78/76 here. Move at all and sweat profusely.

I get to escape the perpetual heat for the rest of the month. Blast off this evening from Philly, where the HI will be 105 today.

Keep that heat dome over central Europe.

Euro and GGEM bumped west with rain Friday and Saturday. Gfs farthest east although 6z is an asshair west of 0z. Gfs is most bullish on rain with storms this evening though.

Could you still post my morning updates? I need someone besides Justin Berk that says is going to rain everyday lol. Enjoy your trip. 

82 with foggy windows. Fingers crossed we get a solid line of storms later on.

WPC has a slight risk of excessive rainfall east of I-95 Friday into Saturday. Wouldn't be surprised to see that expanded westward some. Depends exactly where the front stalls. Guidance continues to indicate some h5 vorticity moving northward in the flow around the west side of the Atlantic ridge, and that could pull the boundary westward a bit. Looks like a possible setup for training convection.

A good delimiter for big-time heat years is whether there are 20 or more 95+ days.  There have only been 12 of those in DCA history (2016 being the latest, 2012 having the record of 29).  We are currently sitting at 10 with plenty more to come.  If you do year-to-date, 2024 only trails:

  • 2012 (14)
  • 2010 (11)
  • 1991 (13)
  • 1911 (11)

Interestingly, in 2016 the heat was backloaded, with only 1 95+ day through 7/9, on the way to 23 total.

6/20 - High: 91, Low: 73

6/22 - High: 100, Low: 77
6/23 - High: 99, Low: 81
6/24 - High: 91, Low: 76
6/25 - High: 94, Low: 69

7/3 - High: 88, Low: 70
7/4 - High: 94, Low: 74
7/5 - High: 98, Low: 77
7/6 - High: 98, Low: 81
7/7 - High: 97, Low: 80
7/8 - High: 98, Low: 80
7/9 - High: 99, Low: 79

That's an average of 93.6 / 74.0, or a daily average of 83.85.

2010 11 and 12 and this year is about to go into those HOF HOT annals 

103 HI here at 11am and 105 at two others.  Someone will hit 115 and it’s worth  restating that is essentially in the shade and at rest.  Exerting in this direct sun likely produces a wet bulb type effect of 120-125 

MN Transplant good at anecdotes and in 1996 I was driving players to DC tennis tournament and there were 6 matches scheduled for 2om start.  It was 100-102 at start time with brilliant skies and full sun.  One match finished, all others one or both players retired.  They changed the start times forever after that .  These are about the fittest guys in the world.  I asked one I think Marcus Zooka and he said only once had he been this hot in Kawala  Lampur(sp) on the equator.

DC can get garish heat and this year is one of those

I grew up in Laredo, TX and this is just your basic summer. Think of a mini Houston with some dry heat days from the Chihuahua desert to give you variety! Also, worked for a company from El Paso (more dry heat). I did business trips there in the summer. Can say that was the only city where you would cross the roadway and slightly sinking into the spongy asphalt (walking).
