The Autumnal Equinox occurred early Monday morning on September 23rd. Reading’s 40.3° latitude still results in 12 hours and 8 minutes of daylight so not quite the equal 12 hours day and 12 hours night typically quoted. NOAA does state the first day of Fall actually varies from September 21st through September 24th depending on the location.
Considering our recent weather pattern you wouldn’t know it was Fall. Our temperatures have been mid 80’s to yesterday’s station breaking record of 90 °F. September, to date, has produced just 6 days of measurable rainfall and the station is more than 1.5″ below normal for the month. The next 10 days are expected to be generally sunny with temperatures above average and no rain.
