Heck Sam, we're only about 4400' elev and it was a total surprise it even got down to 37. I think the NWS was calling for a low of only 42 or so, and as was said on the home weather station thread they are usually pretty close.
Nothing near that low forecast for the next week or so, and we're going back up to 95 again. Bad thing about that, the electrical Co-op will be doing some work out here Tuesday and shutting us down from 0830-1330. And it will be hard to cool the place down that morning as it's only supposed to go down to 54F overnight.
Might have to break out a non-Yeti ice chest for some of the stuff in the fridge. The chest freezer should be OK, it's stuffed with frozen stuff and has some moving blankets on it.
Good luck with your corn. And yep, first frost last year here was in early Sept.
