Stein has really infected NNE…seems worse the further north you go. 

The old “blocking leads to meh snowfall” reinforcement up north, ha.

CAR temps have been right around 0.0 departures for two months in the means too.

A coating of FR, ZR and an interesting sprinkle of graupel on surfaces. The graupel looks like ice melt sprinkled everywhere. Roads heading to Simsbury were extremely slick

Freezing rain coating every thing. Didn't see take coming in this A winter. Over 10 inches depth last 30 days. February -5.6 to go with Jan -6 December-5 . Snow of 74.2 which is 16 AN for an entire year.

Weren’t we told not to long ago that one below normal month during winter, would be tough to do now?  I think that person went by the name of Forky…?   Where’s that poster been?  Wasn’t November below normal too?

Icy morning, but the Spring birds are singing away... Hit 43⁰ yesterday and the sun did a number on the snow for sure, melt/compaction took at least 4 inches. Only 10-12 inch depth, with a couple inch base underneath it...

To be fair…we have warmer winter normals now and the region was in our own pocket of cold. But yeah, the stars aligned down there this year for a consistently cold and snowy winter, with a couple of historical events.

It’s been cold up here too, but more tame the further north you go. For a lot of NNE it’s been a meh winter.

But it’s nice to see SNE getting a fun one after a relatively crappy stretch the past few years.

Feels like spring this morning.. actually feels good after the relentless cold this winter

 Same thing here.

It really is like Hoth today. Everything is frozen solid

It was two storms ...otherwise, the same plight as y'all up there.

Just two -

I maintain my philosophical approach this winter, that both are true.  We were cold enough, most of the time.. We had snow on ground, most of the time.  

The winter under performed, relative to those environmental verifying circumstances - particularly the cold enough aspect. 

Know one's asking, but I feel pretty strongly that the pattern(s) required to sustain the cold, is the culprit for only two storms...otherwise, suppression reigns.   I would be willing to venture the idea that any cold patterns are intrinsically limiting organized storm success.  Basically ...the two we got punched through the limitations by other means - and I know what those were in each case.    People of this particular social media engagement definitely don't want THIS explanation for why cold patterns are limiting snow.  The background warming world is causing enhanced gradient --> anomalous basal flow velocities in the geostrophic ambiance.   This occurs, whenever patterns attempts to dip the jets.   

It's a limiting factor.  It's not a preclusive factor.  Speed in the flow, out side of S/W spaces, lowers the absolute value of the d(vorticity) in the means.  Lower d(PVA) results. What remains doesn't have enough time before the disturbance has moved off any given region.  

The Jan 25 overrunning on 'roids was a planetary correction event. It was really the only successful MJO wave signature penetrating the Americas I saw since ... a long while actually.  The wholesale lower latitude mass fields surged N with an actual STJ response, and ran headlong into an imposing polar index scenario, on-going.  At those scales, speed's easily overcome. It's there, but the whole thing isn't need jet responses in cyclone machinery/necessity... it's flop over isentropic lift. A very very large on. 

This recent blizzard actually saddle in a temporal window whence the flow relaxed.  I noticed this the week prior to the event, that the GFS was bulging the PNA heights out west E, and the heights over the Gulf o Mex were 4-6 dm lower in that window, the preset velocities 30 to 35kt at mid levels.   That's a receptive environment and when the trough arrived it was able to mechanize a bomb.
