I'm guessing Mr. Wind came and messed with your smoker. :mryuck:
I don't have a clue what when on with the temps. Probably could have been several scenarios. While the WSM/UDS/ETC. usually don't need fancy electronic termos and fan controllers, there is always that 1 in 10 times that something doesn't go right and they sure come in handy. A Maverick with an alarm would have been handy.
