intrusions that come near and beyond Christmas.

If we can build that snow pack over MO, TN and KY that would be huge.
