Funny enough, that's exactly what the HRRR is showing.

Hopefully the gif works. Fun representation of the temps with the impact of the convection later today from the RRFS.

Temps running about 1-2 degrees lower than yesterday through 9am.

Another 84 for a morning low at DCA, but whether this one holds through the day is more questionable than yesterday.

I’d be more tolerant of opposing opinions if the question was “what should we do about it?” There are serious policy questions about the impacts on society (including costs) of transitioning to low-carbon energy. If the debate was cost vs benefit, that is an extremely healthy and useful discussion.

Stop the count! Seriously, though, I’m going to rack up some departures today since I went too cool so it is still wide open.

“The preferred narrative”. Dude, stop.

Not gonna make it at my house. Too humid. Pair of 99s.

Just drove up to the Fredrick MD area. Car thermometer noticeably tracked the mesonet, with lower temps in the slightly higher elevations of MoCo, and then back up over 100 going down towards Frederick.

Noon obs: DCA: 97 BWI: 97 (has been to 98) IAD: 93

95.4 so far at home. The flyovers have begun and apparently I’m on the flight path!

84 at DCA! All-time record tied. IAD falls one short at 78.

We'll see in 15 minutes or so whether some all-time records have been tied. ================================================================== *** ALL-TIME RECORD WARM LOWS *** ================================================================== Baltimore 83 (set on Aug 05, 1930 + 2 other times) Washington 84 (set on Jul 24, 2011 + 2 other times) Sterling-Dulles Airport 79 (set on Aug 08, 2007) Baltimore Downtown 88 (set on Jul 22, 2011 and Jul 10, 1993) Annapolis 92 (set on Jul 07, 1994) Hagerstown 86 (set on Jun 15, 1899) Martinsburg 86 (set on Jul 21, 1930) Charlottesville 85 (set on Aug 07, 1918)

3rd highest 850mb sounding temp on record is extremely impressive.

Feels like a night where we put up 82 for a low at DCA

BWI 101

98.4 has been my high. Related to the contest, Salisbury is getting into the heat game with 97. Richmond is only 95, but they are hanging onto the upper 70s DPs while we are down to low to mid 70s for the most part up by DC.

They’ll get a late kick out of the west and push them over the top.

BWI wins the race to 100

Yikes

I was assuming that we were looking at more of a 2024 or 2010 like heat where the focus wasn’t on the humidity, but this is damn near 2011.

IAD is almost certainly going to get their record daily high today. This airmass isn't historic enough to challenge all-time highs, but daily records at any time in July is impressive. And the lows will challenge records too.

10:30am and we have our first couple of mesonet sites hitting 110 HI.

One good thing that I'm seeing is that the new RRFS seems to be handling this a lot better than the HRRR. The HRRR is out of control with mixing out the boundary layer, with places like Fredericksburg with something like 108/55 tomorrow. Conversely, the RRFS is a reasonable 102/69 for tomorrow.

My annual warning for reading the 5-minute obs. Because of rounding, a 5-minute reading of 99 could mean 98 or 99. A reading of 100 is 100.
