Ok lets be real....we arent losing the trof in the NW US anytime soon are we?

With the PNA dipping even further negative, it’s likely that trough will persist, and there will be some ridge either over central US or east US. Even if northeast remains colder than average, with the rest of the country torching, there’s no snowstorm that can make its way over here. Unironically; the winter weather across CONUS this month could be the most significant of this entire winter.

I mean January is 2 weeks away, prime climo window starts in 4 weeks. Could it turn around by then and the models won't pick up on it until it's closer?

Potential dusting/snow tv on the 23rd on the GFS. That window hasn't really lived up to my interest in it, as the heights to our west just became too hostile for something to really develop even though we still managed to scrape some cold out of the situation. But flakes would be nice.

Honestly there's no chance until next month based off of what I've been seeing.

I think you’re right. You should probably sign off until then.

Question is will the tune change 2 weeks from now or will forecasters string us along with "not too late" pieces until it's February and we're staring down a week of 70s?

[jayyy]

A couple of weeks of normal to slightly above normal temps and the winter is over speculation has already started.

Mid season form, folks. Mid season form.

Relax, y’all.

The PNA dipping and trough persisting is more or less a tautology. If the models end up spitting out a new solution w/o trough by definition the PNA will not dip further negative. 

[JenkinsJinkies]

ENSO thread says -NAO talk is jumping the gun and don’t expect any significant cold shots at the very end of the month…

[Weather Will]

WB latest EPS on PNA. Anecdotally, when I see the PNA at -3 or lower, it just can't get cold enough at our latitude for snow....but notice it bumps up to near -1 around NY week and the control actually goes positive.  At that point, a negative NAO could work some magic and pull some cold air down with the AO neutral and the WPO negative. EPO is not favorable NY week.

[winter_warlock]

Look at this forecast for the mountains of Washington State!!!

 I'd love to have this forecast!!!!

 

[psuhoffman]

This is pretty perfect pattern for skiers.  Gonna be good for New England and most of the west from Colorado north.

I'm planning a trip to the Tug Hill towards the end of January. They lost most if their snow last night after a great few weeks. They closed the trails until further notice. Not good. I was hoping to deep snowpack. I see a bunch of rainers on the gfs over the next 10 days.

I talked to Mother Nature and it appears she's gonna wait for me to come back from FL on the 2nd.   Sorry guys.  But I did negotiate for a huge storm next month, so there's that.

Been quietly thinking the same thing. Taking my adult kids to my old stompin grounds in Summit Co, CO Jan 8th-15th. They had an abysmal start this year. I have some friends still living there and they said I used my snow shovel before them lol. They said it's the worst start ever and they've lived there since the mid 90s. Thankfully that's changing quickly.

Should have known we were in trouble when JB got all cocky and made his Sistine Chapel post yesterday.

We wouldn’t want a cold stormy pattern without you! Have a great trip. Catch some rays. Work on your tan…

[Terpeast]

I know the mood is in the gutter and the pattern is literally shit with little or no signs of recovering, but weak nina winters tend to be very volatile and I would not at all be surprised to see the cold east making a big comeback mid Jan through early Feb.
