Unlike years past, we have basically all of Canada below normal temps, so plenty of cold air hanging out to the N. If Canada were void of cold, pretty easy to figure out things are bleak. But with all of that cold air still around, I really dont think we are done yet. Whether its next weekend, the PD weekend, or maybe sometime in March, we are going to have at least one more trackable large event. That cold air need to go somewhere...hopefully it continues getting funneled into the lower 48.

There's really 2 camps for where that cold air wants to be dumped on the ensembles. The GEFS keeps the pac ridge along or just off the pacific coast through late month which would funnel it over the midwest into our area keeping us in the game but just needing some luck. GEPS/EPS/CMC-E all retrograde that ridge off the coast of the pacific and funnel the cold air into the west in which case means SE ridge for our area and early spring. GEFS has done pretty well long term this year but it's hard not to be pessimistic when all of the other guidance is pointing in the wrong direction. All going to depend on who is right with the MJO progression. A shift into 4 pretty much closes the blinds late month though it get's a little less hostile come March. Hope you're right that we get one more trackable event. Those of us in SE PA are really only 1 warning level event away from touching normal, I hope we can get there. A 2nd year Moderate-borderline strong Nina, that finishes with >20" of snow would pretty be abnormal. Honestly heading into the winter I said if I get into double digits, I'd be pretty content. We got there plus saw a warning level event and a high end advisory event so things definitely could be much worse like up in the Lehigh Valley.

Will determine our fate late month. Neither is particularly a classic look but we could still score something with the GEFS due to the cold air lurking nearby. If that gets dumped into the west like the other ensembles it's a shut the blinds look until March.

yep those pity flakes keep on falling. As I said before - Presidents day for the win. I see it on the models runs as they are choking on it now. They will get their act together in the next five days

No candy coating it our winter sucks. Need 19" to normal or another late February through early April early spring performance like 2018 to salvage numbers, or end with 1976 cold futility. It was oh so close to being a good one post December but the eastern North America trough was slightly too far east thus the big AC to NYC coastal score zone.

An unusual elongated and strong polar vortex winter, is was cold because the elongation axis pointed in this direction.

Trend should be milder times to close out February and the month of March.

I hope so, I'm ready to put this one in the past and move on to fishing season.

I'm not giving up on Sun night/Monday yet. ICON is a shitty model yes, but it shows how we can potentially win with this system. You look at 500 MB and the globals are all over the place with timing of both the NS and SS energy. This could be one that sneaks up inside 4 days as data is better sampled. Need that NS system to dig more like the ICON and the CMC to an extent. And need the SS to not hang back like the ICON. It's a fragile set up as Ralph would say because there is no blocking but there is still room for a snowy outcome. At the very least, may be able to score 1-2" on the N stream energy alone.

Beautiful day across the now snow less hills of Chester County....getting ready for the record elevation driven March wet snow event that will get my area to normal snow totals for the season. It will no doubt happen the week of March 12th when I head down to Florida for Phillies (or not) Spring Training.

Pipe dream.

May as well go to the mountains where you have a better chance at a late season snow...

35F/Breezy at times

It's like Morgantown (6 miles up the road from here) 1958 all over again - 50" in 1 day while Philly gets white rain....stay tuned - LOL!!!

long live that fricking donut hole. WE take this in the LV

 

Euro and ICON keep the seasonal trend...NJ shore special, LV fringed.

Delicate setup here all about timing of shortwaves. We are relying on forcing between the NS and stj late phase to throw precip into the region. I think we run the risk of this escaping quickly without any blocking much like the other systems this year. If we r going to get a flush warning level hit, we need a deeper dig in the NS, the stj sw needs to go negative by the Miss River or neutral at very best, and things need to slow down. There is time but need to see corrections over the next 48 hrs.

Agreed. Not that it's the same up top, but for now seems like best case end result will be a lesser version of 1/28-29 to these novice eyes. Again lots of moving parts and interactions that won't start to be well-modeled until tomorrow imo. Who do we have to speak to in order to get some blocking?! Is this still from our winter-for-Super Bowl sacrifices from '17-18? (Worth it)

We should never let facts in in the way of a good story....but the spirit is a lot of snow got lost without elevation to the dreaded white rain!!
