GFS coming in a bit colder for 1/25 too. Nice SWFE look.

Getting deep snowpack is great for reinforcing good patterns. It’s not going to cause an awful pattern to shift but in otherwise marginal setups it can make them better….it basically helps refrigerates the lower atmosphere if you have wide scale snow pack in a region. We’ve had a huge dearth of pack this winter close by so that also makes mild patterns even warmer.

PV being near us in Canada…and yes, we should get an arctic intrusion or two I would think with it lurking so close by.
-
Yep. It looks like an excellent next 5 days up there. If both of those systems pan out like expected, an impressive turnaround would be underway for some spots there in CNE when you combine with Thursday/yesterdays storm.

Yeah 1/25 is all about the WCB stuff. CCB/deformation on that will be way up in Ontario/Quebec

Pretty huge week for CNE/NNE. At least it’s snowing again nearby even if we miss. Hopefully laying some goood pack down will help out a little bit after that. Still think 1/25 might be decent…esp over interior SNE. But I’d like to see even just a minor shift east to get better dynamics in here on the front end.

Weenie run of the 06z GFS. That’s how to run a gradient pattern.

Missing a lot of data though on that dataset. 1978-2001 shows up as missing.

It’s cold enough out ahead of that storm…even if not ideal. The biggest problem I see is the high is literally in the worst possible spot. We just get flooded during the WAA phase of the storm. Once winds finally back to northeast, we’re too mild for snow except over far interior zones where it remains just cold enough. Normally a 534 thickness -3C 850 antecedent airmass would work if we had any type of mechanism whatsoever to hold that in, but when the high is sliding southeast of ACK and out into the Atlantic, we’re cooked. The funny part is both the 18z NAM and HFS did try and flip us back to heavy snow at the end…not really buying that depiction but still entertaining.
