It's even up to 82-83 up at Davis, WV. That's about as hot as it gets up there.

Yeah, that is pretty impressive! I was checking some of the readings from the higher elevations. Bluefield (WV) Mercer County Airport, at nearly 3000', reached 90 today. It rarely gets above 90 there -- last summer had several, but the majority of summers seem to top out in the high 80s.

This was the earliest occurrence of 90+ on record. In fact, the previous earliest 90+ reading wasn't until June 18! Records at the airport there date to the late 50s.

Evidently the Davis VP's have a high DP bias. Mine topped out at 78 just before noon. Am wondering if my lawn location near a garden is helping that too. And just like the hot days last summer, DCA was exactly 5 degrees warmer than my yard.

According to the Davis VP, High was 98.2 with a suspicious 110 degree heat index reading. The station is in the shade though.

Now lets see that Derechio :P

The sea breeze boundary doesn't want to come east looks like.

I had that problem with the Davis VP2. After calibrating it with a second hygrometer, I found that I had to offset the RH by adjusting it down about 12% in the summer and it's seemed pretty accurate since then. My station is in the center of a large (4 acre) lawn with corn fields all around.

92 here for the high for the second day in a row. HI briefly reached 101.

Mine seems to read 1 or 2 higher on the DP too, but I attribute that to the lawn and nearby trees, and is reality at my location. My DP also fluctuates like a heart beat monitor +/- 3-5 degrees during the day. I have the fan in my unit too.

I just checked and all the PWS's in my area have the same DP as mine or within 1 degree. Most of them are Davis stations so I don't know.

My highest reading today was 93.5, with a heat index of 107.

I believe the Bluefield Chamber of Commerce gives out free lemonade whenever the temp hits 90 or above. I wonder if they were ready for it today....
