Note: I had a list compiled from Wikipedia 2019 data that I updated with new numbers today. Only one state, Colorado, had a new high temperature record, set in 2019. But the past climate keeps changing -- six states had revised records (that were set long ago) -- mysterious revisions. Didn't people know how to read a thermometer 100 years ago? Ye Editor
