It seems to go in streaks. Numerous wind and hail reports along the South Shore since May. Other times the convection focuses near the North Shore.

Seeing pictures of .75 inch hail from Farmingdale.

This may be one of the best years for early season hail since late May.

Steep midlevel lapse rates win again. Radar detected hail near Malverne.

These 75 degree dewpoint days usually deliver convection around the area. First cell firing near Valley Stream.

Fairly typical 2010’s June for the temperature departures. We will finish with a very small + departure. These repeating monthly patterns allow for easier seasonal forecasting. The typical 2010’s winter starts out with a warm December. This is followed by a colder start to spring in March. Then a cooler beginning to summer during June. Fall gets off to a slow start with summer heat lingering heat into September and October. November can be the one cool fall month.

I think Europe will finally adopt air conditioning now. https://www.washingtonpost.com/world/2019/06/28/europes-record-heatwave-is-changing-stubborn-minds-about-value-air-conditioning/?utm_term=.ea277d2c3a0d Until now, fewer than 5 percent of all European households have been air-conditioned, compared with 90 percent in the United States. But Europe’s air-conditioner stock is estimated to roughly double within the next two decades, according to the International Energy Agency (IEA), as record heat becomes more frequent and prolonged because of climate change. On a continent that has long shrugged off air conditioning as unnecessary and where doctors still debate its potentially harmful side effects, this week’s quest to find cooler air may foreshadow a drastic change in Europeans’ relationship to the air conditioner. Dirk Trembich, the head of the Berliner Klima air-conditioning company, said interest began to surge in April 2018 — ahead of a record-hot summer. Demand still hasn’t faded.

They needed a clearing away from any trees for a proper weather station sitting. Too bad there wasn’t an open area in the park for NYS Mesonet to set up a new station. Proper sitting NYC incorrect sitting under trees

Not enough sunlight is getting through to the NYC ASOS. Someone should take some new photos. The last batch was posted 6 years ago and it was already in deep shade. http://www.weather2000.com/ASOS/NYC_ASOS.html
