Mid to late February Pattern Discussion...stormy or end of winter?

Out in clown range, but its amazing how that big plains storm at D9 runs into that block in E Canada and gets forced under SNE. Paste snow to perhaps a period of ice in itnerior (rain coast).

 

 

That's a high stakes storm...could be really good or could be wet.

 

Check out the weenie extended trough under the Hudson bay block that helps keep the flow from buckling. Considering how the day 9 euro op loves to be amped up..not a bad look.

Yeah I was thinking the exact same thing...Euro gets cutter-happy in the long range and it still got shoved underneath that block. Adjust even just a hair for that bias, and it would be a pretty sweet setup.

GEFS look very interesting in the LR. 12z caved more toward the Euro ensembles in the colder look..esp for our region. Look at that nice western ridge pop with the very stout positive anomalies in the west NAO region

And I have no problem with rolling a big event through the nadir of that trough over the east, either.

Euro ensembles bullish on the weekend and then again around Mar 1-2.

 

More of a risk in the Feb 27 signal...but certainly could end up snowier as well. Better signal for interior on that one as of now, but obviously a lot of time to figure out details.

Euro ensembles have between a half inch and an inch of liquid for the Feb 23-24 weekend potential...so certainly more bullish than the OP in that sense. Still too early to obsess over QPF but thought I would throw it out there.

I like the potential this weekend to halve what BOS needs for the record and then hopefully we get enough at least on the front end prior to 3/1 to seal the deal.

Yeah I think they'll need a good hit this weekend to get the record...I'm not that high on Feb 27 as of now for the coast, but that could def change. And of course, the Mar 1-2 threat is after the calendar turns so we can't use that one to get the Feb record (or monthly record) for BOS. 

 

Models will prob struggle a bit with this block. They often underdo how tough the cold air hangs in ad try to drive WAA too aggressively into it.

Well that's out in clown range at this point, Maybe i will score tomorrow night some, If the low develops slightly further south

 

 

Yes...though synoptically on a larger scale, it looks better than the Feb 23-24 threat for NNE. The trough has a little bit less resistance from the block which gets weakened some...then that 27th system tries to rebuild the block a bit as it passes. So there's a window there. Obviously being in clown it can change, but from the synoptic standpoint as good as we can tell at this range, that one would look better right now.

That's true, It also looks like it would have room to go west as well, But like we said, Its out there and won't get invested until the weekend at the earliest

Looking further out in time...early March (post 3/3 or so) really looks awesome on the Euro ensembles. Its really hitting building a big western ridge pretty far poleward into the arctic. Probably some response to the tropical situation in the Pacifc....and still a big weakness in the height anomalies in the the southern Davis straight and NE Canada region.

 

No signs of Morch as far they can see.

I wonder if some folks can tickle 100 inches this winter?

 

 

This is certainly one of the patterns you want to see if we want to make a big late season run. Its not going to be easy...I'd prefer to see some slightly colder air around to give us a bit larger margin for error, but what we have is plenty adequate as long as we keep that block pushing systems south of SNE as they exit the east coast.

Could end up being a special season for those folks that are 65-75 inches YTD. A month ago normal seemed good. Now we're encroaching on special if things can work out for us
