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.
