Long range GFS is very interesting... Okay not very, but it at least through us a bone. Dry and chilly.

I'm happy some of our weather geeks up north are seeing some snow and even snowy fun. Enjoy it. It's windy down here and about to rain. 12z runs/ensembles just.... It's hard to be very encouraged. I will look forward to the dry, cold east winds though. At least there's that. Maybe I'll take a vacation.

18z Euro coming out and it appears too warm at the surface for 4PM.

Shows Seattle sitting at 52 when really they are sitting on either side of 40 per Wunderground stations.

That's automatically wrong for me. It's 38 here in West Seattle. The NAM 18z said it should be 52 degrees right now.

Way too warm up here as well. I’m at 34.5, that says I should be at 37.

Elevation 580’ Location a few miles east of I-5 on the Snohomish Co side of the Snohomish/Skagit border. I love snow/cold AND sun/warmth!

Have a good vacation. Remember winter may start in December, but real winter weather in PNW waits til February these days.

There's a joke in there somewhere.

LOL she has a 4WD Honda Pilot with the triple mountain/snowflake tires on them, but she also has to get on the freeway to get home (which she hasn't had to do before.)  She hates the freeway when its clear and dry.  She's stressed as hell with the holidays, so it may not be a good mix.  I've got proper snow tires on my car, and am much more comfortable driving in the snow.

And late February at that. Besides ‘13-‘14 and ‘16-‘17, it seems to have been late February and March. Would really like another arctic blast around the solstice. Nothing like low sun angles when there’s snow around.

Looks like 925mb and 850mb temps are fairly close to what the 18z Euro progged for 4PM. A degree or two colder but nothing way off.

Seems like the surface temps are what's running ahead of schedule.

I'm not convinced that spc upper level temps are matching what's actually going on. I think some of that output comes from the RAP model.
