Our heatwaves almost always follow this pattern: - First day under performs - Second day comes in about as expected, usually topping out at 98-100 - Third day we set an 80 degree low (though we just missed today) - Third day over performs and we tie/exceed the highest temp of the heatwave - Evening thunderstorms on the third day wipe out the 80 degree low

It was. It seems like lately we hit 90 by 10am more frequently while topping out at 98/99. That last degree or two has been hard to get. I’d probably reframe it now as being at 90 at 10am is the latest you want to see and still have any shot. Ideally you need to be there earlier.

What you’re probably seeing are the 5 minute obs that are being converted to Celsius, rounded, then converted back to Fahrenheit. Only the hourly obs are shown in the original Fahrenheit. 97 could be 96 or 97. 99 could be 98 or 99. 100 is 100 or 101.

DCA hit the benchmark of 90 at the 10am ob.

There are a few standout years (1907, 2003) but this is one of the coldest 9-day stretches we’ve seen during the end of May/beginning of June time frame and ranks up there as one of the top. 1907 was incredible. The cool pattern started May 20 and continued into mid June. DC had highs of 53, 54, 57, 59, and 62 in June alone.

Canaan Valley dropped to 18.

The best part about this winter is DCA finally learned how to measure snow. Their measurements are finally close to those in the area.

Lol, I’m at 35. DCA 37.

Good precip orientation for the metro area. It’s a shame we can’t do this in snow storms.

DCA up to 28. Might crack freezing today.

Well modeled too. Every model showing darkness until about 7am. Except the RGEM which is off on its own showing sunrise around midnight.

We measure on top of existing snow pack, right? If so, I’m pretty much there!

Another 2” this evening puts my total at 8.2” a few miles west of DCA.

Snow has picked up again in south Arlington.
