The Mt Pocono stat surprises me.  You'd think in all these heatwaves in 93/95/99/11 they'd have gotten over 92 at some point

I'm shocked they haven't been 90 or higher in 12 years.....

[SACRUS]

Clouds blowing right (east) to left (west) around the building ridge.  Yesterday's clouds really limited this from being a 4 day upper 90s - low 100s for places.

Today was the appetizer for what could be a day of historic June heat tomorrow.

Extreme heat is likely tomorrow and possibly Wednesday Temperatures will likely top out in the upper 90s in much of the New York City area and lower to middle 100s in the hot spots in New Jersey tomorrow. Numerous locations could challenge or set new June monthly temperature records.

June Monthly Records:

Bridgeport: 97°, June 9, 2008
Islip: 96°, June 24, 1966 and June 19, 1994
New York City-Central Park: 101°, June 29, 1934 and June 27, 1966
New York City-JFK Airport: 99°, June 29, 1949, June 26, 1952, June 30, 1964
New York City-LaGuardia Airport: 101°, June 26, 1952 and June 13, 2017
Newark: 103°, June 27, 1952

June 26, 1952 is currently the hottest June day on record in and around the New York City area. Out of the five stations from the above list that were operating in 1952, three reached or exceeded 100° on June 26, 1952 (Central Park: 100°, LaGuardia Airport: 101°, and Newark: 102°). All five reached 95° or above. Two stations also saw 80° or above lows: Central Park: 81° and LaGuardia Airport: 84°. Both the number of 100° highs and 80° lows is the highest on record for June for this five-station area. 

For June 26, 1952, the five-station average high was 99.4°, the average low was 78.2°, and the mean was 88.4°. The average high and mean are the highest on record for June. The average low is the second highest on record for June. June 21, 2012 was the second hottest day, overall, in this region. Its average high was 96.8°. Its average low was 78.4°. Its mean was 87.6°. That average low was the highest on record for June. The average high and mean were the second highest for June.

The ENSO Region 1+2 anomaly was +1.0°C and the Region 3.4 anomaly was 0.2°C for the week centered around June 18. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.47°C and the ENSO Region 3.4 anomaly has averaged -0.03°C. Neutral ENSO conditions will likely continue through at least late summer.

The SOI was +13.85 yesterday. 

The preliminary Arctic Oscillation (AO) was +1.425 today. 

Based on sensitivity analysis applied to the latest guidance, there is an implied 80% probability that New York City will have a warmer than normal June (1991-2020 normal). June will likely finish with a mean temperature near 73.2° (1.2° above normal).

Don did either Allentown or Philly hit 100 today? I see Allentown is at 97 and Philly is at 99 right now.

 

[Roger Smith]

Early climate report for NYC indicates

96 max ties daily record set in 1888 _ second highest value on 23rd was 94F in 1966. 

80 min sets new record for date (77 1888) and is only second 80+ min in June (81 June 26, 1952). 

There have been a number of 79F mins including non-record June 26, 2003, and daily records for 10th 1984, 21st 2012; 24th 1909; and 30th, 1945, 1959.

[dmillz25]

97 for the high here. 100 is almost a given tomorrow 

[Santa Claus]

IMO sun angle is important

you keep temp and dew at the same numbers and this heat feels different at 12 and 5 pm

I see 99 at PHL but not sure if the intra hour readings got there, you would assume they did.

[SACRUS]

Guessing the mins/lows overnight for the launch pad tomorrow seems like this

 

EWR: 82
NYC: 80
LGA: 81

93.9 & 93.5 for the high at my stations.

Currently looking like mid 70s on Friday, clouds onshore flow

No. We’ll see if Philadelphia can still get there today.

Don, can you see the intra hours between 1400 - 1700?

Recent posting by WFO-PHI confirms that 99 was the high at PHL.

They were 98,99, 99 , 98 the last 4 hours, that is some constancy, amazing they didnt spike one degree in those four hours.

It seems to have lingered from the winter and spring with the record westerly winds that caused all the upwelling. But the current cool spot is much smaller than it was. Though the local SSTs are still a bit below average for this time of year.

you never would have made it through that 1944 or 1953 super heatwave or even the 1993 one lol

Mount Pocono at 93 is crazy, how close is that to their all time high?
