16 of our last 20 days have featured below average temperatures. Today will be another below average day before we start a strong warmup with temperatures by Tuesday approaching 90 degrees across especially the valley locations across the County. A cold front will cross the area later Wednesday with a chance of some showers. Following that front we should see temperatures fall back closer to normal levels by the end of next week.

Quite the difference my NWS point and click had the warmest being Tuesday and only 87 degrees...Enola has 94 on Tuesday

We picked up 0.44" here in East Nantmeal since last night, Cool and breezy today before we start a nice warming trend. Some lower valley spots may touch 90 by next Tuesday. Higher ridge locations are likely to remain in the mid to upper 80's. We will likely see a return to cooler temps toward the end of next week. Our next chance of rain looks to be toward mid-week.

I actually did just such a deep dive into for example the NWS COOP station at Coatesville 1SW below shows any bias would only have potentially been present from 1910-1921. So not significant based on the 89 years of history for that station.

If modeling is correct certainly no long lasting warmth through June at least

I have compiled the climate averages based on the NOAA calculation of Climate Normals for the philly burbs of Chester County PA for a full year with 30 year averages updated every 10 years. The first base period was from 1901-1930 with our most recent being the current climate base of 1991-2020. You can see our warmest base climate normal occurred back in the 1921-1950 and 1931-1960 periods.

Mostly cloudy today with highs not too far from average near 70 degrees. Some rain showers and maybe a thunderstorm late tonight ending toward rush hour tomorrow. We fall back to below normal temperatures both tomorrow and Friday before a big warm up with temperatures across the county reaching around 80 degrees on Saturday and the mid to upper 80’s on Sunday and Monday. Next Tuesday should be the hottest day with temperatures especially in lower valley locations possibly touching 90 degrees. We will get cooler again by the middle of next week.
