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.

Deep deep winter out there. Let’s get some big numbers tonight. 
 

16.4/1 at WXW1

3.2/-3 at WXW2

[CoastalWx]

High of 15 here. 

[powderfreak]

We’ve clawed our way to 0F here at the base of the ski area.

MVL ASOS has been bouncing around 1-4F all afternoon, with 4F being the high.

[Damage In Tolland]

Got to 10 for a few minutes

Is that 128F by NYC?  lol.  I’m assuming it’s two sites next to each other.

Central Park on the left and LGA the right.

I have a feeling the pits drop really low tonight.

If that verifies then that’s not too bad; I was -9F here yesterday so as cold as it is now

Agree, Yesterday morning was the coldest it's been. -10F

Plus, I won't have to be out in it heading for work.

Same here.  It does not end. We get a few days here and there of 32 plus.  Mid Feb a short break but it looks like another cold shot coming right in after that.

It was a pretty shallow cold shot. That kept max temps down because of lower mixing heights but the airmass itself isn’t exactly earth shattering.

Has there been much mention in this thread of the Feb 1934 cold records? Today's record low max at NYC is 16F set in 1934. December 1933 had been very cold but January 1934 up until this event had been near average. Then February produced record cold averages and extremes. The strongest of these arrived on Feb 8th with a 1050 mb high over Ontario. By morning of the 9th it was -15F near the coast and -30 to -50 F further inland. I believe both Saranac Lake NY and Bancroft Ontario (150 miles west of Ottawa) had lows near -52F. Lake Ontario froze over completely that winter. Toronto had an interval of 36 hours below zero F and a low of -21F on Feb 9th, NYC was -15F. So I wondered what data there might be for New England. A second record cold spell arrived in late February but it was not that extreme, about like today's values.

33-34 was definitely cold here. 12/29 CON had their coldest max on record with -11. The afternoon high here was -15. CON did another below 0 high in Feb with -2. There were record low mins here too, but nothing that really stands out.

Still a stiff breeze.  Hopefully it dies down soon.  

[ORH_wxman]

ORH daily record low max was 10F in 1934 for this date. We have to wait and see if they tied it or not. Their hourly max was 10F but they may have spiked between obs. 
 

They already set a record low max on 1/25…it was vulnerable so 10F high on 1/25 was able to do it. Usually you need low to mid single digits for a lot of the days in January. 

[WxWatcher007]

High of 3.2° up at WXW2. Down to -1

High of 16.5° here at WXW1. Down to 11.7
