DCA also went big that second week of July 1936. 104 and 105 on the 9th and 10th. That said the rest of the summer is unimpressive, including an amazing 60 degree high (!) on June 24th and 70s for highs multiple times at the end of July and early August. It really was a one hit wonder summer.

Both of them were at 100 on the 2:00pm 5-minute ob. BWI had also already cracked it earlier as seen in the 6 hour max. Amazing run here.

It’s funny that you’ve been beating me all summer, but the last two days I’ve passed you up. 99.9 here at the moment.

High so far are at least: DCA: 98 BWI: 97 IAD: 96 98.4 at home

Latest HRRR…is not a great convective model in weakly forced mid-Atlantic summer conditions

The 850s aren’t as supportive today, but DCA may grind out a 100 anyway.

Yesterday's average temp of 92.0 degrees (104/80) slots in as a tie for the 5th hottest day in the DCA climate record.

85 at 6am at DCA. Looks like the overnight low was 83.

95.2 at 2:19pm. From the solar measurements it looks like some clouds developed. DCA was similar.

Evidently it can only rain in Loudoun and MoCo now

90/75 at 10:40pm!

Derecho day was still 103 at 6pm, but caught a river wind and dropped to 96 at 7pm. Bounced back to 98 at 8pm. https://www.wunderground.com/history/daily/us/va/arlington/KDCA/date/2012-6-29

99 at DCA at 7pm

Reminder on rounding the 5 min obs. The 104s should be legit.

104 at DCA would be a tie for the 6th hottest temp on record (106 twice, 105 three times)

102.7 at home. Wow.

Exactly. On these days we are usually watching the cu field and seeing when they might come by. Just relentless today.

First ever 101 on my station. Even on the crazy 106 IAD/105 DCA day in 2012 I didn’t make it. The drought makes all the difference.

6 hourly highs BWI: 103 DCA: 102 IAD: 99

100.2 on my station. Fractions away from my all-time high set in 2011.

If the Outer Banks had crappy clay/rock fill instead of sand.

Straight up. Faster than the system can update the high temp.

Will be interesting to watch the rise today. Starting several degrees cooler than yesterday, but should make up ground quickly.

Tip top shape this year

Complete whiff, but the outflow is pleasant
