There has been a remarkable difference this summer - 45 days above 90 here, several days in August that were above 95. I recalibrated my station after it needed new parts...I have to believe it's accurate as I've been spot on with the Wunderground stations around me.
Other odd thing is that I'm SW of Harrisburg, and on most of the hot days the wind direction has been S or SW...coming from the opposite direction of Harrisburg from my location. (mostly blowing straight from the total boondocks of daxx-land in East Prospect)
