Below is the average July temperatures by decade for complete decades in Chester County since 1900. The actual averages are in blue and in red you can see the machine adjusted NOAA/NCEI revised averages. These adjusted averages as we have noted before are continuing with their consistent chilling of older decades and now the warming of our most recent decades. Of note in just the last 3 years 2020-2023 they have already adjusted the July average temperature up by 0.7 degrees for this decade of the 2020's...this includes the massive 1.1 degree warming they applied to July 2022.

You sound scared.....and I would have to put you in the above defined "doomer" category. You sound kind of similar to a certain climate activist....

That should not be a state record with such an obvious error. Just to add other stations bolded to the above post: July…1966 Philadelphia…104° Phoenixville…104° West Chester 105 July….1936 Philadelphia……104° West Chester 105 Coatesville 104 Phoenixville…....111° July….2010 Philadelphia….103° Phoenixville…..103° West Chester 102 Glenmoore 101 July……1995 Philadelphia…..103° Phoenixville…..100° Chadds Ford / Devault / West Chester 100 July……1930 Philadelphia…..103° West Grove 103 Coatesville 102 Phoenixville…..106° July…..1988 Philadelphia……102° Morgantown/ Honey Brook / West Chester 101 Phoenixville……99° July…..1954 Philadelphia….102° Coatesville 100 Phoenixville…..104° July…….1917 Philadelphia…..101° Coatesville 101 Sadsburyville 100 Phoenixville……99°

What makes an alarmist or doomer are the folks who continually state that "the climate crisis is an existential threat to the world" They will then usually conflate weather events with climate change and tout these events as "driven or fueled by climate change" "unprecedented heat or floods" but of course when we look back at climate history we find few events have been unprecedented during our current warmer cycle. If our climate warms by 2 more degrees over the next 100 years the earth will handle it.....just as it has always effectively and efficiently handled the past warm and cold cycles.

Happy Independence Day! The first 3 days of July have been the chilliest start to July since back in 2010. That will change today as temps rise back above normal with highs well into the 80's with a 90 degree reading possible in lower spots of the County. Rain chances increase this evening and we will see off and on shots at rain through late day on Saturday. Not a total wash out though. Chester County records for the 4th of July 105 degrees at West Chester (1966) / Low 42 degrees at Phoenixville (1986) / Rain 3.70" at Honey Brook (1973)

79 over in East Nantmeal

Most spots in the county for the 3rd straight morning reached the 50's for low temperatures. This already exceeds the amount of sub 60 degree lows we recorded last July. Out temps begin to warm through the rest of the week. Shower chances increase and just might interfere with some firework plans tomorrow evening. The best chances of rain are tomorrow night and again on Saturday. Daily Chester County records for today: High 104 degrees at Phoenixville (1966) - of note 8 of the 9 stations at the time exceeded the century mark on that day - only West Grove at 98 degrees stayed "cooler" / Low 45 degrees also at Phoenixville (1957)/ Rain 3.19" Coatesville (1978)

I suspect the problem with the forum is what is always the right answer....climate change did it!!! It is so so scary the almighty power it has!!! LOL!!!!

I broke the forum!

Credit and reference to Chris Martz for his 10 questions for the many climate doomers in this forum: Can you answer all of them?? ➊ To the nearest tenth of a degree Celsius, what is the “correct” global mean surface temperature (GMST)? ➋ What does a “perfect” climate look like? If so, when did we have one and what was it like? Usually, activists will say “pre-industrial.” But, why? ➌ What is the “correct” amount of bad weather? How many tropical cyclones, tornadoes, thunderstorms, hailstorms, droughts, floods, heatwaves, cold waves and wildfires should there be per year globally? Please provide exact numbers and then explain why. ➍ Why do you think temperature departures from the 1850 climatic baseline mean is the sole metric which determines human welfare? Why would the climate of the Little Ice Age be preferable than today's climate? What was better about the climate in 1850 than that of 2024? Is today's climate too dangerous? If so, why? Provide data and evidence to support your reasoning. ➎ What is the “correct” atmospheric carbon dioxide level? What dry-air volume or a range of atmospheric carbon dioxide concentrations would be optimal for plant growth? Show me data and explain why. ➏ The Inflation Reduction Act (IRA) was popularized as the biggest piece of climate legislation in history. But, since it was signed into law, climate activists say climate change has only gotten worse. Why? ➐ Trillions of taxpayer dollars have been spent on so-called “climate action” over the past 35-years. When will that give us that perfect climate, and when it does how will we know? What measure? ➑ If the U.S. spends hundreds of trillions of dollars to decarbonize our economy to achieve “net zero” by the year 2050, then how much will it reduce GMST by the year 2100, assuming the climate models are accurate? Please round your answer to the nearest tenth of a degree Celsius and show your math! ➒ If you can't provide me with an answer to question eight, then here's my follow-up: If you don't know how much net zero emissions in the U.S. would reduce GMST by 2100, are we supposed to just spend all that money and see what happens? ➊⓿ Why do efforts to mitigate exclusively center on reducing carbon emissions, and ignore more effective strategies such as building weather-resilient infrastructure and enforcing stricter zoning codes? Nobody has ever answered these questions, at least not in a clear and concise manner.

grasping at straws....no proof just assumptions without data

What about Coatesville's obs time in July of 1934 at 8am and 8pm?

Certainly possible but not proven by the written observation evidence we have....a non-issue

So, I went back and looked at the time of observation temps for July 1934 and only on 1 day the 8th during the entire month was their an issue. In fact in all other 30 days the high temp the following day was higher than the 4pm observation reset. There was no TOBs impacting either the 22nd or 23rd as the high temp on those days was higher than the 4pm reading the previous day. So overall TOBs as we can clearly see had a relatively minor impact on the overall Chester County average temps in July 1934

After a well below average temperature day to start July we should see a couple close to normal early July days....before the weather turns a bit unsettled as we head into the 4th holiday period. A lot of our records for today were set on a very hot day in 1901. Highs across the County were Coatesville 103 degrees / Kennett Square-Phoenixville and Westtown at 101 degrees and West Chester at 100 degrees. Other records for today across the County: Low temp 45 degrees at Devault (1988) / Rain 4.53" at Nottingham (2022)

Agreed! Actually the Warwick MADIS station sits at for the county a relative lower elevation at 407 ft ASL. But they are well positioned to take full advantage of radiational cooling nights that never happen in higher spots like KMQS and West Grove. A good example was this AM where they were the chilliest spot for the low at 53 degrees with KMQS at 61 degrees

Here in the Philly burbs of Chester County PA June 2023 was only good for the 15th warmest June since 1893. More interesting is 13 of the 20 (yellow highlights) warmest June's occurred prior to 1980. Back before our current warmer cycle....

We finished June across Chester County with the warmest average temp 72.6 since the 73.8 average temp in June 2010. The warmest spot was of course Phoenixville at 75.2 degrees and the coolest was the 70.6 degrees at Warwick Township. All stations (16) finished with an average temperature of 73 degrees or lower with the exceptions of Phoenixville and KOQN West Chester Airport (74.5). The wettest station during June was Nottingham with 6.89" of rain -the location with the least rain was KOQN with only 1.84" Our average temperature across the county through the 1st 6 months of the year 51.1 degrees is the warmest first half of the year since the 51.6 degree average back in 2012. Overall this was the 15th warmest June on record....following last year's 8th chilliest June of record.

Than we drop Phoenixville and it still makes no difference in the analysis!!
