Today was only our 2nd above normal day here in Western Chester County PA (76.4/51.7) over the last 12 days. I have been telling my local Chester County farmer followers for the last week to expect another well below normal stretch to follow the very brief warm up this weekend as we move into October.....still thinking any freeze concerns and basic end to the growing season over most of Western Chesco which is over 600 ft will wait...till likely the middle of the month. This would still be a bit earlier than our normal 1st freeze for the Western spots in the county which is October 23rd (October 14th for Chesco below 600ft ASL)

Another record daily low max in Western Chester County PA yesterday...the old mark was 63.0 set back in 1991. This morning's low was 40.3

2nd consecutive record low maximum temperature here in Western Chester County PA. Today's high of only 61.2 eclipses the old mark of 63.0 set 29 years ago back in 1991. Down on the barrier islands on the Jersey Shore in Sea Isle City the high was only 63.3. Overall these readings are in line with normal late October readings than mid-September

Today's AM low tied another daily record at 40.3 matching the mark set back in 1999. Yesterday's high temperature set another record low max mark for Western Chester County eclipsing the old record of 62.0 set back in 1993

Yesterday's max temp of 58.9 just missed setting a record low max which was 58.0 set back in 1987. Today we have an excellent shot at a new record low maximum with the current record at 62.0 set back in 1993. Our AM low this morning again was no bueno for the 30's as we bottomed out at exactly 40.0. Of note today is the earliest date in the all time (all elevation) data set for the Western Chesco that we hit the freezing mark - with a low of 32.0 on this date back in 1956. That year also marked the shortest growing season for the local farmers as that season only lasted 119 days.
