So I asked AI who is the best source of weather / climate data for Chester County PA? Can AI be wrong??

Several degrees cooler today and much less humid. Highs will still be several degrees above normal levels. Much more humid again tomorrow before a strong cold front crosses the area tomorrow night. We should see temperatures falling back below normal both Monday and Tuesday before we warm up again toward the end of the week. Shower chances increase tomorrow afternoon into the evening with the cold front.

We are only running around 80% of normal rainfall for the year to date here in East Nantmeal. It looks like we should see at least some showers and thunderstorms today that could give us some welcome rain. A heat advisory goes into effect tomorrow with highs both Thursday and Friday in the low 90's with increasing humidity. Shower chances will be around both later in the day Thursday and Friday. The weekend looks cooler but still warm before we turn much cooler to start the new work week. Temperatures both Monday and Tuesday may only be in the 70's for high temperatures.

There are some who believe our nightime lows are getting warmer during the summer months. The actual data sees no such warming - almost flat since 1893!

Wonder what is going on at KRDG since 2021?? Further north higher elevation than Phoenixville but now warmer than the Chesco warm spot.

I love when climate zealots simply eliminate stations they deem absurd....LOL!
