Something I saw recently caught my attention, Central Park's highest low temperature ever was on July 2, 1903 at 87 degrees. The high that day was 91 degrees. There was 0.53" of rain that day. I do not believe hourly data was available back then. It seems almost inconceivable that there could be over a half inch of rain in a day (not necessarily all at once) and not have the low temperature fall below 87 degrees. 

Number of consecutive days without an inch of snow for Central Park:

1) 383 (1998)

2) 381 (1955)

3) 371 (Present)

Number of days KISP have gone below zero:

1963 - 1988: 25

1989 - Present: 0

As a reference, Washington, DC (KDCA) went below five degrees four times in 1994, hasn't done it since.

Nantucket likely broke their all time record low which was -3.  

Block Island is (-6), that is beyond impressive.

Looked up January 1982 statistics for Central Park, seven days with lows in the single digits, six days with highs under 20 degrees, all from January 10th through the 27th. It was a different world back then.

The period from December 28th through February 20th represents 55 days. It is conceivable that Central Park may have daily mean temperatures above normal 52 of those days.

Progression of New York City's record streaks of above normal days:

Something about this chart confuses me, what are the averages relative to? January 1869 had no averages with official recordkeeping beginning.

With the overnight guidance showing a slightly slower arrival of the cooler air tomorrow, the probability that NYC will see its warmest January on record has increased. 

We are definitely going to have a post-midnight high on Tuesday.

Hopefully we can beat 1932, I dont want this to be another one of those months where a fake 31st day keeps us from the record.

 

Keep in mind January of 1932 would have been warmer if not for the last day of the month.

Fourth consecutive January at Central Park without a single digit reading. Last time something like that happened? 1989 - 1993.

Central Park has had 19 consecutive days with above normal mean temperatures, streak may make it to near 30 in a row before it ends.

Snowing gd rn over the bx,expanding right over nyc. The bx has recorded snow accumulation for the year while cpk hasn't had a trace yet

 

Central Park did have a trace today.

Average mean temperature first eleven days of the year:

Central Park: 45.5 degrees

Las Vegas: 48.5 degrees

Chris, how many times have both January and February averaged 40 or above? I think 1989-90 was close and 2001-02 actually did it.

 

Actually neither, just 1998 and barely at that.

Just had some very small hail (maybe graupel).

How are upper 50's/ Low 60's in January not a big deal?

It's the equivalent of temps being 20-30 degrees below normal in early July.

Because they are like home runs in baseball and touchdowns in football, there are so many of them now, they lose its specialness after a while.

Central Park number of DJF days with maximum temperatures of 60 degrees or more:

January 1869 to February 1975: 233

December 1975 to February 2022: 223

By the way, today I learned the first day of official Central Park record keeping there was 9.0" of snow.

Yea the month was pretty much normal or slightly below with temperatures but below normal with snow. The pattern in December was one I remember from many previous years, cold followed by inland runners followed by cold. Frustrating for us but great for the middle of the country.

Cleveland, Detroit, and Chicago are all below normal snowfall. Sometimes Buffalo gets plastered on TV as if it is representative of the rest of the nation.

Last time Central Park had a winter with three consecutive below normal monthly means in a row: 2013 - 2014 and that is with today's normals which keep on going up and up.

A warmup just before or around the New Year seems likely. Its duration and magnitude is far from certain. Some residual Atlantic blocking could persist in combination with a neutral or somewhat positive PNA. That could temper the warmth--warmer than normal at least for a time, but not necessarily record-challenging warmth. A popular argument might entail the MJO's returning to colder phases by mid-January (?) to argue for a return of colder weather, but MJO forecasts are low skill beyond 7-10 days.

Going to be quite hard to ever exceed the warmth of January 1932 in the Park. That month was so warm, it had a higher monthly average than March 1932. In fact January of 1932 was only 5.8 degrees cooler than April 1932.

Wow that was another season of extremes!  You said 9 out of the other 10 were before WWII-- was the 10th one more recent than 1989-90?

 

No, actually during WWII, 1942 - 1943.

UP UP And AWAY.............with my beautiful Thermometer:       Gonna be the hottest start to any year ever with this nonsense.    +17 by Jan. 06???????

Of Note:    From:  10pm Friday  to  1pm Tuesday<<<<<<32 continuously.     From Dec.29 to Jan. 05 and beyond?>>>>>32 continuously.

 

The Ens. is +11 here.     Op is +17.

It will not be the hottest start to any year, as January 2007 has the record for warmest first week ever in the Park. That week featured a 72 degree day on the sixth, something that will not happen this time.

Again let me stress that it seems to me everyone of these wind gust posts I have made, have failed to live up to the billing they had.      I live near the open ocean and should have noted some of these past gusts---but they have failed since the summer I'd say.      So for the record here are the gusts out of the southeast---hence no snow.....................

 

A word of caution: The ECMWF, which is notorious for overdoing wind gusts, is no where near these numbers.

Did 1989-1990 have the largest gap between first and last single digit lows in the modern era (from the 1950s onwards)?  As I recall the low in December was an utterly frigid 4 degrees.  The only colder December reading I can remember was a shocking negative 1 on Christmas morning 1980 (accompanied by a coating of snow!)

 

The answer is yes, this may surprise you, but it is the eleventh longest timespan in the Park's history. Nine of the other ten date back before WWII.

Yes and in 2014 it was almost on March 1st!  When was the last time it got into the single digits in March around here?

The coldest March weather I can remember was what followed the 1993 blizzard.

Weird thing about 1990 was that it was in the 80s just two weeks after that single digit reading and then it snowed at the start of April.

 

March 19, 1967. Safe to say we will never see another later date in our lifetime.

Interesting stats.  Courtesy Dr. Ryan Maue.  I remember December 1989 vividly.  Also remember what followed for the rest of the winter.  Ugh.  December 23, 1989 had heavy snows coastal SC/NC followed by bitter cold.  Was an amazing Arctic discharge.

The one thing I forgot about that winter until looking it up a few years ago was that there was a single digit low reading on February 26, 1990 in the Park. Of all the winters since, there has been only one other winter with a later single digit low in the Park: February 28, 2014.
