Models looks cold in NW Canada to end the month and open up December. Also a signal for AK blocking. Put two and two together, and we have a real shot...
This is something to watch. 522dam low level thickness and a CZ right overhead as night falls. First flakes of the season for Seattle? Could mix to sea level with the freezing level below 950mb.
It's nice to have real active weather again with all our longtime members back and posting. I think this winter's gonna be a fun one, especially if you like meteorology, not just cold and snow...
