Glad to see the SE Mass force field still in full effect for another season.

This weekend also looks horrific, not sure why we are seeing some spin that turd.

That one must be in the sun all day.. it hit 97 the other day if its the same one I looked at.. 92 for a high here today.. pretty impressive for this area.. and yes acs on full blast.. bedroom is a comfy 63 

2 nights ago I forgot to adjust my heating system thermostat.  Our bedroom AC was on high and it cooled our room down that it kicked on the heat.  Heated up parts of our upstairs a lot.   
oops.     Expensive oil being burned.

So what did you measure?

Dongs for the loss but probably near .10 or so. Making up for last summer I guess.

Yeah and if modeling is correct with dry MDW. The following week looks very warm and dry

Complete weather boredom next 2plus weeks. Heat cancel and stein.

51,000 in Boston itself . Where are all the Boston posters with stories and pics of damage?

Surprised by that number.

Was about 3 min torrential and occasional pulses of horizontal windswept white curtains of rain, cars slowed down with hazards on, minor transient street flooding… decent but nothing photo-worthy. Didn’t see any tree damage. 

[Ginx snewx]

From Thursday to Monday not a water weekend. Air temp spots 60 is tops

[Cyclone-68]

Complete meh here. Getting an early disappointed start to severe weather season per usual 

[powderfreak]

MPV is torching again this evening at 79F.

A county north of there, we are 64/63 at the neighbor’s PWS.  

Same temp but drier dew in the field at the ASOS…64/60.

Classic mixed vs calm obs.  As soon as the wind calmed down the temps dropped fast.

[CT Valley Snowman]

Wagons south with the convection tomorrow.

Hope so. AI-GFS complete shutout vs. Euro is wet most of Sat night-Monday

Box had been riding NBM, 50%+ chance showers all weekend...

lmao 

guidance for BDL tomorrow

MAV: 84

MET: 84

NBM: 95 (though showing a 3hr max of 88)

Latest NAM/GFS MOS shows 87-88.  So where do you think the NBM is getting 95 from?  2m temps?  But I checked the HRRR/NAM/GFS/ECMWF, those do not show any higher than 89-90.

Friend in Cambridge had a tree fall on their car. Phil in full effect. The winds were pretty violent in the South End, smaller branches down and such

NH Seacoast Thunderstorm season engaged? 

I may have mentioned this before, but there is something physical about the NH seacoast that make tstms better or intensify here.  Today was no exception, and two waves back-to-back!  Isles of Shoals gusted to 63 mph.

I realized this anecdotally as a kid being at Hampton Beach on vacation each summer, but that can have bias b/c everything is larger than life when you are kid, and any beach view is going to look more impressive overall for storms.

Once the SPC hourly mesoanalysis product came out, I started to watch closely.  What seems to be a factor is that there is at times locally higher 0-1 or 3 km shear/helicity on or just off the NH coast.  Despite the cool ocean temps, a sea breeze here appears to result in intensification of storms in the area.  Not necessarily svr, but a line of showers suddenly becomes active w/ CGs and weak mesos form, as one example.  I've seen too many times for it to be just coincidence.

What may be happening is this - first, once you get to the MA/NH border, any marine stabilization from S of SW winds coming S of LI basically becomes a non-factor.  Second, and most importantly, the low-level winds over Cape Ann are briefly lessened, then pick up again once over the ocean, only to slow again once reaching the ME coast.  So this sets up locally better low-level shear/helicity profile for cells to feed off of.  For years, I have informally called it "The Hampton Effect."

One of most outstanding example was on May 21, 2006.  A nasty bowing squall line was ripping across central/southern New England.  Once the northern part of the line got E of ASH, it gusted out enough that the leading edge cells weakened considerably, so there was nothing but RW-/RW and a bit of thunder.  Once that outflow got to I-95, an isolated supercell developed very quickly and produced tornado at Hampton Falls.  Lasted only about 30 sec, but it was clearly visible as a stout narrow column. See story here:
https://www.timesargus.com/news/weather-service-confirms-tornado-hit-coastal-n-h/article_ed848d36-9e43-5117-aae8-97098039f6ab.html

A waterspout also occurred not far offshore from Rye Beach.

When I saw this and the radar loop, I said, "you've GOT to be kidding me, since when in New England does a tornadic supercell form on a edge of a gust from from a decaying squall line?!"  And SSTs on the NH coast are still pretty cold in mid-May, yet that did not impede things at all.

I think the only other time I was flabbergasted like this was the two mini-supercell tornadoes occurred in the Brunswick ME area on Thanksgiving in 2005.  This was after a couple of inches of snow has just fallen here in the previous several hours!

Ineedsnow says best storm in years 

I will say this event was rather impressive given the slightly anticyclonic flow aloft.  Usually w/ such hot temps and that kind of flow aloft, it remains capped.  One thing though the cell coverage did to rage into a SQLN at first.  Cells were small clusters but intense.

73/68 at midnight in PWM is rare even in peak climo.  Wind just needs to go calm and it'll drop some.
