When we were house-searching a couple of years ago, I would have loved to have been able to move to someplace more local to where I grew up like East Nantmeal. However we were quickly priced out of Chester County amidst the huge housing bubble. So while I'm happy for you that your summer was "normal", East Nantmeal is simply not representative of the region as a whole, you must be aware of this. However however, it IS still interesting, given your geographic and elevation disparity with most of the rest of us. It would seem to me that a mere ~400' of added elevation can produce a statistically significant result... for now. I'm still waiting for a list of those weather stations you mentioned in your previous post.
FWIW, I've recorded 42 days above 90° IMBY thus far. My readings have shown enough correlation over the last two years with other local obs that I trust them.
In other news, I'm looking forward to publishing my updated IMBY charts tomorrow. Do you guys mind seeing them here, or would it be better to start (and maintain) a separate thread?
