Current temp is 11 here.

13 (identical to morning minimum) already before 9 pm. If we get down to 11 before midnight, we'll hit the -20 departure jackpot.

It happened!

 

11 before midnight. 18/11. Stunning -20 departure.

[Morris]

Record low at LGA yesterday (matching) and today right at midnight.

Record low at JFK for both days as well.

Yesterday's low temperature in New York City was 11°. That is the coldest minimum temperature since February 14, 2016 when the temperature plunged to -1°. It is the coldest December temperature since December 20, 2004 when the temperature dropped to 11°.
Monthly Mean Temperature for NYC Through:

12/28 37.0° (0.9° below normal)
12/31 35.0°-35.3° (12/28 estimate: 35.0°-35.6°)

Per sensitivity analysis, the estimated probability of a below normal monthly anomaly: >99.9% (12/28 estimate: 86%).

There remains a possibility that the temperature could fall below 10° before the ball drops on Times Square to ring in the New Year.

Tomorrow's clipper will likely bring a coating to a half-inch of snow across the area. That won't be much, it will add a little to the month's above normal snowfall and it should provide a reminder that winter 2017-18 remains on course for above to much above normal snowfall for the region.

Next 8 days down to average 18degs., or 16degs. BN.

Temp. here is 12.5degs.  Basically the same continuously since 10PM last night.

...11* here in Eastport..Barometric pressures are v. high @30.35mb.

...ice should be thick enough for some pond hockey on Saturday..then add some

light snow falling..you got winter nirvana!!

Yesterday alone added 0.65 degrees to the monthly negative departure. The magic of a -20 day.

Only the 5th time since 1950 that NYC dropped to under 15 degrees during the 7 days following Christmas after rising over 50 the week before. This goes with the big temperature swing theme that we have been experiencing since the end of August.

Man I miss my pond hockey...too old now

I know 16 days is the maximum consecutive days of <32 degrees. for NYC

 

I'm curious as to consecutive days <20 degrees and  days < 20 degrees for maximum highs in a given winter season

Most high temperatures below 20 degrees: 11, 1917-1918

Most consecutive low temperatures below 20 degrees: 20, January 3-22, 1893

Don, do you mean from 1.3.1893 to 1.22.1893 the temps never got above 20 degrees?

I meant consecutive days temps never climbed above 20 degrees.

Sorry for my miscommunication

No, 11 is the max so that only means the low temps. I doubt the record for most consecutive days below 20 is greater than 5-7

Interesting that you don't hear about the rivers freezing up during those years, like you do about 1875 and 1888. I'm guessing the record keeping generally wasn't reliable during the 1800's.

No. 

Most consecutive high temperatures below 20 degrees: 7, January 11-17, 1893.

The same is true for most consecutive days with high temperatures of 20 degrees or below (same dates).

There were some news reports, but it seems that as the 19th century approached an end, less coverage was devoted to weather and weather-related events.

From January 12, 1893:

“New York was an ice-bound city again yesterday [January 12]. Ferries ran at irregular intervals or not at all. Big steamships could not get to sea and vessels were frozen in the ice all over the rivers and bays… The Upper and Lower Bay and the East River became fields of ice through which only the most powerful craft could make a way… A great sheet of moving ice spread between Staten and Manhattan Islands…

Of the fleet of 500 tugs in New York Harbor 250 were said yesterday to be laid up on account of injuries received in the ice blockage of the preceding day. The ice prevented the use of drydocks, and so disabled tugs had to tie up to their piers and wait.”

Source:  “New York Walled in by Ice,” New York Tribune, January 13, 1893

From January 16, 1893:

Newport, RI: “Last night was another cold one, and the result was that the inner harbor is now practically closed to all craft.”

Bridgeport, CT: “The ice blockade in the harbor grows worse each day. No sailing vessels have entered or left here for ten days and the steamers City of Bridgeport and Nutmeg State can reach their piers only with difficulty.”

Philadelphia: “The day was intensely cold here… The effect of the severe weather seems to be felt in every channel of communication, by rail as well as by water. River navigation is almost at a standstill. No boats are moving in the Delaware except the ferryboats, iceboats, and tugs.”

Euro doesn't go above freezing for the entire 240 hours. The vast majority of days not even remotely close. It ends with the city below zero at 240.

If this occurs with only a dusting of snow I’ll be leaving you guys for the loony bin.

as far as the 1893 record I’m more impressed with the number of highs below 20 then the lows. NYC in the 1890s still had sheep grazing in Central Park and farms above 90th street. So it radiated just like the outlying suburbs do now 

[ForestHillWx]

Back down to 8 degrees. No wind; almost enjoyable walking around in it. Something about cold air rushing into the lungs. 

[tomcatct]

Ran out for some gas and mega millions tickets..and you're right, did not feel that bad out there..very calm. .some snow &wind would be nice !!

KFOK 5 and falling fast. Let’s see how low they go before the clouds move in

Don what is the year that holds the most consecutive below 32 degree high record? I heard that the record is 16, but not sure what year it's from.

Do we have a shot at breaking that?

2/8/79: 0

Ed, is that from NYC?

I got the 1940s figure from WABC's Twitter feed, they said the last time NYC had a below zero low in February was in the 1940s.

I was going to ask them about 1961 because I remembered reading there was an extreme arctic shot just before the big Feb 1961 snowstorm, didn't read anything about 1963 or 1979, outside of the fact that 1979 was a very cold winter nationwide and we got a big surprise snowstorm in Feb 1979 that was supposed to miss us to the south.

You think NYC will get past -5 degrees one night in December?

I have doubts about getting lower than -2 in any month.

Although somehow LGA got to -3, so I guess it's possible lol.

-5 has to be considered the limit though, I don't know what it would take to get to -10 unless we were in another ice age.

Interesting how the 1917-18 NYE temp is 10 degrees colder than any other temp recorded at that time in any other year.

Next 8 days still averaging about 18degs., or about 15 to 16 odegs. BN.
