Overall, September continues to be the warm season month that remains most reliably seasonable and least likely to torch.
At SEA for example, 4 of the past 5 Septembers have actually been wetter than normal.
Well we finished September at near to below normal temperatures at all Chester County locations with the exception of the Glenmoore coop station - which recorded one of their warmest Septembers on record.
Of the 5 COOP locations only Glenmoore finished well above normal with an average temperature of 68.4 which is +1.6 degrees above the 30 year average for the month. This was also the 19th warmest September at Glenmoore across 67 years of data. Both KPTW Pottstown 65.5 degrees finished at -0.8 below normal and Phoenixville 66.6 degrees (0.7) finished with below normal temperatures good for 65th chilliest at Phoenixville with 131 years of data and 10th chilliest at KPTW with 25 years of records. Both KMQS Coatesville 67.1 +0.3 and here in East Nantmeal 65.4 +0.02 finished with slightly above normal temps with KMQS recording their 8th warmest September with 16 years of records and EN recording their 62nd warmest September with 130 years of records.
The week ahead looks great with well above temps....we could in fact reach 80 degrees across some lower spots of the county for the last time this year on Wednesday. Much cooler weather returns by next weekend.
