Who cares about my house?? It is an insignificant non issue in the data analytics - Charlie you do get this correct??

The machine based revisionist history of our climate in Chester County continues to more modern times. Just last August 2023 - NOAA/NCEI increased the average temperature by an entire 1.0 degrees to 73.1 degrees for Chester County PA from the actual average of 72.1 degrees. Why was this done? Well of the 16 current stations in the county only 2 of them.....KOQN Airport (74.2) and Phoenixville (73.7) (always our warmest stations) were above 73.1. Was there a time of observation adjustment? Poor equipment? Siting issues?? Keep in mind they cooled every single year from 1893 thru 2005 and have now warmed each and every year since 2006.....

And you of course cherry pick one month out of 1,572 months of data.....

Most of the County has picked up some beneficial rain overnight. Ranging from as low as 0.49" at the Coatesville Airport to as much as 1.88" down in West Grove. Southern spots were for the most part near or over 1 inch while folks in the north were closer to the 0.50" to 0.70" of rain. We start the day muggy but a sharp cold front will cross the area between the 3pm to 5pm hour with another round of possible heavy storms and t-storms. Some spots could pick up another 0.5" to 1.00" of rain. Much cooler tonight with lows into the 50's and pleasantly cool to start July tomorrow with highs struggling to escape the mid 70's in the higher spots of the County. Chester County records for today: High 103 degrees at Phoenixville (1934) / Low 46 at Devault (1988) / Rain 2.95" at Glenmoore (1973)

Clouds on the increase today and a good bit warmer than yesterday with temps reaching the low to mid 80's. Rain chances increase late tonight through tomorrow. Best chances for heavier rain would be tomorrow night with a cold frontal passage. Much cooler again for Monday with temps slowly warming as we head toward July 4th. Chester County records for today: High 103 degrees at Phoenixville (1934) / Low 45 degrees at Coatesville (1988) / Rain 3.88" at West Chester (1973)

The true silly part is believing that using data from outside the county being observed makes any sense at all!! I will continue to rely on the actual factual stations in the actual factual county we are observing and not rely on a machine adjusted fake number that totally discounts all of the confirming similar data validated by the NWS at the time of observation in the county of interest.

Most spots dropped well down into the 50's last night with the chilliest temp the 50.9 degree low at Warwick Township. A great day on the way with low humidity as highs possibly not escaping the 70's in the higher spots in Chester County. Rain chances ramp up by tomorrow night and into Sunday before sunny and cooler again to start the new work week on Monday. Chester County records for today: High 101 degrees at West Chester (1963) / Low 47 degrees at Morgantown/Elverson (1970) / Rain 3.33" Glenmoore COOP (2006)

A nice couple of days to close out the work week with near normal temps in the low 80's with lows tonight in the comfortable 50's for most spots. Rain chances increase Saturday night into Sunday and then after a cool start to next week a slow moderating trend. Chester County Records for today: High 100 degrees in Phoenixville (1943) / Low 46 also at Phoenixville (1965) / Rain 4.54" at West Chester (1938)

So let's take all of the stations down to an average temperature lower than any station ever recorded for all of these years. How exactly did NCEI NOAA arrive at the need to make up a number for the county and make it lower than any thermometer almost each and every year? . Example for 1945 they somehow decided lets take the Chesco temp down to 2.8 average degrees BELOW what any station in the entire county actually reported that year. Where is the supporting calculation?? Charlie can you supply the detail for this large adjustment??

So you're saying you think Phoenixville had problems but maybe not any of the other sites? So heck lets adjust the average temperature at all 4 sites to a level below what any of them actually reported because of finding one site that just might have had a warm bias.....that of course makes zero sense! With your analysis you are never able to actually explain what the adjustment should have been and the rationale for each individual site. For example tell us at each site.... In 1903 Phoenixville should be adjusted by 1.2 degrees / Coatesville adjustment should be 0.4 degrees / West Chester 0.7 degrees and Kennett Square 0.3 degrees.

By the way Charlie no clue where you got the 2 degree difference over the period of record, Glenmoore COOP . The actual average over the POR is EN 53.0 and Glenmoore COOP 53.7 - below is the actual annual average temp by station comparison by Year for 2004 thru 2022 with EN top and Glenmoore COOP below - not any year has any material differences at all! 52.2 53.1 54.3 52.7 52.5 51.8 53.3 53.3 54.2 51.7 50.4 52.7 54.1 53.9 53.4 53.6 54.7 54.6 52.6 53.6 53.8 54.4 52.7 52.2 51.4 53.7 53.9 54.7 52.1 50.7 53.2 54.2 53.8 52.9 53.2 54.1 54.0 52.5

18z NAM saves us from drought!!! (if only I believed it)

The Reading Airport thermometer issue has really become more evident over the past 4 years. Things looked about right before 2019. But lately even though KRDG is north of Chester County... when compared to the 6 NWS/MADIS stations across Chester County at a similar elevation or lower (5 of the 6 are actually lower than KRDG). Reading has still run higher (red)than these and all 15 stations in Chester County since 2020. In fact during the last 2 years the average annual temp there is more than 1 degree warmer than any station in Chester County....it might be time to get someone up there and do a health check....

Sure with data since 1970.....c'mon man!! LOL!!

I am old enough to remember our climate did not begin since 1970!!! LOL!!!!!!

There were a lot more low elevation stations in the 50's....we are much more balanced with the cooling from the 1990's to the 2010's

Nope! no comment on the world only Chesco....i am sure someday we too will realize the same scary climate change and all of those horrible unprecedented events we are seeing occurring across the planet.

Below is the by decade split of average temps for complete decades since the 1950's sorted by elevation above sea level. Low stations are below 450 feet above sea level. As we typically have seen the temperatures have been very cyclical in nature with cooler decades followed by warmer rinse and repeat. The lower elevations during the 2010's were within 0.2 degrees of the 1950's....both the higher and lower spots have actually cooled a bit since the 1990's peak warmth.

Great question!! I guess those rapid changes are clearly just not penetrating the climate fence that is securely around the Chester County PA border....

Below is the by decade split of average temps since the 1950's by elevation. As expected very cyclical in nature with cooler decades followed by warmer rinse and repeat. The lower elevations during the 2010's were within 0.2 degrees of the 1950's....both the higher and lower spots have unsurprisingly cooled a bit since the 1990's peak warmth!

Because we are all still waiting for the first actual weather event attributed to climate change that has not occurred before.... or even if you could point to more frequency of scary climate events that never occurred before. Boy that cried wolf syndrome in full force here!
