The Fall Equinox is on Saturday and thus starts the astronomical fall season. The weather recently has certainly felt more like the middle of summer than early fall recently, but thankfully a cold front swept the state clean of the hot and muggy air overnight. Of course the definition of the seasons is arbitrary, but if one considers the warmest consecutive 91 day period each year as the summer season then the start date of the fall season can be determined. The featured chart does that calculation and shows that the trailing 91 day average temperature peaked back on 21 August! That means we have had a month of the fall season already! The bottom two panels show some metrics on the fall season and the average number of days shown in the bottom panel show the fall season averaging only 84 days. This weekend looks to be awesome fall weather, so enjoy it before winter comes.
