Concerning the "extended" storm snowfalls total in NNE, I was looking at the hydrological reports from GYX through 12z Sunday. Gray Knob in NH (elevation 4375') reported 45.7" for the storm ending around 12z Sunday! This is the cabin there presumably that is run by the Randolph Mtn Club? Day/LEQ/SF: Thu 2.05" 9.0" Fri 2.68" 28.3" Sat .53" 4.9" Sun .40" 3.5" This matches well with the HRRR/3 km NAM 10:1 snowfall total forecast for this area (40-55"). Is CoastalWx impressed?! Nice to have verification of these very high totals that the meso models often show. Now only if we could get something near the summit of Mt Katahdin! Also 63" OTG Sunday AM Gray Knob. Highest late season snow OTG for New England I have seen is 135" at Mt Mansfield the 3rd week of April 1996. 27" fell in three days from a cold upper low to raise the snowcover to this point. If you want to view the hydrological reports from GYX, go here: https://mesonet.agron.iastate.edu/wx/afos/old.phtml and enter "HYDGYX." There are other hut/cabin reports that show up in this bulletin, but Gray Knob was the only one that reported consistently throughout this past storm. You can go back up to 1500 versions of any NWS text product, which mean for the lesser issued bulletins, you can go 10+ years back in some cases. Even the text products under the former WSFO/WSO codes, like BOS/PWM/ORH/PVD/CON/BDL/BDR/ALB/NYC, are here, and go back as far as 1983. A lot missing though for these codes, but there is some cool stuff to be found!

Noted a report on this thread 3-4" of sleet in MA. What location(s)? I ask b/c it is not common for anywhere in New England to get 3" or more of sleet in storm, just based on empirical observations. You see it more often it seems in Dixie/South or continental climate. Two storms ago with the blockbuster snow amounts in NNE, 3" of sleet was report at a couple locations in ME.

BOS the day after the snowstorm with full sun only had a max of 25 F. That was *lower* than the previous record low *min* for the day! -20 to -25 C at 850 behind the storm. Probably one of the coldest 850 on record NEUS. I do recall very strong but quick cold shot in early April 1995 (no real storm, just a strong FROPA). 1000-500 thickness dropped below 500 dm for a short time in NNE!

Wow. What is your snowfall average for the winter? Elevation?

CoastalWx wrote: The only storms that impressed me was the one before Christmas and this one. This one wasn’t a classic nor Easter though. 60kts from the south at 850 will deliver the warmth aloft for sure. It was juiced for sure. --------------------------------------- No, not a classic Nor'easter, rather stringy pressure pattern NNE to SSW. I recall a rule thumb decades ago that said, "N-S orientated 850 lows do not usually produce large areas of +SN." Well, that did not work out here! My point is that winter storms come in a spectrum, and thinking "classic Nor'easter" all the time, you are going to be disappointed. What matters is what the storm prodcues, no? Don't look for the 970 mb KU monster with the perfect WCB and CCB all the time! Take Dec 23, 1997. Nothing special for a pattern or sfc low. 4-8" max forecast, and it ends up 12-24" in SNE! Mega weenie CSI bands or DGZ zones don't need a crazy comma head with a 510 dm 500 mb low moving in! Or how about CoastalWx's all-time "surprise" fav -- March 6-7, 2013? Let's have the sfc low go out 600 mi SE of ACK, and Blue Hill gets a top 5 snowstorm of 30!" Or that one storm in the mega blitz Jan-Feb 2015. We got a burst of snow in SNE in the evening with this mesoscale thingy clearly showing up on radar as a curl. It moves N to srn NH, and stalls. Then the sky becomes partly cloudy over parts of sern MA for a time not long after midnight, then the mesoscale thingy drops back S, the 500 support moves in, and its snow weenie heaven just before sunrise with ++TSSN over ern MA. That was nuts! One of the oddest big snowstorms I have seen. But in the end, still buried! See a theme here?, non-standard, outside the classic box snow events get the job done and can be among the best ev-AH, esp. b/c of the surprise factor! So this most recent storm falls outside the box. Yes, it did not get SNE with big snows, but it was very close. And we are talking late March here. If it was a month earlier?

This much ZR in a Nor'easter? That is quite uncommon. Not your typical overrunning/CAD situation with waves on a E-W front and cold wedges inland way to the SW. Also getting 3" of IP in any storm in New England, that's uncommon as well. You typically see that in the SEUS and Southern Plains. And to have blockbuster snow amounts just NW of this sig ZR/IP area at the same time? Even CoastalWx *has* to be impressed! Yet another over-performing storm in New England this winter, whether it be rainfall, snowfall, high winds, or coastal flooding. We've had it all. And looking at the pattern and GEFS for the next two weeks, all sort of "fun 'n game" potential lined up. This time of year, you are not going to get the long range explicitly showing a sig snowstorm these parts, but you can't deny the pattern is there for perhaps something. Why not? I think we let the furnace meteorological winter get to us too much. I say, get the big snows any way you can, even if it is a "bookend" winter, like 1981-82 and 1996-97 were. CoastalWx saying to himself now, "PLEASE let's get a March 31-April1, 1997 or April 6-7, 1982 repeat! Heck, he will even take May 9-10, 1977 or April 28-29, 1987, even though Weymouth-land missed out these two storms!

Oh, CoastalWx must be pining big time!

Thunder reported at Lempster NH around 8pm from a reliable observer I know. This matches a back end weenie +SN band on radar the moved thru in the last 90 min. This is the 3rd time he has had thundersnow this winter, the other two were the two strong cold front snow squalls days, the most recent on 3/20! Not so bad a winter after all, right CoastalWx?

Scott's all excited that BOS dropped from 42 to 37 F in 26 min!
