A Long Streak Ends

With clear skies and a weak intrusion of slightly cooler air from the northwest moving in last night (hence the smoke), we reached a minimum temperature this morning of 65ºF.  The average minimum is 66ºF, so if my numbers are right, this is the first day since June 23rd that we have had a below average minimum temperature.  That's a run of 39 days.  I wonder what the record is?
