ChescoWx

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....

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!

Hottest day for a while today before storms tonight usher in some typical June temps to close out the week. Weekend looks a bit unsettled with maybe some more rain chances but not a total washout. Temps look to fall back to a little below normal to start the new work week. Chester County records for today: High 100 degrees at Phoenixville (1943) / Low 43 at West Chester (1899) / Rain 3.35" at Coatesville (1938)

Did you record a 90 yesterday? The high here was 78.2....today we topped out at 83.6 for the high here in Chesco...even by roof top station could do no better than 85.

I was quoted for an article written last week for the Chester County Local (see below). Fortunately my thoughts downplaying the model outputs were correct...as I suggested that the county would not see a 100 degree day. This despite the many models (hello Euro) and on line weather sources hyping the century mark as a possible outcome. As we always say we don't sweat or shovel model output!! Now, If the model was right....I would clearly not have posted this link!! LOL!! https://www.dailylocal.com/2024/06/17/scorching-temps-on-way-for-chester-county-but-no-100-degree-days-says-observer/

No matter what climate alarmists find and post there is just nothing we observe happening in today's current climate that has not occurred before....no matter how often they say unprecedented etc.

Once again Charlie I will produce the source data. Below is detailed map coordinates and elevation of all NWS/ AWOS / MADIS stations included in the data set. All of the data produced is derived exclusively from this data set. There is clearly a station mix like the older County data favoring the relative lower elevation sites with 16 of the 27 (67%) below 450 ft in elevation with just 11 at above that level. In addition of the current 15 stations moving forward 8 of those 15 are below 450 ft asl. A great go forward mix of higher and lower stations.

A beautiful morning across the county with many spots dropping into the comfortable 50's for lows. We see temps begin to warm again today and especially tomorrow with highs tomorrow again touching the 90's in many spots. Some shower and thunderstorm chances tomorrow night as another cold front passes and will cool us back down to near normal temps to close out the work week. Chester County Records for today: High 101 at Phoenixville (1943) / Low 45 at Coatesville (1902) / Rainfall record was set just last year (2023) at Chester Springs with 1.82" of rain.

From my friend Chris Martz some great perspective data! "Well, it was hotter during June 1853 as an “unprecedented, climate-fueled heat dome” set up shop over the eastern half of the country. On June 20, 1853, Washington, D.C. hit 100°, which eclipses the “official” (since 1872) record high of 99° from 1931. The following day was 97°, and then on June 22, 1853, D.C. again topped 100°, capping off at 102°, which would break the “official” record of 101° from 1988, and eclipses Saturday’s 100° reading at DCA. The same day, Detroit, Michigan topped off at 106° and so did Fort Brady (present-day Sault Ste. Marie). The “official” daily record high for June 22 in Detroit (1874-present) is 98° from 1988 and Sault Ste. Marie’s (1888-present) is 90° from 1975, so the high of 106° on June 22, 1853 shatters those. It also eclipses Detroit’s “all-time” June record high of 104° from June 28, 1934 and June 25, 1988 and Sault Ste. Marie’s of 93° from June 27, 1901; June 30, 1927: and June 26, 1983. And, these 106° highs shatter Detroit’s “all-time” record high of 105° from July 24, 1934 and Sault Ste. Marie’s of 98° from July 30, 1916; July 3, 1921; and August 5 and 6, 1947."
