85F/DP 76F as we approach 9am.

Low of 75. Let's see how high we can go. My forecast for tomorrow got knocked down a couple degrees to 101 but remains at 103 for today. White MDT fell a degree short of tying the record high for yesterday, it did set a new record max min of 77. We'll have to keep an eye on those max mins in the days ahead, although I think the upcoming days' records are more like 80. Don't get me started on home station dewpoints haha. Here is a map of current dews.....

Currently 87/75 at IAD 8:44am EDT.

.17 last night with a few gusts and thunder. Seemed like we were about to get nailed but didn't amount to much.

Not rising as fast as one might expect for the advertisement - "90 by 9 am" is reasonable index finger method, and we're not going to make that. some 82's around but most sites are just 79 - with only 20 minutes of cooking time, it doesn't seem 90 as average site temperature by 9 am is very realistic. There is another adage that works statistically, though. "10 by 10" ... so we'll see where we are at that time. This could be a situation where that outflow stuff overnight swept through and processed out our launch pad - so we may just need the extra hour of process time to "catch up" to where we would have been if that did not take place. It's hard to run a historic high jump heat dunk day when the night before gets it's legs kicked out. It's going to be mid 90s/ 70billion one way or the other so it's really all just for show beyond that combination of hell, anyway. Hell, tomorrow could end up being the winner in this stretch - that is, if high heights actually do what they are physically supposed to do this time and that's not allow that kind of thing from timing that way.

84/79 already

88/76 HI 99 at my station

Saturday afternoon with frontal sag ..

Currently 81/70 here in MB. But c'mon, man..."stifling?" You Alexandrians are beastly PROS at handling triple-digit heat in summer...

08:30am 84F-79% humidity. DP 77. Yuck! Our low overnight temp is our seasonal high. How many days til Fall?

Beans and franks?

86/76/96 where i am. I think a lot of us will be 90 by 10-1030.

Corona, Ozone Park, Brownsville, and Astoria already at 90°. https://nysmesonet.org/networks/nyc Corona Temp: 90°F 3h Precip: --

Thursday low imby/Columbia 79.9°

Our home has trees 70-80 feet tall within 10 yards on 3 sides - 4th side same tree heights but 30 yards from the house. To make solar feasible we'd need to cut about a 3-year supply of firewood (5 cd/yr) and buy a new roof. No thanks. 2nd straight evening with all the action sliding to our south. Not even a flicker.

My low was 65.2 this morning. High yesterday was 98. A little too cool for the record which was 99 in 1959.

Should be another loud night for some tomorrow night

Wow that's wild.

Now up to 88 here in HPN.

Think of how many years mountainsides and whole villages are washed away during some of these events.

Newark and Teterboro at 88 degrees as of 8am.

93/76 the last 2 days here. Not all that bad.

Northern Ocean County. The breezes that make the water in LI nice and warm make the water here a cold plunge. Been a much more common occurrence over the last couple years.

On my way to work passing thru Frederick. Car reads 89 nearby stations confirm it nasty out.
