Topped out at 50F.  We take

Love the variance in New England.  Upper 20s this afternoon with snow showers up here (4” past 24 hours) but still at a low elevation... continued flurries.

I can’t wait till that first sunny 50F day.  I love that type of year when it’s mild over snow.

High of 29° here with light snow on and off all day. No real accumulation though but combined with the inch or two from the other night, its made things look much nicer. This warm up reminded me of January thaws before they became all out blow torches. Settled the pack and put a crust on it but didn’t come close to clearing my roof, yard or driveway.

Central VT got a good squall axis of 2-4" with the arctic front.  Up north of that axis we had a half inch here, to 2" at elevation... now this past event added 3-6". 

Western New England in the meso-scale zones have done well with squalls, upslope, and random snowfalls this winter.  With a dearth of widespread synoptic events, we are surviving on the localized stuff.

It was difficult to measure after the squall. I ride through several 3’ drifts tonight. Pretty impressive for the small amount of snow.

Even 01-02 threw us a bone or two at the end of March towards the equinox that season IIRC. 

I remember a couple events close together in Mar 2002...around 2-3" on 3/18 or so and then we had 7" on 3/20

The records for Randolph say I have about 45" of snow left to go. 

Doesn't look very promising to me on the models since we punt half of March at least, but we will see. I could see a sloppy 30" dump at 32 degrees in April after most of my pack has turned to mud that kinda cheats me most of the way there, I guess.

Larry Cosgrove is on board with a return to cold and  potential snow in the 2nd half of March.

Is he on board with :

A   ...  sun being mid September inferno by then ... ?

B   ...  any model run/blend or technique therein deriving pattern expectation, for that range, is historically and will likely be proven again... suspect while the hemisphere is adjusting daily to that forced +d(watt/sq*m) insolation as it increases S-N so quickly to become factor-able perturbation in the guidance.   ...big words for, "the sun f*s up winter-profiled outlooks good and proper nearing the Equinoxes."

I get 'why' he/others/ et al are saying this .. I'm not blind to the models - in a vacuum sure.  Can't do that tho - just bear the above in mind, that's all.

Those models have historically proven susceptible to these factors above.  And, I'm also sensing a present lack in necessary awareness of these above ... People are treating next week's warm up as some ..intermediate thaw and then it's back to the winter hope scheme... 

Nahhh... get real.

These 'para' phrased quotes that get bandied about in here.  He might have said that ..or at least intimated that caution re A and B above - if he's a good Met he is at least thinking about that... 

I have seen countless delicious patterns on March 20th+ when projected from earlier in that month ...  end up tasting sour when they come to pass  because of rather sudden normalization of the gradients by irradiance bathing .. In fact, trying to do risk assessment/determinism in April also suffers this too. It's not every case, either - it's just increasing error tendency.  We've had blizzards in May ... but we also tend to confuse/ .. or remove the sloping probability reality, replacing it with absolute interpretation when reading these skeptical posts.  Don't.. I'm not say it can't ... it's getting harder, fast.

I mean ..duh, 2 week intervals are always 'edubacated'  guess work in the best of times, but spring?   Mm...'spring modulation effect' is on, and is notoriously adding to that uncertainty even more...
