Yeah this is the definition of “fake cold”. Super inverted radiational cooling nights...but if it started precipitating, the temps would be like 44F...lol.

Fake warmth usually happens in spring when the sun angle produces an extreme low level lapse rate. Like those days where it’s a high of 61F but 850 temps are -2C so a bowling ball snowstorm could happen the next day. 

Almost infuriating lol.  Paying for heat right now blasting out of the baseboards because it’s sub-freezing at 30F outside…while a normal mixed lapse rate from the summit down to the valley would yield low-60s for temps from 47F at 4,000ft.

We could have the windows open right now if it was dry adiabatic; would be like a summer evening.  Instead the ponds are growing ice.

It would be worth it if you were preserving a snow pack. But it’s the worst when there’s no tangible benefit to the cold.

Opposite of how global warm has manifested itself on average.

And opposite of recent months.  For July-October my 24-year average diurnal range is 21.66°.  This year it's 17.85° and both July and September set new lows for range.  After yesterday's 56/23 the Nov max is running 1.5° AN while the min is 4.5° BN.

Good data.  The diurnal ranges have been crap the past few months… this whole warm season after May to be honest.  This fall though was real bad, usually good for those 40 degree swings several times in the bookend season.
