Let's add Quakertown to the chilled man made adjustments to past history to show a warming trend.

Only our man Charlie is fooled as we just can't seem to find any warming at any long term station data unless we add some good old post hoc cooling to all stations (see above for all the man made climate changes to the data) so far we have included Allentown, Coatesville, Phoenixville - all with the needed past man made cooling adjustments to show a warming trend. Now, Let's add some more - see below that even at Reading they needed to chill all the old data for 100 years to finally produce some warming. All have the same tell tale signatures - the need for historical chilling of the past to try to show warming in the present! Are there any stations around that man did not need to chill (I mean adjust) to show some current warming??

Again my station is not part of the data set for Chester County PA!

We strive for accuracy!!!

NWS (National Weather Service) siting standards are intended to be consistent with the surrounding area, particularly when it comes to Cooperative Observer Program (Coop) stations. This means the site should be representative of the weather conditions experienced in that specific location. Siting guidelines aim to ensure accurate and representative weather data collection. Not that it matters as the data excludes my backyard for climate comparisons. But,, as you can tell with the satellite photo I am consistent with the surrounding terrain. Plenty of trees but not many houses.

LOL!!!You as usual are not following forky....my backyard data has zero to do with the data in this discussion....

Thank God I pay for the most expensive station that has fan aspiration to correct for solar errors of surrounding stations!!

A Vantage Pro 2 (VP2) weather station with a fan-aspirated radiation shield significantly improves temperature accuracy by minimizing the impact of solar radiation and other radiated heat sources on the temperature sensor. The fan draws air through the sensor chamber, reducing temperature errors and providing more reliable readings, especially in areas with low air flow. Accuracy improvement: This method improves accuracy by up to 1.5°C (2.7°F) in areas with low airflow, according to Instrument Ch Here's a more detailed explanation: How it works: The fan-aspirated radiation shield uses a fan to continuously draw air through the sensor chamber, preventing the temperature sensor from being heated by direct sunlight or reflected heat. Accuracy improvement: This method improves accuracy by up to 1.5°C (2.7°F) in areas with low airflow, according to Instrument Choice. Power source: The fan can be solar-powered or run on batteries, depending on the specific model. Benefits: Using a fan-aspirated shield ensures more reliable temperature measurements, especially in sunny locations or areas with limited natural ventilation.

maybe that is when the fan aspirated fan kicks in....improves reliability with the VP2 Pro Model

Another one - more man made climate changes at Allentown Airport - again chill the past and warm the present!! Very conistent man made climate changes across the area!!

and what about those days it does not happen???

nope - see above that is the actual station data

No drop yesterday.....

Show me the statistical data and reason and reference any station relatively nearby showed the need for a 3 to 4 degree adjustment during those years...

Certainly not 3 or 4 degree annual adjustments for years in a row are not supported by any data at all!

Fake news as usual - High temp times so far this month 1st - 322p / 2nd 441p/ 3rd 434pm / 4th 2:17pm...be better my man!!

Charlie so why again are all stations you mentioned Coatesville, West Chester and Phoenixville all clearly chilling the past and warming the current. See the raw vs adjusted for each below.

That is simpy an equal chance outlook... far from a forecast. The extended Euro and GFS models paint a normal to below month - not saying there won't be a warmer week in the mix.

You clearly keep making up arbitrary data. Let's dig into another station you mention above - West Chester PA. So why was West Chester also chilled by between 1.0 and 3.7 degrees each and every year for the 103 years between 1880 and 1982? Chilling the past remains the only clear man made climate changes to our data.

The warmest temperature across the county yesterday was, of course, at the Brandywine Airport in West Chester at 86.0 degrees. Most spots saw temperatures between 81 and 84 yesterday. Today should be a degree or two warmer and will be the warmest day for a while. The pattern turns a bit unsettled later tomorrow and through the weekend. Not a washout at all but some showers are most likely on Saturday. Shower chances appear to increase again by next Tuesday. Our relatively wet pattern looks to continue with no foreseeable heat in our future. In fact most models show near normal to slightly below average temperatures through the 4th of July.

Your problem is you have zero proof any of those moves required a 2 to 4 degree temperature adjustment which is what took place. As a simple example (small sample size but enough to be clearly directional) I have analyzed the difference between the relatively rural Coatesville 2W at 660 ft ASL vs Thorndale 290 feet above sea level and in the middle of a sprawling development but only a few nautical miles apart. Even a move from the relatively rural Coatesville 2W to an suburban sprawl development at almost 400 ft asl lower does not result in anywhere close to the magnitude of changes the NCEI tries to apply.

A nice couple of days on tap across the area with highs reaching up into the low 80's today and the mid 80's tomorrow. Tomorrow should be the warmest day of the week before we cool back to near normal with shower chances increasing by Friday night into Saturday.
