Wobbling a bit!! No drop yet but fingers crossed...cmon fan aspiration!!!

I'm betting on a 0.7 to 1.2 degree drop when the fan aspirator kicks on....

Charlie what you meant to say was Why? Because every single station in Chester County shown above and all of the other stations have had adjustments made to the raw actual data that only after that post observation alterations are made can we see any statistical warming at all. Charlie which of the stations Coatesville, Phoenixville, West Chester, Allentown, Quakertown, Reading etc. did NOT have chilling adjustments made to the 1920's thru 1950's with man made climate change adjustments to the raw data??

Always amazed at how much warmer you are than more southern places like here in Chester County. What is your elevation there again?

Today will be our last day with high temperatures near 80 degrees for about the 5 days. That is pretty close to the normal high for next week across the area. The good news is there is no sign of any 90-degree temperatures across Chester and SE Berks Counties till late June. Rain chances increase tomorrow and through the weekend but not a washout. The NWS has forecast of rain to be between a 0.25" to 0.50" by Monday morning. Generally showery weather looks likely to continue for Monday and Tuesday before we finally clear up and warm up to near 80 degrees again by mid-week.

No one in Chester County even close to that the last 2 days....86 was the highest. What is your elevation there Voyager? assuming a low valley locale??

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....

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
