I dont trust those things, they overreport and are not built to NWS standards

That said we are in the mid 90s here already

Euro now brings the 90s back early to mid next week. Looks like a break for a few days and then we go back to the heat. 

It's 94 with a dewpoint of 67 here right now. Doesn't feel terrible today. 

it reminds me of 1993 and 1999 and 2002 and of course 2010

2024 wasn't that hot, let's please not use average temperatures.

I do agree this is the hottest summer since 2010

Don's pre-summer outlook of a statistically significantly warmer than normal summer looks like it will come to pass with June-July at KEWR top 6.  Very good statistical call barring a chilly August.

Waiting on a thread til tomorrow morning for two 100F days at KEWR,  (for me unexpected in lae June),  to be followed by a potential widespread 1-4" forum rainfall with iso 8"... EPS through 12z/28 cycle continues strong on this, though edging northward.  I also have to think there has to be a stripe of svr near the boundary Thursday?   Just too early for me to be sure the EPS is going to be mostly correct.  From what I can tell, WPC is so far,  accepting the EPS solution. 

Let's see if we can challenge EWR record of 9 100+ degree days in 1993 and 8 100+ degree days in 1949 and JFK 3 100+ degree days in 1966 and 2010, Walt.

EWR moves into tie with '73 / 2018 for number of 95F or higher days season leaders.  Tomorrow ties the hot 1966, 1983 seasons and Wed  1999, 91 and 2016.   Long ways to go for 88, 44, 93, 2010, 2021  and 2022.

A thunderstorm at Janesville, WI, produced wind gusts to 104 mph which flipped over two airplanes, and blew another plane 300 feet down the runway. The northeastern U.S. experienced some relief from the heat. Nine cities reported record low temperatures for the date, including Saint Johnsbury, VT, with a reading of 42 degrees. Barnet, VT, reported a morning low of 33 degrees, with frost reported on vegetation. (Storm Data) (The National Weather Summary)

Based on my experiences in 1993 and 1995, we need to pass two benchmarks to hit 100 degrees here.

90 degrees by 10 AM

and

95 degrees by 12 NOON

Is this a total of June and July... I thought your other chart was better the one that showed the temperatures starting with the summer solstice (because that's around the time our heat began, the first half of June was cool and rainy)
