MIKE MOSS SAYS: Cathy, I don't have a handy example of that or a readily available source to verify if it has been the case. I suspect that if you allow for the high and low to be rounded off to the nearest whole degree, there has probably been some station at some time that pulled off that trick, which would require of course that the temperature stay the same the entire calendar day. I would speculate that this would have the best chance of occuring at certain times of year near the poles, and on some small tropical islands.
