Smoke may insulate our overnight lows. It's 12:15 am and the Baltimore City mesonet site is at 84°.

Took our trash out about an hour ago.  Our driveway is very long so I use a helmet flashlight to light the way.  Could see the smoke and other suspended particulates drifting in the air.  Looked like the mist of a dense fog, but with smell.

the midnight 5min ob at DCA is 90 with 3mi visibility.  IAD is 87 with 2.5mi

It’s nasty out there. Smell is worse than I remembered from a couple years ago. AQI is around 150 so we still aren’t in the worst of it.

To be clear, IAD has never recorded an 80+ low for any day.  The morning low was 81.  The question is whether it falls below 80 by the end of the day.  It did drop down to 79 last evening when the winds went calm, and then rose again before midnight.

IAD is 85F at the 1am ob - officially 96/81 on the day.  First 80+ low

DCA is 86F at 1am - another 80+ low there (3 so far this year) - 98/81.
