I moved to Silver Spring MD in 2020 for a job after living most of my life in Woburn MA. The avg temp yearly in DCA is 6 F higher than BOS, and the DPs are relentless in the summer, esp along Chesapeake Bay where they get to 80 F often. My first two summers here, I was sweating a lot, but by the third summer, it was not nearly as bad. Point I am making is that the body adapts to warmer (or colder) temps in a relatively short period time w/ no ill effects. But that nothing to to what happens in the Middle East along the Persian Gulf, specifically Qehsm Island, Iran. Dew points every summer get into the 90s, and typically in August it really maxes out. Two years ago, it was 100/97 around sunrise one day and last year the same. The METAR (OIKQ) reports I have checked over time, and the temp/dp are valid based on the wind direction, SSTs, and other factors, such as FG present or not. Population of the island is 150k, and many do not have AC. Yet they do just fine or at least can handle it. So it makes what we experience in the U.S. "easy" by comparison!

Scott needs to pick one!

May 9-10, 1977. Not all elevation either. 9.5" BED and 7" PVD. The 500 mb evolution was extraordinary. Giant 500 5-contour cut-off over the NEUS. Sfc low 990 mb.

That May 1967 event was epic. 10" of snow Monadnock regions. MWN 24.9" for a record May snowfall. Minor accums into central MA w/ the latest on record flakes in the air many locations, at least going back 60 years. Winds gust as high as 90 mph on the coast and ACK had over 7" of rain. May 1967 among the coldest Mays on record for the NE. BOS was -7 F for the month.

At least CoastalWx gets this consolation "prize!" Very impressive event synoptically. I'll post later on it in more details.

So Scott, did it rain so hard in Weymouth like that time when you lived in Dorchester you were concerned about house flooding?

As CoastalWx has already lamented I bet, "why couldn't we get this 3 months ago!!!" Set up synoptically is ideal for a big snowstorm, but can't fight that it is late May. Still, I bet there will be some S+ surprises in ME/NH/VT. Excellent comma head and low track w/ max dynamical cooling aloft as 500 low passes right over the region. S/w swings around the base of the mean trough and does 90 deg negative tilt w/ a W-E elliptical, oval-sharped, closed 500 low -- about as classic as it can get for "backlash."

For May 3rd this is excellent. Not often you have this kind of widespread svr wx in early May in SNE.

Betcha didn't think it would make it to ern MA for svr!

CoastalWx better retract his MEH attitude!

Damage in Hampton NH part deux soon! ARe BOX radar reflectivities running a bit hot? Either that or GYX is running cool.

This is pretty darn good for 5/3. Microburst Hampton NH earlier.

Ignore the fact we just had a great late season snowfall in SNE. Oh, but NIMBY, so who cares? https://www.youtube.com/watch?v=w_6bAt_HwnI

I'm sure CoastalWx will agree wholeheartedly!

Blue snow is a result of the high liquid water content. You typically only see that when you dig into the snow and there is more then a foot on the ground.

Sounds like a good job for CoastalWx! Odd that the HRRR just picked that one area repeatedly. Why didn't it do it for other mtn peaks that were even higher then Brace Mtn in the area? The 3 km NAM does this systematically all the time for all higher peaks, but HRRR singnaling out one mtn for multiple runs? Not sure I have seen that before.

Crazy mountain QPF/snow bulls-eyes are a big 3 km NAM issue, but not nearly as much for the HRRR.

23z HRRR was not a fluke. 00z HRRR even more aggressive. Looks like it is focused on Brace Mountain NY (elevation 2311 ft). It has a 3" QPF bulls-eye there, and wicked downslope screw zone for pcpn just to its W. Kuchera says 28.6". Why not? Low track and flow is right for great upslope flow this area. Of course, we may never get verification unless a true weenie goes up there to measure, but either way, some pretty amazing totals for April seems likely this area. EDIT: Going back several runs of the HRRR, and it is consistent w/ the Brace Mtn bulls-eye.

Not if the band is in the right place and pivots.

23z HRRR Kuchera shows almost 27" right at the intersection of the MA/CT/NY border. CoastalWx has to be impressed! Berkshires/Catskills special? Slide Mountain could do *really* well!

The title of this thread is "Please end it." Well, CoastalWx will still have to wait b/c no sign winter wants to end anything time. If the ECMWF a week from now is any sign, well perhaps a "late season surprise" may still happen!

I recall NWS PWM continued the winter storm warning well after the event was done and when there full sun b/c the melting was causing a huge hazard due to ice falling off everything.

I saw a mention in a NWS chat group that the BOS -SN reported was most likely PL, but I can't confirm if that was indeed the case.
