The problem is zero blocking and a progressive high to the north. Initially it is cold enough to snow with the track but the high is retreating northeast in the fast flow. The polar vortex is tight and consolidated there is no northern phasing.

 

 

Ukie has a decent setup...but its the crazy uncle. Still just over a week to go. There will be MANY more changes.

The CMC has the low 50 miles off the delmarva and it's still mostly rain SE PA.

Antecedent airmass sucks. Not enough cold reestablished in SE Canada yet and zero snowpack most of the Northeast even into SE Canada....and that matters. We should hope for a full phased properly timed dynamic system that can create 850 cold on the NW flank with a proper track. Basically a thread the needle....and we know how that goes. But with a week+ to go, maybe we can morph this into a legit winter storm threat. Maybe.

It's a bad pattern outside of scoring on some fluky little events like Sunday could be. Need a SSW or the goose is cooked going forward late month.

 

 

SSWE looks to happen late Jan or early Feb. CfS has plenty of cold next month in Canada and a decent pattern for March....so we will probably get more chances at times both of those months.....of course windows sandwiched in-between warmth.

Last January a decent SSW event the first week perturbed the vortex and Allentown had a top 20 cold month at -5F. 

Problem was we had a drought pattern and anemic southern jet this area finished with 8.9" from half a dozen nickel and dime systems. This year the polar opposite problem :facepalm:

I mean, we couldn't ask for a much better 850 low pass for our areas than what the gefs mean is showing. It's all textbook tbh:

The problem is that there's just not enough cold air in place nor is there a source to tap into as you said above. Outside of a thread the needle situation or full phase/manufactured cold, this one is going to struggle to snow in SE PA unless we see some big changes to the airmass in the coming days.

12z euro for the 14th system is uglyyyyy. night and day from the GFS/CMC. Looks like it's going to be a straight cutter west of chicago. Probably going to lead the charge again like it did for the Christmas system sadly. Still wants nothing to do with the sunday/monday light event too. True Dr.No style.

Could get a severe outbreak on the ECM though so we have that

Euro could whiten the ground with hail

 

Would take either of these or a slot car ice storm. Chasing snow is a nightmare unless you go to W Philly...

43F/Breezy/sun breaking through....and now it's cloudy again.
