This is true . So you’ll need to enjoy and root for dews. I think it’s a Dewy summer and not high heat 

That sounds like New England climo summer to be honest.

As a full region we have definitely gotten more humid over last 10-20 years. Growing up we used to get dry downs that lasted and don’t get those much anymore . It’s especially noticeable at night with warmer mins . BTV is a prime example .

Stop with that woke nonsense. Do you think the EPA would be doing away with clean air regulations if that was true? Follow your president!

Should be AN finally by the 3rd. Doesn’t look crazy though. 

A few upper 80’s  days, retreat back to 70’s then bounce back up again.  
I feel like there’s not going to be any prolonged high heat or prolonged BN this summer. Just up and down steady as she goes kind of summer with bursts of HHH but nothing remarkable.

Yeah I should’ve clarified… not 1950s New England climo, but like today’s/2000s New England climo.

Vegas odds would be on dewy surface moisture levels, not big heat, in the means.

Too much crap and moisture in the atmosphere for the big heat numbers but that also means it’s humid with warm nights.

Lower diurnal range weather.

Won’t be any below normals this summer . You’ll be hoping for days like today by July

Any idea of when we should install?

Why would I want a day like this in July?

40’s? Should be 50’s for lows even some dews later in week or weekend 

47 attm here.  Tonight, Sun, Mon all get into the 40s before we warm here

Wasn't there a good one in May of 1976?

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.

We’ve had many summers last 10 years with dews regularly in 70’s. That’s the new climate as we go humid subtropical 

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!

Precip plot for this past storm clearly shows the mesoscale "thingee" track over sern MA.

Mesolows are notorious for enhancing rainfall.  Broad rotation increases updraft strength and low-level convergence locally.  The mesolow also explains the unusually high LTG density for a Nor'easter, and also the fact given it is late May, climo says there is just more convective instability around in the mean.

What was amazing is the apparently the HRRR caught on to this feature 24 hr before, showing an enhanced swath of R++ S Coast of MA to BOS.

Last time there was this much LTG in a Nor'easter here I think was Oct 2014.  Need to check my archives on that when I get home.  CoastalWx may be able to pinpoint this one!
