One more…LGA -7/-20 and 35kt sustained lol

LGA,1943-02-15 13:00,METAR LGA 151300Z AUTO 29335KT M22/M29 A3010 RMK AO2 SLP196 T12171289 

Central Park hit -8 that morning, 3rd lowest since 1869 there and 6° colder than anything since then.
CON touched -37 on 2/16/43.  It's a good radiating spot, much better (usually) than PWM where an incredible-39 was recorded.  I'd guess that among US towns on salt water, one would need to go north of the Aleutian Peninsula to find a colder morning.  2nd coldest at PWM is -31, at 11:59 PM on the 15th.  3rd place is -26 in Jan 1971.  Both the 15th and 16th were 40/41° BN, with temps -2/-31 and 7/-39.
NYC's longest 32-or-lower run of 16 is the same Jan 19-Feb 3 timeframe as at Boston, but in NY the mildest max of the 16 days was 29.  BOS' max in that run was 31, on Feb 3, but had maxima 28 or colder on the other 15 days.

Modest -3 here this morning, after -23 and -18 the previous days.  However, the 15-25 mph wind probably puts the WCI near those 2 calm mornings.

ORH back then was a coop so it kind of sucks....the hourly airport obs didnt start until 1947 I don't think and it didn't go official until 1948. 

Was that 1943 temp legit?

Yes most likely. It was a ridiculous airmass.

This type of cold hits different when there is snow on the ground. How deep winter should be. But I am soon ready for warmer weather and some stretches of nice spring like weather. That first stretch of 60's we get is going to be something.
