GDD calculation error?

Brian,
I’m surprised to see the Growing Degree Day calculations going through the roof, sometimes more than 500 degrees in a single day! Perhaps there is something wrong with the calculations?

Brian,
I think this came in while you were storm-chasing… Did you ever get a chance to look at this?
I suspect the GDD is getting its temp reading from a sensor input that is not being used. Is that possible?
