thanks bucks I missed the 15th had it as 89 instead of 90.  Updated the totals

 

NP - Last time TTN hit 90 was 7/23, needless to say that changes this afternoon as all I needed to do was walk out the door at 5:30, like hitting a wall....

 

PHL is flirting with a record high minimum this morning, have to see if any of the in between hourly ops got below 76

At least at KNYC we exactly matched 1972 for first 90 degree day. I will point out that in those days KNYC had less vegetation and the high that day was 91. So in real world this first 90 day was probably a hotter day than 1972.

Further to this analysis, KNYC has been plagued by a reverse of the UHI effect. New York City's Central Park is actually man-made. Previously it was a mixture of slums, farms and slaughterhouses. It has been progressively getting more densely forested. New York City's weather station is also located there.  Back in the 1970's the thirty-year moving average for summer temperatures included about a week where the mean was 78, implying a high of about 86 and a low of about 70. It could have been an 85/70 split since the practice is to round upwards. By the early 2000's the "78 degree" bulge was cut to two days and in the most recent thirty-year period eliminated. Now the average maximum high-low is rated as 84/69, for the period, roughly, July 10 through August 10. This works out to a 76.5 mean, or a full degree lower than the mean for most of the corresponding period historically.

The number of 90+ days has also dropped at Central Park (KNYC), so that in the recent summer we have only touched 90 for 7 or 8 days (today may be the 8th day).  This summer was considered a cool one.  Summers with similar weather patterns, i.e. relatively cool ones, such as 1969, 1972 and 1979 had more 90+ days.  1969 did have a few 96 or 97 days that clearly would have topped 90 even now but nowadays the same situations that created 90-92 degree Central Park readings now create 87-89 degree readings. All you have to do is look at statistics for LaGuardia Airport (KLGA) to see the difference.

 

I am thinking about originating this as a separate thread.

Here's my guesses for the summer:

 

First 90F

 

NYC: 5/27

EWR: 5/26

 

Seasonal Totals:

 

NYC: 13

EWR: 19

LGA: 14

NBW: 19

TTN: 16

PHL: 22

 

IMBY: 13

 

Going for another low impact 90F year.

 

Last year I had 11 days IMBY. My guess is I'll end up fairly similar or slightly more, but still below the average which is 16-18 or so.

2015 90s season total prediction

 

NYC: 19

EWR : 31

LGA: 25

PHL: 36

 

 

Locking above in for a real # but believe the ranges to be as below.  So thinkin on the hotter end of the ranges. 

 

NYC: 16 - 19

EWR: 29 - 31

LGA: 23 - 25

PHL:  33 - 36
