June 2026

I think there is a chance of that, especially northern NJ.  There's currently a huge blob of heavy rain and storms heading southeast out of Canada.  It'll be interesting to track what if anything holds together or redevelops.

That’s a fully developed MCS with a nice trailing cold pool. Could survive the trek, we’ll see

June 2026 finished with a mean temperature of 73.4° in New York City. That was 1.4° above normal (2.0° above the 1981-2010 baseline).

July will start with a severe heatwave. The heat could rival that of early July 1966. Much of the region will likely experience its highest temperatures so far this summer with maximum temperatures peaking in the 100°-105° range. Some locally hotter temperatures are possible. Most of the Mid-Atlantic and southern New England areas will see temperatures reach 100° or above during the height of the heatwave. Boston, Burlington, Philadelphia and Washington, DC could challenge their all-time records.

The ENSO Region 1+2 anomaly was +3.1°C and the Region 3.4 anomaly was +1.8°C for the week centered around June 24. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +2.60°C and the ENSO Region 3.4 anomaly has averaged +1.37°C. The ongoing El Niño will continue to strengthen through the summer.

The SOI was -10.83 today. 

The preliminary Arctic Oscillation (AO) was +1.196 today.

Additional Notes:

1) Central Park's highest temperature was likely 97° on June 11-12 based on a statistical regression equation to compensate for tree overgrowth. 

2) JFK Airport had an average high of 81.7° compared to Central Park's 81.4°. This is the largest margin by which JFK Airport's average June high was greater than Central Park's. The previous record and only such occurrence was in 2015 when JFK Airport's average high temperature was 0.03° higher than Central Park's mean high.

Hey all...

Newbie here. I live in the Northwest part of Philadelphia (Mt. Airy is the section of the city), am a Philly Public School teacher (Psychology and history) for 29 years, and have been a "lurker" on here for quite some time. I have learned a lot by reading the Philadelphia, NYC metro, and New England discussion forums over the years. I have been interested in the weather since I was a kid growing up in Wisconsin... I think the summer of 1977 with its heat and severe weather along with the winter of 1978-1979 (I was in 4th grade... we had so many snow days we had to make one up on a SATURDAY) are what sparked this interest. In any event, I look forward to perhaps joining in on some future discussions. Take care and stay cool this week.

A friend of mine who works for PJM said Thursday is definitely going to break a record and that the western part of our region (Ohio, Michigan, metro-Chicago) are likely to place constraints on the rest of our region; but they are working to hopefully minimize whatever those constraints are.

That's definitely concerning

Like.. Restraints on power usage?
