Some of our colder valley locations saw lows this morning in the chilly 30's. The lowest was at Warwick Township at 37.4 degrees. The next couple of days will be seasonably cool with highs not too far from normal in the upper 60's but lows a bit below normal including some of those same spots tonight sinking into the 30's. We start a moderating trend starting Saturday that should last through the middle of next week before we turn much cooler again toward the end of next week. Our best rain chances look to be next Tuesday or Wednesday.

Happy Red October for those who celebrate - Go Phillies!! I will have the final September climate wrap up for Chester County later today, but it looks like we finished with slightly above normal temperatures and below normal rainfall. We have had 5 months with above normal temperatures and 4 months with below normal temperatures so far here in 2025. We are much cooler this morning with the chilliest spot being the 49.5 degrees at Chester Springs. We will see dry weather with below normal temperatures through Friday and then a nice warmup through next Tuesday before we cool down again during the middle to end of next week. As has been the case no rain in sight.

Who is ready for October starting tomorrow. We have seen summer like readings of 100 degrees and temperatures in the teens. We even occasionally see snow. Who remembers 2011 when between 5" to 9" of snow fell across the county? October Chester County PA records are below.

Today we should see temperature once again reach above normal levels in the mid to upper 70's. There will however be a noticeable lowering of humidity and dew points by this afternoon. We cool to below normal levels as we start October tomorrow with high temperatures across most of the county remaining in the mid to upper 60's for the rest of the work week. By the weekend we should see a warming trend with temperatures rising into the mid to upper 70's. There is almost no chance of rain for at least the next week.

Yesterday’s high temperature of 79.1 degrees in East Nantmeal (22 years of data) set a new daily record for the date the old high temperature record was 77.9 in 2019. While it was unseasonably warm yesterday…it was still much cooler that the overall county record for the date which was 90 degrees set back in 1945 in Phoenixville. Today and tomorrow will continue the unseasonably warm temperatures with highs both days well into the 70’s to near 80 in some of our valley locations. Our normal high temperatures here in Chester County for late September are in the low 70’s. We turn sharply cooler tomorrow night with lows by Wednesday morning in the upper 40’s to near 50 degrees. Thursday and Friday will be sunny but unseasonably chilly with highs in the mid 60’s and lows in the low to mid 40’s with even some 30’s across the valley spots. We slowly warm back up to normal temperatures by the weekend. Unfortunately, no rain chances this entire week.

Today will be our warmest day of the week along with some relatively high humidity for late September. Today’s highs will be in the upper 70's in the higher spots to lower 80's in valley locations. A couple of degrees cooler tomorrow followed by our chilliest weather so far this autumn season with highs by mid-week remaining in the 60's and morning lows well down into the 40's with even some 30's possible for our colder valley locations. We look dry through the entire week.

Any morning sun will fade behind clouds this afternoon. Some showers should start overspreading the area from south to north after 7pm this evening. Most spots across Chester County could see between 0.25" to 0.50" of rain. The sun returns tomorrow with continued above normal temperatures in the upper 70's. This will continue through early in the work week before we start a big cool down by the middle of the week. Of note you will see in the climate records below that 40 years ago today back in 1985 we experienced heavy rain across the area as a result of Hurricane Gloria.

Rain totals over the last 3 days include East Nantmeal 1.22" / Atglen 1.56" / Chester Springs 1.31" / Devault 1.73" / Glenmoore 1.20" / Kennett Square 1.74" / West Bradford 1.64" / Nottingham 0.93"/Warwick 0.57" and West Chester 1.13". We should see some sun today as we dry out and see humidity levels drop. Today should be the warmest day for quite a while. Highs will be well into the 70's to 80 degrees in valley spots. We start cooling down tomorrow and in fact by next Thursday some of the higher spots may struggle to escape the upper 50's for high temperatures. We should see lows well down into the 40's by midweek as we start the month of Red October - Go Phillies! Our only chance of rain looks to be Saturday night with another 0.25" to 0.50" possible.

You lost me with another climate forecast that will as have the others not verify "Even a one-meter rise in global sea level, plausible by 2100"....it is of course not plausible and in fact almost impossible to see a 3 foot rise in the next 75 years!!

I suspect even if we were to assume (which is a huge leap of faith) that these future climate model predictions were to come to pass....I suspect a change from an average annual temp of 56f (13c) degrees today warms by 4c as in the mid-Pilocene period to 63f (17c) would for folks in that area allow them to easily deal with your scary "unmanageable world" albeit with a longer growing season and less snow. The scam and hoax Trump speaks of are the very words and fear you trade in above. By using terms and images such as "consigned them to an unmanageable world" you are trying to scare folks into believing yet another in a long line of failed climate predictions. Again we are all still waiting for that firsts proven disaster that we can attribute to this scary climate change we keep hearing about.
