DCA, along with likely logging another 97+ day, has been hanging around 107-110 for the heat index most of the day.
Here, our dewpoint has been around 80F all day - it's literally arresting when you step outside.
Lol there is a video of Trudeau going for a run on the Mall at around 7am this morning (DCA was 84/75 at that moment) - hope my dude brought some water.
I believe it - DCA maxed out at 110 I believe (at least on the hourly ob). Here we were between 110 and 115 most of the afternoon.
Right now Quantico is 88/80 with a HI of 104. Nasty stuff.
