The current 500 mb pattern with a trough near the Great Lakes hasn’t typically produced 100° heat in our area. The 500 mb composite for our last 10 July 100° days since 2010 is much different. A deep  trough in the West with a strong ridge over the Northeast has been the norm. So this may explain why  we are getting more onshore flow this time. Many heatwaves in the past with multiple 100° days featured deep westerly flow down to the LI South Shore. The record heat in the Southern Plains is getting drawn NE by a low in the Great Lakes this time.
 

Current pattern has the strongest 500 mb anomalies to our south

Fake seabreeze moved in and just pumped up the dewpoint back to 70

It’s essentially meaningless today and if anything just makes it worse. Long Beach is still around 90 and S Nassau and even into Suffolk are still well into the 90s. I can kinda tell from here that it’s almost IMBY because there are more cumulus building behind the seabreeze front and almost clear north of it. Shows up pretty well on radar too.

This has to be one of our warmest southerly flow days here on the South Shore. Currently 90° in Wantagh south of Merrick Road with a southerly wind gusting to 18 mph. This is what happens when the SSTs at the buoy south of Long Beach get close to 80°.

92/70 currently, yesterday’s 86 screwed up the chance for a 6 day heatwave here. The criteria should be lower for place on the shore…

Or it should have a dew point component. When it’s 89 and a DP of 75, it’s hot. End of story.
