Interesting it shows an AK vortex but still ridging over the west coast. Probably because it is pos tilted. Orientation matters.

Yes, a trough over Japan is always preferred!

Lock it in for Friday.

I like this possibility.

It's early! But definitely intrigued by next weekend. Compared to say, Tuesday, it is looking like a little better chance for the DC area. It's not perfect but again, it is a week out it doesn't need to be yet. Pattern wise definitely like that both -NAO and a 50/50 low are showing up in a lot of the modeling. Again, not perfect...the west could be a lot better and NAO could be more west based...but these are both features we are lacking with Tuesday so them showing up is a good start. Also of note is the Southern Oscillation Index, or SOI. One of my college professors loved the teleconnection that a sharp SOI dive was well correlated with East Coast storms. Well the SOI is forecast to take it's sharpest dive in at least 4 months around next weekend. So something interesting to keep an eye on!

Always we need to wait til we have very established cold to have a chance. With a warmer base state due to climate change I feel like hedging towards warm sloppy mess for the metros makes sense, especially early season.

That model has not been good at the surface.

Can someone post the Eps AI snowfall total for the entire run? I have Pivotal and for some reason doesn't have snowfall amounts from that one despite the other info. Maybe it doesn't want me to go blind, idk. Anyway, Tia.

That looks consistent with yesterday's I believe, or the day before. But, consistency does not prove accuracy in this case.  Although maybe the ensembles here are better than the AI model itself.

Active and cold =   I can dream.

Nice influx of cold this week, that's for sure.

I keep checking bluesky to see whether HM ( aka Anthony M. )  posted any updats regarding his December weather thoughts.  Not seeing anything. I know someone posted a while back he was enthused for this Jan.

Not by early December standards.

Okay this winter is getting really old really fast. The 500mb pattern is so flawed. Highs can’t lock in. Weak southern stream. The is no ridge on the west coast. Flat progressive flow. Fantasy storms disappearing. Real storms string out
Phase 8 my as$
