The -PNA is fading but so is the -NAO…Not seeing anyone pointing out the latter… I don’t know why these phases have been in sych in recent years but it continues… As for the CPC forecast beyond day 10, I think the +AN risk is greatest along the east coast losing the -NAO, and with the west coast ridge axis being west of Washington state… It’s a long wave pattern where upstate NY into northern VT can do very well, snowfall wise. The whites of NH into northern Maine as well…latitudinal Gradient vibes returning to New England. This means a poor pattern for sig snowfall chances in the major metros from Philly to Portland.

I’d sell my house in a heartbeat if the current pattern was the norm around here. Trash.

Looking more and more like a week-ish of suffering through dry and significant cold to a warm up and cutters. Then we evaluate if the warmup is an interlude or a new pattern…

sure. Buts it’s crap odds at this stage. Low end advisory or a big cutter if it phases. It has the hallmarks of another big cutter.

Warm. That one is pretty well screwed. If it phases with the northern stream we’re cooked.

You could not draw up a worse pattern than this. Significant cold and no big storms. Miserable unless you’re a hermit.

Plot twist: 6th is a very big storm, but it’s another cutter that ushers in a crap pattern. Question to be answered is if the hostile pattern sticks.

“Pattern shift….” Careful what you wish for. There’s some naive optimism in seeing less mid level troughiness on the west coast but this is not without losing cold anoms in Canada. After first few days of January risk is tilted warm, even in the northeast. There’s some indications also, that the MJO makes a pass to 4/5/6 which are all warm phases for Jan. Pattern looks like trash around hr240 on the ensembles. Deluded to be getting excited for big snow from day 9ish on..

January 6th system is warm. CONUS and Canada cooked. It will want to warm sector where most of us live. You’re making a bad bet on hoping for this to turn to a big snowstorm.

The HRRR is way too cold vs all guidance, tonight. No reason to buy that with the clouds moving in after sunset and torching above the surface starting by midnight.

Freezing is a warming process. Temps will spike quickly to 32 everywhere except the valleys of NNE.

Looks good. Liking the 0.25 contour cutting through DAW. Another case where Rochester has a lot more icing risk than my hood just 10 miles SE. I could see DAW getting 0.25” but my backyard getting less than 0.1”. We’ve had a number of events with very favorable atmospheric icing conditions but a degree or less saves us from disaster. Not the case just 5 miles to my northwest…

I think the sig icing risk is confined to the valleys of NNE. Atmosphere is warm just above the surface…
