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.

Some of the higher spots in the County like West Grove and East Nantmeal Township had highs remaining in the upper 70’s – most other spots hit the low 80’s. Plenty of cool and comfortable 50’s overnight with Warwick Township being the coolest spot with a low down to 55.3 degrees. Another beautiful couple of days producing temperatures warming to the mid 80’s today and maybe some upper 80’s tomorrow especially across valley locations. Rain chances increase by Monday night with the best chance by Tuesday.

Happy 4th again! Below is an analysis of our climate here in Chester County for Independence Day. As you can see overall in our 132 years of weather records back to 1893 we have seen an overall slight cooling of our high temperatures and a slight warming of our low temperatures. Not surprisingly our average temperatures on the 4th of July have remained mighty constant with no warming or cooling on average over the last 13 decades of weather observations.

Happy 4th of July to all of you! It should be an outstanding day for all of your outdoor activities with family and friends. Several of our colder spots had low temperatures this morning in the pleasant 50's. Tonight we should see even more spots reaching the 50's for lows by morning. Today we will see much of the day with temperatures in the upper 70's to low 80's - this is a couple of degrees below normal for the 4th of July. We start a slow warming trend tomorrow with our warmest day looking to be Monday with highs into the upper 80's. Still no 90 plus days in our future...in fact in looking at some of the longer-range models we might not see such a day through at least July 20th! The weather gets a bit unsettled with some shower chances almost each day of the new week - although no wash outs!

It's all ghosted fake data - no doubt that adjusted data is exacty what they use on CinCin TV networks to show their man made "warming" climate

The Queen City in Ohio joins the altered past climate group.....there really is a pattern here!

Where's the chilling for the recent years ongoing UHI problems at PHL???

Who can spot that same chilling of the past data in the SE Pittsburgh Burbs?? Do we see a pattern chill the past!!

Who can spot the UHI chilling adjustments done to the PHL Airport data?? Hmmm I guess there is no UHI amidst the runways and jet exhaust....

I've matured and removed the word from my vocabulary.....LOL!!

Pittsburgh like so many others spots including Chester County...let's just cool those pesky 1930's and 1940's ...it always gives us the answers we want....

@TheClimateChangerlet me help you our with a broader view of the entire USA.....say hey to the 1930's!
