There are three(3) things below that bear reading. First is the NWS May summary for Flagstaff. It was quite warm…until the end. In the end we had record breaking rain and cold. Quite an interesting month… a quandry!
Below are temperature graphs for the month. They are self-explanatory.
It appears the trend will continue into June. Maybe not as wet, but probably more clouds than usual. Phantom Ranch had a record low temperature, yesterday.
