Digging into the past climate adjustments to Central PA - the same consistent chilling adjustments to the past that produce a warming trend line after these adjustments as we see across most of the U.S. to the historical data NWS data set. Green color is actual raw data....blue is after NOAA/NCEI makes their tweaks. If not for these chilling adjustments to the blue revised average annual temperatures - not much warming if any.

If we could only find some actual real station data to use from someplace close to an actual NWS station that helps support these 1 to 4 degree annual average temp adjustments to these many NWS Cooperative Observer stations....we of course cannot find any of those - hence our problem! But if you have those please produce them as Charlie certainly never can seem to come up with any actual real stations with data....

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??

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.

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.

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.
