One last mild above normal temperature day today before some showers arrive after midnight tonight and turn us back to below normal temperatures for the rest of the upcoming week. Rain tonight looks like between 0.25" to 050" across the area. The only other chance of rain this week looks to be Tuesday night. Highs looks to be in the 50's and lows in the 30's for much of the late week period.

Got it! You can't find any proof in the Chester County data to undermine the quality of the data....unless we go hundreds of miles away - check!!

Of note today back in 1972 we recorded our earliest measurable snowfall in the county area. Between 1" to 3" of snow fell across the higher ridges of NW Chester County. Interestingly that winter of 1972-1973 ended up being the least snowy winter in County history. In fact, that is the only winter season that no measurable snow was recorded at Coatesville. No snow chances this season till next month. Today we warm nicely well into the 60's with low to mid 70's by tomorrow as we enjoy a little Indian Summer for those spots that have already seen a freeze this season. Rain chances to ramp up by Sunday night into Monday morning. We then turn chillier again for the upcoming work week.

You keep making the rookie mistake of trying to bring unrelated stations not anywhere close to the county in question. Some of those you reference are 25 to 40 miles away....that does not improve a poorly constructed argument or address the facts proven above.

Don the problem is your reliance or let's call it your faith (which is not science) that "IF what is modeled, proves accurate ...but conversely and it is certainly possible IF what is modeled proves inaccurate (which is of course not beyond the realm of possibility) the consequences you fear of what from today's vantage point in your world view seems foreseen and avoidable - in fact never ever comes to pass...would obviously mean there were in fact no consequences that we needed to avoid in the first place. Do you see why you are being called out by myself and others for your so called "thesis of doom" post?

Bravo! an excellent post! Too often folks bring in politics where it has nothing to do with the political whims of a democratic society like here in the US. Thank you!!

Is this thread not for climate change on a world wide, United States, State Level or County basis? I do present climate change thoughts on a county basis. For example I posted real climate stats showing climate change across Chester County regarding the number of 90+ days. That is a climate post correct?

Now that we are done with any 90+ degree days. Below is the by-decade trend of the average number of 90+ days across Chester County PA from the 1890's through the 2020's. There is a clear decline at all elevations in the number of such hot days. In fact, the 2020's are trending to be the 2nd lowest number of average 90-degree days behind only the 1970's.

The mistake you made in the chart is the actual 1st full year at the new location in Coatesville was 1949. A full one-third of 1948 was actually at the old location. When we look at the actual data for that first full year following the move which was 1949 - you can clearly see that temperatures far from cooling as you keep saying in reality actually warmed by 2.2 degrees - no cooling at all. You would think moving from what you called a "UHI" location would have resulted in cooling - it of course did not! Also of importance all 3 stations warmed that year! And look at those altered NOAA temperatures for the county....what station in 1945, 1946, 1947 was as cold as that ghost station they used? Answer of course absolutey none - it's a ghost for Halloween!!

Some of our colder valley locations saw temperatures again this morning below freezing. Here in East Nantmeal on the ridges of the Welsh Mountain anticline at 685 feet ASL we only got down to 39.1 degrees this morning. Another below normal day today with ridge locations struggling to get out of the 50's for high temperatures. We do warm over the weekend with temperatures reaching as high as the low 70's on Sunday before we begin another chill down next week with below normal temperatures by mid-week. We have some good shower chances by later Sunday into the evening.
