Fun cyclical climate change stat of the day - Did you know that the average number of heatwaves in the U.S. have decreased by 27.9% since the beginning of the 20th century?

Today will be the last day for over a week with above normal temperatures in the upper 70's to near 80 degrees. We fall off to the upper 60's to low 70's tomorrow and with near record setting low maximum temperatures possible both Tuesday and Wednesday. High temperatures both of those days will struggle into the mid to upper 50's. Those temperatures are typical for November 10th! In addition to the unseasonable chill this week it will also be very wet. Rain chances increase by Sunday, and chances remain each and every day of the new work week. The in-house ChescoWx model predicts over 4 inches of rain this week!

Today will turn noticeably more humid with temperatures around 5 degrees above normal in the lower 80's for most spots. We could see a brief shower in spots this morning. A cold front crosses the area late tonight with maybe a couple showers. We turn a bit cooler and less humid tomorrow and Saturday with near normal temperatures. Rain chances increase by late Saturday night and look to last through the day on Sunday. We turn unseasonably chilly to start the new work week with my backyard ChescoWx model forecast keeping afternoon highs both Tuesday and Wednesday in the upper 50's.

Our beautiful autumnal weather continues with temperatures warming to a few degrees above normal both today and tomorrow with Highs not far from 80 degrees. We then start a sharp cooling trend over the weekend and into the new work week with temperatures by next week according to the ChescoWx forecast only in the low to mid 60's by the start of next week. The NWS forecast has those days about 10 degrees warmer – let’s see who is closer. Rain chances ramp up by late Saturday night into Sunday and Monday.

Below is a snapshot of both the raw actual annual average temperatures and the NCEI adjusted for Chester County PA over the last 10 years from 2016-2025. Both trend lines show a cooling period is underway but neither line is statistically significant. Could this indeed be the start of our next cooling cycle in our never ending cycle of climate change?

Thanks Mike!!

Plenty of 40's for lows this AM across the area with our overall chilliest morning since back on June 2nd. The coldest reading was the 42.7 at Warwick DEOS. Below normal temperatures look to continue today before we start a warming trend that peaks on Thursday before we turn cooler again for the weekend and looking ahead we see some unseasonably chilly air by early next week. Highs may not get to far above 60 degrees for some of the higher spots by next Tuesday. Our next rain chances hold off till Sunday.
