Novice here. How similar (if at all) is the setup January 26, 2011? I remember we had only marginally cold air but were able to overcome it quickly with an almost ideal lower pressure track and dynamics.

It's a bit of an apples to oranges comparison. 1/26 had a really vigorous and energetic upper level closed h5 low that tracked just about perfectly to our south. The dynamics easily overcame quite warm temps out in front.

The upcoming system is stream interaction with just some areas of vorticity at h5 embedded in a pretty fast flow. Nothing closed off or slow moving.

I'll take a 1.26 setup over what's headed our way anyday.

Take a look @ h5 vorticity between 12z and 18z from 72-90 hrs. They both show the 3 pieces energy spread out from the gl to the mw down to the se coast. 18z slows down the middle piece of energy and leaves it behind the ns and ss vorts. NS vort is stronger this run and pulls the phase further north and now we have an absolute terrible 850 track.

I know I sound like a broken record with this stuff but just run through the h5 vort panels. Very complicated. Slightest diffs in timing and strength = crazy swing is solution.

I don't have access to h5 vort panels for the euro so I can't compare. Did the 12z run show 3 pieces of energy or 2? My guess is 2 based on the ots solution.

SOmething has to give tonight I would think...either the EURO needs to come more in line with GFS or vice versca....Maybe a Met can help..if HPC said disregard the 12z run, wouldnt you disregard 18z too since its running on 12z data? If so who cares about it

HPC also said yesterday that in their opinion it wouldn't be resolved probably until within 48 hours of the event. I'm just the messenger on this one.

Wow if this run came true I'd love to be in a Cabin up in the Hudson Valley of NY, interior MA, or the Catskills with a pair of xc skis and snowshoes.

The hudson Valley is a bit of a snow hole. You'd be better off in the high terrain on either side. Hope this ends up giving everybody a good shot. Good Luck!!!

wunderground has the h5 vort panels if you want to take a look. The 12z run did have the 3 pieces, it just runs the great lakes one a heck of a lot faster.
