That outdoor temp would be just shy of 50 C. It was probably only about 83 outside when this was taken. I had just put a new battery in the remote and aired it out, because it was showing 20 degrees low; now it's reading really high. The hottest day recorded in Cleveland, OH is 104; Akron, OH recorded 101 in the same year (1988). Time for a new unit. This one is 15 years old, so we got our money's worth. I have been reading reviews, and it seems the new ones either work, or die in 4 months; nobody makes a "good one" anymore because they would be too expensive. Oh well. The Wife love to have these; she is always worried about what to wear outside, especially in the winter. Maybe I can get one with a humidity display as well. No, I don't have a point. It just cracks me up to walk by the back door and see readings this high.
