Truth! Only long running climate data works!

Due to multiple requests below for comparison I have added the recast National Centers for Environmental Information (NCEI) temperature data that includes the chilling adjustments to the older data. That chart is now below the actual raw data. I split our weather database almost down the middle to compare how our climate here in Chester County has changed compared to the first 66 years of climate data (1893-1959) vs. the last 67 years of data (1960-2025). With the actual data we see that 7 of our months have trended cooler - 3 have trended warmer and 2 have remained about the same. Overall, on an annual basis the actual raw data has trended cooler by 0.2 degrees during our most recent half of climate data 1960-2025. However, once NCEI applies their adjustments it paints a very different picture. We see clear warming in each and every month during our more recent climate history from 1960-2025. This aligns well with the expected warming narrative.

Well if AI says it's so.....

A Freeze Warning is in effect tonight through 9am tomorrow morning. Be sure to protect any tender plants by late tonight. In my 22 years here the average date of my last freeze has been April 10th. Valley locations across the area have averaged later last freeze dates. High temperatures today will be almost 20 degrees below normal temperatures in the 40's. We start a warming trend through the rest of the work week before chilling down and turning wet for the weekend.

The correct answer remains as always - climate change!! LOL!!

If looking to stay away from that summer like heat from this week....the ensemble models keep us below normal into May.

A much chillier day underway with showers across the area. We have already picked up 0.12" here in East Nantmeal with a little more on the way with shower chances continuing till about noon. Today’s temperatures will run about 20 degrees colder than normal with highs struggling to escape the 40's. Unseasonable cold tomorrow with highs again in the 40's. A freeze watch starts tomorrow night at midnight with lows by Tuesday morning in the low to mid 20's in the colder valley locations. We start a slow warming trend that lasts through the week with temperatures by Thursday near 70 degrees.

For those folks down the shore - the chilly ocean water temps working their unfortunate magic for folks down in Sea Isle City NJ for Girl's weekend....highs in SIC have not moved much from around 50 degrees all day. The beauty of coastal climes in the Northeast US in spring! Can hardly see through the fog and marine shank!

Today will be our last above normal day though Wednesday. Today’s temperature will approach 70 degrees especially the further west you go. Tomorrow temperatures will struggle to escape the lower 50's. We should see some showers along the cold front during the morning tomorrow with between 0.10" to 0.40" of rain possible. By Monday temperatures in the higher spots will likely stay in the 40's with a freeze likely Monday night into Tuesday morning. We start to moderate with temperatures back to several degrees above normal in the low 70's by Friday.
