This region really has some cooler force field over it. The rest of the country will turn ridiculously warm and stay that way. 

SW US has Phoenix pushing 105+ and Vegas 100+ next week. GFS OP shows a ridiculous warm/cool gradient LR

It's explainable...

... the prevailing flow is W --> E in the Northern Hemisphere mid latitudes.  As it encounters the N -- S oriented topographical interference of the western N/A continental cordillera, the flow is forced to rise over the terrain.  As it does so, the Coriolis force then deflects toward the N... This is a somewhat exaggerated annotation to cartoon demo that action

In the absence of any wave disturbances moving through the flow, this standing wave pattern above is always in place.  Now ... there are times when the waves in the flow overwhelm this perpetual forcing. There are times when the opposite occurs ... and the above forcing is in sync.  When it is out of sync, the former circumstance, we refer to that as negative interference, thus positive interference when the opposite is true. 

The problem, when there is a trough in the E that means the basal forcing above is constantly supporting its existence.    Not the other way around.   So if we follow this to it's logical end... that means that cooler tendencies should be favored in the east because the flow wants to trough anyway.  Per course, warm west, cool east. 

It's really rather remarkable that we ever get hot here considering this above is a planetary construct really. 

Anyway, so when you sense that it is harder to get it warm and stay warm at certain times of the year, it's probably just because this return tendency above is claiming a few extra weeks per year and favoring it to end up cooler comparatively to the west.  This is at all scales too...  Backdoor cold fronts are also a microcosm of this same effect, really. The flow E of the Berks-Whites ... tries to tuck at all time, as the flow bumps over those elevations and then is forced to descend.  This way we suffer them.  So we have the continental favoring, and an extra factor local to New England's geographical circumstances ...

Also…the 76° at BDL is the 3rd warmest temp on record for this early in the season. 

74 or 75 at every home site on Wunder within 5 miles of mi casa fwiw

That's with snow on the ground.  This is also the greatest temperature and still snow pack combination I've ever seen at this elevation.

Can’t beat a record low all winter, but we get warm for 2 days and blow some away. lol

I wonder if @Typhoon Tiphas any theories as to why we seem to be seeing record maxes fall at a much faster clip than record mins over the past 20-30 years or so...almost as if there were a longer term warming going on of some sort...interesting-

haha... f you

no but seriously I did read a paper recently ( Phys.org ) where CC- attribution is causing:

bigger temp swings.

more frequent severe cold snaps, where the bottoms of the cold are slowly elevating.  They pointed out this latter aspect, too - which I found interesting.

heat waves are becoming more frequent in the summers, lasting on average a day longer, and maxing out higher. 

As far as the lows versus high, I'm not sure of any science discipline to back this up so don't shoot me but I thought low temperatures over eastern N/A were where the ballast of our elevating means were coming from?  check that -

No, all of this is correct. Just messing....spot on.

Wait a sec

... didn't we have 12 to 18" of pan-dimensional snow pack on 12/22/2020, and then zero by the next morning ?  

That was faster than this.   This has taken 3 days and I still have snow 3 or 4" deep

Granted, with 75 air wafting over  :arrowhead:
