Same relative minor warming curve as expected!

For sure it should show the same relative warming curve that has been occurring during these years....

It is for personal sites also - below is my station performance over the last 28 days....green check means good siting and readings...

I thought it would be of interest to do some deep analysis into my own weather station data that has been operational in East Nantmeal since November 2003 vs. The only NOAA Climate Reference Network (CRN) station here in Chester County which is the PA Avondale 2N station. These CRN stations are a highly specialized weather station designed to provide long-term, high-quality measurements of climate variables like temperature and precipitation. In essence, CRN stations serve as a high-precision benchmark for monitoring the nation's climate, ensuring the availability of reliable data for understanding and addressing climate change. I ran an analysis of East Nantmeal vs. Avondale 2N over the last 18 years that we have both been recording the weather. I have to say I am pretty pleased to see that our observations could not get much closer than this – exactly the same average temperature over 18 years of data!! I have only used a Davis Vantage Pro 2 station with the fan aspirated shield over the entire 22 years I have been recording data.

During the last month the radiation shield problem at that Coatesville station was enhanced by that heat wave....stations with strong shields like the VP 2 Pro that I have always used will be superior during heat waves. Below is the 28 day comparisons including the heat wave.

Last 26 weeks at East Nantmeal - good QC of course

Now my station over the same period....

That station is a personal weather station that uses The Acu-rite 5 in 1 personal station. A low cost model without fan aspiration - and the QC check failed of course over the last 2 weeks with that heat wave. It is recommend that station get a radiation shield to correct it's errors!! See the analysis below.

The warm and muggies continues for the foreseeable future. Today should be the warmest day over the next week with lower elevations getting close to 90 degrees. A heat watch and a flood watch have been issued. Rain chances increases again toward evening with the NWS forecasting between 0.75" to 1.25". Tomorrow might be relatively the driest day with Thursday looking like the wettest after this evening. Temperature wise it looks near normal with highs in the mid-80's but with nights a few degrees above normal in the upper 60's.

LOL!!!! The truth is out there Charlie! It is so much fun peeling back the onion skin on these kind of data puzzles! Where and how did these alternate facts get added???? The raw facts as always will win out - stay tuned! The amount of interest in this across the media platforms is amazing!

Of course in reality IEM serves as a data provider to the NWS and others I am looking to see if some of this data is incorporated into how NCEI arrives at their adjusted data....to tweak the actual real climate data.

Don, it's the doomsday views and failed forecasts (Hello Al Gore) attribution of what is of course just weather that will continue to doom the climate alarmist agenda....all weather events that are occurring now have happened before. Until that changes there is little scientific reality ground to stand on!

LOL!! your "science" moved on the rest of us rooted in reality and actual data are not fooled.....

Looks like another temperature Ghost Station with the Coatesville 1E precipitation only station....generating high and low daily temps without the observer doing so! Thought ghost data ended back in 2014....looks like it continued right through the end of 2022....

https://mesonet.agron.iastate.edu/request/coop/fe.phtml?network=PACLIMATE One example of many below....this is a precipitation only station - so those Tmax and Tmins are ghosted estimated data......

So I have finally completed the analysis of the Ghost Data stations and compared their inputs vs. the actual averages across the County. NOAA has employed techniques like interpolation to estimate temperatures in what they normally would say are data-sparse regions and in other cases this data may be resampled from another grid. Of note there are seven (7) ghost stations employed across Chester County PA with this estimated temperature data in the period of record from 1895 through 2013. All of these were during the ghost years reporting only precipitation data. Some eventually did begin actual temperature reporting after the ghost years. The Ghost Stations and years of estimated data are Phoenixville (1895-1914) / West Grove (1928-1962) / Coatesville (1948-1955) / Glenmoore (1957-2005) / Honey Brook (1957-2013) / West Chester 2W (1979-1981) and Devault (1988-2004). Overall there are 189 years of ghosted data used to "fill in data gaps". Of note this ghost data was warmer than the actual county records in 101 of the 106 years of ghosted data between 1895 and the "shuttering "of the last remaining ghost station at Honey Brook in 2013.. The largest warming adjustments were unsurprisingly made during the coldest decades of the 1960's and 1970's. Below is an analysis of the impact on average temperature trend lines between the actual raw data and ghost data in the years these adjustments were applied. Some more analysis on this data will follow.

The NWS has issued a flood watch for today and a heat advisory for tomorrow. There is a growing threat of flash flooding for some spots across the area. Forecast models have been a bit inconsistent on exactly where these will be so will be keeping an eye on those radars. We should remain warm and humid all week with the hottest day being tomorrow where some lower elevation spots may touch the low 90's. Ridge locations will likely fall just short of 90. We turn a bit cooler but still humid by the end of the week with temperatures a few degrees below normal during the afternoons but a few degrees above normal at night.

We are not alone in altered man made climate change

After the last 2 days with below normal temperatures we will see increasingly warm and humid weather today and through much of next week. Today looks like it is the only day that should stay dry. Rain chances will continue all week. The best chances of heavy rain look to be Monday into the evening. Wednesday looks to be the relatively driest day. Today should be our warmest day of the week with lower elevation spots across the county possibly touching 90 degrees while ridge locales will likely only reach the upper 80's.
