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...

Looking closely at the GFS/ECMWF and honestly the pattern isn't that far from going from stormy/AR and Mt. Snow, to significant Alaskan blocking and arctic air digging towards us. That 00z GFS/ECMWF was incredibly dynamic just through Day 7 alone both spinning up a 950mb low! That trough means business with the polar air colliding with mild southwesterlies and powerful jet segment rounding the base of the trough. If that were to trend further east and digging a bit more look out!!!! Night Shift 6z GFS in 2 hours 10 minutes

Not bad. Could be worse

33F here. I thought it might freeze tonight. I finally got around to draining and putting away the hoses for the year this morning.
