PhineasC Posted March 4, 2021 Share Posted March 4, 2021 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. 1 Link to comment Share on other sites More sharing options...

Yeah the historical snow climo shows this too...there tends to be a pretty sharp dropoff in snow climo though once into the final week of March but that 3/14-3/22 period or so is not too difficult. Then there is another pretty sharp dropoff in snow climo after about 4/12-4/13 in the historical record. Link to comment Share on other sites More sharing options...

Typhoon Tip Posted March 4, 2021 Share Posted March 4, 2021 I dunno... What I am seeing overnight is the same shit I've seen for a week now.. . The telecon layout is warmer by numerical approach, than the operational individual and blends have tended to appeal like - Not sure which will win... I suspect the operational runs ( should anyway...) might have a special insight being the souped up front man for each family ... but that's not always true. I could see the operational runs suddenly getting more robust with raising heights south of 55 N ...given to that ginormous Swiss Alps rise in the AO curve out there mid month, while the NAO is also bouncing around between neutral to low grade positive - that offers a big gap not being used in the operational runs. You can actually see that in the SE ridge handling for the warm up next week, too... The models have this "NINO" like River coming into California with a huge planetary flux of subtropical jet mechanics riding over the SW U.S.... and the heights over the TV fan open...They don't really represent a deeper latent heat fluxed height response as much as they could - Not sure where that is going ...but the models are not really building heights that fit that mode down stream very well. That's the 00z run... the 12z yesterday seemed to fit both the west coast flow, and these polar indices above, better. So..I'm on the fence... I also think the GFS in general as a separate concern with that p.o.s. N/stream beady-eyed neurotic physics will keep it winter until the end of time if given least excuse imagined, too Link to comment Share on other sites More sharing options...

True .... but what I am saying is not in the absolute sense, either. Not saying it can't - It's a brief op ed against the presumptive attitude, a presumption that is removing the modulation curve in order to get on the far side of next week's warm up as phew, back to our drug LOL... By then, ... " 2nd half of March.." ? heh... Look, if the AO was not soaring to crucifixion heights out there, and the NAO was not in tandem also bouncing around ( albeit shallowly ...) in lower positive range, while the PNA is also tending too flop negative after this vortex interlude we suffer over the next 4 days ...I wouldn't be raising caution flags ... Oh, I might snark that the sun is a cooker. But these are bona fide clad, institutionalized methods for deterministic assessment - they are not cold and snowy. So ...yeah, it's a little odd - .. where is Larry seeing that anyway come to think about it - If I saw that layout of mass field mode/modal indicators at any time of the cold season, I would not be emphatic about any run that looks cold biased relative to that signal.

SnoSki14 Posted March 4, 2021 Share Posted March 4, 2021 I don't really buy the return to winter after mid-month either. Looks seasonal to me to somewhat BN at best, which could be enough for a wintry event...it is still March after all. 2018 ain't walking through that door though.

Then there is another pretty sharp dropoff in snow climo after about 4/12-4/13 in the historical record. Have had 11 snowfalls of 8-19" after 3/15 in 22 winters here, 4 of them in April with the latest being 11.2" on 4/12-13/07. Nothing reaching 6" after that, though it was different when we lived in Gardiner, with 6"+ storms after 4/15 in both 87 and 88. Didn't get the huge ORH dump in 87, however. (Encountered double-digit snows during visits to NW NJ in both 83 [11" on 4/19] and 86 [13" on 4/23] - we didn't think the state would ever again let us visit in late April.)

CoastalWx Posted March 4, 2021 Author Share Posted March 4, 2021 I will say the EPS has shown steady interest (at least how I see it) in that period after the late week torch next week. I don't see the classic look yet, but you have a little meridional flow out of NW Canada, a little Greenland ridging, a little confluence in SE Canada.
