     But it was 25F on the morning a couple days before the summer
solstice?  Doesn't leave you much of an observing window!
     In the autumn post-monsoon season, roughly after mid-September,
the daytime temps stay fairly warm while nighttime lows drift steadily
downward.  Mean date of the first frost in Flagstaff is in the first
week of October.  Then about mid-October things really start getting
cold day and night.  Usually no significant snow until Thanksgiving,
likewise more cloudy statistically after mid-November.
