Any idea what the temperatures were like with that.  Was that one of those frigid early 80's outbreaks.  I have a feeling it must have been major cold as in the vodka gels.

Not extremely cold, most of the cold was to the north in Canada as the pattern was zonal.  The low was 19.

Bad trends tonight.  Models track the clipper way north of us. Pna ridge isn't sharp.

Fire up the January thread maybe that will change things around.

The pattern leading up to the record high was one of the coldest we have seen. It was the last time that NYC averaged under 30° from 12-01 to 2-13. So these record highs in the past have usually come near the peak or end of very cold patterns. This time North America had one of its warmest falls without time to build any record breaking cold around our area. I guess this one was more like December 1949 when NYC got the monthly record high pressure for December. That was a very mild December by those standards. February 1934 had a 1050 mb high to our north with historic cold. January 1994 also had a 1050 mb high to our north and was one of our coldest January patterns since the 1980s.

Well this is a shocking development. Looks like 12 will do it for the low here, a bit warmer than forecast. 

[gravitylover]

Looks like 13° for the low. 

[Snowlover11]

16F for a low.

[bluewave]

Back and forth pattern until further notice. Day 1-5 warm up followed by 6-10 cool down. Then a 11-15 warm up.

Would add the caveat that this really applies for the area north of I-78. Central and especially southern NJ have seen less, and drought severity is higher there anyway, so need to see more to start to claw out. Yeah, largely outside "NYC metro", but know we have plenty of posters south of I-78. 

Thanks Matt,  never really sure where all the NY Subforum posters are located... I tend to start at I78 north.. but understand south of I78 as you pointed out in the stats.  I am concerned the drought monitor is not nearly responsive enough (flashy trends both ways).

Not surprising given how dominant the Pacific Jet is with the very fast zonal flow. Most of the storm tracks in this regime are cutters or huggers. In the old days we used to get more clippers diving south of NYC. These days we hardly ever see this track.

Good radiational cooling last night with heavy frost. Temperature dropping into the teens here.

[North and West]

I think people are a bit jaded with how bad the last few years have been....

People also like to complain or be proven right. This is like being in a dysfunctional office setting.

If you have an old school analog barometer, it's pretty much pegged this morning if set accurately. 
I'm at 30.92" after an overnight low of 10F.  Most of the upstate NY is at 31"+ on the barometer, which is 1050 mb+
There are a bunch of single digit lows in western NJ.

[North and West]

hope it does not verify on the 23 i have a doctors appointment that day if i have to reschedule it will be months before i can get another appointment.

Stay well!

12 for a low 

[donsutherland1]

In the past few days, two runs of the operational GFS showed a significant snowfall for the Washington, DC-New York City area. Maps were posted on Social Media. However, the forecast pattern makes such large-scale significant snowfall unlikely.

[SACRUS]

 

26 / 11 off a low of 16 (coldest since Feb 18th/19) and a clear night for the star and drone gazers.  Colder than normal one more day - stuck in near 40 / mid-upper 30s.  Warmer / wetter Sun - Tue AM  0.25 - 0.50.  Much warmer Tue  near / low 60s.  Additional rainfall Wed with near to above normal through Friday.  Colder Sat and through about Christmas.   Should see a rebound to warmer ahead of quick colder period to balance our overall near to slightly above normal to close the month.

1924 - The temperature at Helena, MT, plunged 79 degrees in 24 hours, and 88 degrees in 34 hours. The mercury plummeted from 63 above to 25 below zero. At Fairfield MT the temperature plunged 84 degrees in just 12 hours, from 63 at Noon to 21 below zero at midnight. (David Ludlum)

 

1952: Trace of snow or sleet at or near Pensacola, Crestview, DeFuniak Springs, Quincy, Carrabelle, Tallahassee, St. Marks, Monticello, Madison, Mayo, Live Oak, Lake City, Glen St. Mary, and Hilliard in Florida. Frozen precipitation occurred before noon at most points, but happened in the afternoon at Mayo and Lake City and near Hilliard. Temperatures were above freezing and snow or sleet melted as it fell.

1987 - A powerful storm spread heavy snow from the Southern High Plains to the Middle Mississippi Valley, and produced severe thunderstorms in the Lower Mississippi Valley. During the evening a tornado hit West Memphis TN killing six persons and injuring two hundred others. The tornado left 1500 persons homeless, and left all of the residents of Crittendon County without electricity. Kansas City MO was blanketed with 10.8 inches of snow, a 24 hour record for December, and snowfall totals in the Oklahoma panhandle ranged up to 14 inches. Strong winds, gusting to 63 mph at Austin TX, ushered arctic cold into the Great Plains, and caused considerable blowing and drifting of snow. (Storm Data) (The National Weather Summary)

1988 - Blowing snow was reported in western Kansas, as snow and gusty winds plagued the Central Rockies and Central High Plains. Colorado Springs CO reported thirteen inches of snow. Low pressure in Wisconsin brought heavy snow to the Lake Superior snowbelt area, with 22 inches reported at Marquette MI. (Storm Data) (The National Weather Summary)

1989 - High winds and heavy snow prevailed from Montana to Colorado. Snowfall totals in Wyoming ranged up to 20 inches at Burgess Junction, leaving up to 48 inches on the ground in the northeast sections of the state. Wind gusts in Colorado reached 87 mph south of the town of Rollinsville. Strong northwesterly winds continued to produce heavy snow squalls in the Great Lakes Region. Totals in northeastern Lower Michigan ranged up to 29 inches at Hubbard Lake, with 28 inches reported at Posen. Two day totals in northeastern Wisconsin ranged up to thirty inches. (Storm Data) (The National Weather Summary)

 

1997:Central Mississippi and western Alabama saw significant snowfall of 4 to 8 inches on this day. In Mississippi, this was one of the heavier snowfalls to occur since 1929. The weight of the snow caused limbs of trees to break, which knocked down power lines.

2006 - The Hanukkah Eve Wind Storm of 2006 caused storm to hurricane-force wind gusts and heavy rainfall hit the Pacific Northwest and southern British Columbia. Damage estimates in Washington and Oregon totaled $220 million. Over 1.8 million residences and businesses without power. 18 people were killed, most of whom died of carbon monoxide poisoning in the days following the storm because of improper use of barbecue cookers and generators indoors.

2010 - A rare tornado struck the small town of Aumsville, Oregon, tearing roofs off buildings, hurling objects into vehicles and homes and uprooting trees. No one was injured but the destruction left behind was severe. The National Weather Service classified the tornado as an EF2 with wind speeds of 110-120 mph and they said the tornado's damage trail was five miles long and 150 yards wide. 50 houses in Aumsville and the surrounding county area were affected, with 10 of them being unsuitable for occupancy.
