Even vs. Morgantown a few hundred feet higher we see the same telltale pattern of chilling the past - altering those stations below what any actual station shows for the area.

Another near normal temperature day today with highs around 60 degrees before we see much warmer weather moving in tomorrow and lasting much of the upcoming work week. The warmest day looks to be Wednesday with highs in the middle 80's. We have a slight chance of some showers both tomorrow night and again on Wednesday night.

Today way back in 1894 Chester County shoveled out of the largest April snowstorm in County history with over a foot of snow across much of the county including 29.2" at the Coatesville 1SW NWS cooperative observer station. Nothing like that in our future this April as after near normal temperatures around 60 degrees both today and tomorrow we start a nice warmup peaking with high temperatures in the mid 80's both Wednesday and Thursday. Our best chances of showers arrive by the end of the upcoming work week.

Thank you! You finally admit you don't know which stations were used from the 1930's thru 1980's to make those chilling adjustments to the one specific station (Coatesville 1SW) for each of those adjustment years!! It only took several years LOL!!!

So show us the exactly which "other stations" you are referencing that were used for the calculation? You say Coatesville 1SW results/raw vs the NCEI adjusted figures above for Coatesville 1SW don't provide evidence about the adjustments. Agreed that is what I am looking for evidence and the underlying calculation based on the "other stations" you reference so we can tie down those annual adjustments from the raw to the adjusted/altered figures. Those adjustments above are unique to the Coatesville 1SW station so show us the reference stations used to make the call to adjust lower than Morgantown and in many cases lower than any reporting station at all in Chester County. You never show any of that data...you simply keep saying just believe that NCEI "could be right"

The fact you are on here indicates you have the same hobby or profession as I do! Plus tell me what you know about my life. family, economic position, happiness etc. - I bet you know nothing yet judge another person's existence as sad based on one's weather hobby/passion! I am pretty sure the sadest existence is one who criticizes another's existence or life without any deep knowledge of any aspects of that person's life. Be better!

Charlie again you are not following! If after the 1948 move it was colder than the City of Coatesville riddle me why they continued the same chilling adjustment to the newer chillier location? Not just for 1 year but for every year but 1 from 1948 through 1971. Even more bizarre can you explain why those NCEI number in 15 of the 20 years from 1952 thru 1971 were actually adjusted by NCEI to averages even lower than the high elevation station in Morgantown? Where is the control arm station that figures let's cool down the new chiller station location to even colder than a higher elevation further north station? There is absolutely zero support for these adjustments! 1948 51.2 50.0 (1.1) 1949 53.4 52.6 (0.8) 1950 51.1 50.8 (0.3) 1951 52.2 51.2 (1.0) 1952 52.4 51.6 (0.8) 1953 53.7 52.8 (1.0) 1954 52.3 51.8 (0.6) 1955 52.3 51.9 (0.5) 1956 51.3 49.6 (1.7) 1957 52.6 52.0 (0.6) 1958 50.2 50.2 0.0 1959 53.5 51.8 (1.8) 1960 51.7 51.2 (0.5) 1961 52.3 50.4 (1.9) 1962 51.0 49.8 (1.2) 1963 50.7 49.5 (1.2) 1964 51.8 49.8 (2.0) 1965 51.8 50.3 (1.5) 1966 51.4 50.3 (1.2) 1967 51.1 49.6 (1.5) 1968 51.9 50.8 (1.1) 1969 51.5 50.2 (1.3) 1970 51.5 49.8 (1.7) 1971 51.7 50.7 (1.0)

Today will be our first above normal temperature day since Easter Sunday. We should see some sun later today with temperatures well into the 60's. We chill back to normal temperatures over the weekend with highs in the low 60's before a big warmup next week. The warmest day here in Chester County looks to be Wednesday with highs in the low to mid 80's (1st 90+ possible near the Philly heat island area) Temperatures start to cool a bit later next week. Sadly, no rain in the forecast at all!

Easily disproved by the actual NCEI adjustments made - see below. Based on what you show above there was no need for cooling from 1941-1946 yet look at what NCEI did...actual raw on left adjustment on left. 47 1940 49.1 47.6 (1.5) 48 1941 53.8 51.6 (2.2) 49 1942 53.6 51.3 (2.3) 50 1943 53.4 50.4 (3.0) 51 1944 53.8 51.2 (2.7) 52 1945 53.6 50.8 (2.8) 53 1946 53.5 51.3 (2.2)

On X today ABC Chief Meteorologist Ginger Zee answered a message I sent to her regarding the controversial NCEI temperature adjustments that have been made to the actual historical raw NWS Cooperative Data. Below is her response and a link with her "deep dive" report on the controversy. To be honest her report for the most part simply repeated the standard response saying "the science supports it" which is what you will always hear. For many folks with that answer from a professional meteorologist, they will simply nod their heads and say well if the science says it must be so. This in most cases will often stop any further questioning of the data. To Ginger's credit she agrees with my long-held stance in the video that science should always be questioned and evaluated. I certainly have questions and have to date not found any solid support for the consistent 2-to-3-degree chilling of the old data for every single year from 1895 through 2000. So, I will continue to question these adjustments. Science is always about questioning data not blindly following! https://t.co/e5CFYdO803 Below is my response to Ginger with the data to try and support any adjustments to the raw data. Thanks Ginger but you didn't get into the deeper detail as to the explanation for the changes made to not only the ASOS sites at Airports you mentioned but to the NWS Cooperative Observer Data. A case in point is the long running Coatesville 1SW NWS Cooperative Station data for the philly burbs of Chester County PA with data from 1894 through 1983. There are many reasons given for these post observation ad hoc adjustments. The most common are station moves and time of observation adjustments. Below shows that for this station NCEI chilled 86 of the 89 years between 1894 through 1982. Below are the station moves grouped by year. These were all within a couple miles in each case with annual clear consistent cooling adjustments applied to the raw data. The time of observation adjustment also is not relevant in this case as only for 11 years (1910-21) was the daily observation taken only in the evening. So how and why exactly was this particular station chilled so consistently across 97% of all years?

Another widespread freeze this morning across the area with our lowest Chesco climate station the 24.7 at the Warwick DEOS. We remain well below normal today with highs in the middle 50’s, but a nice warming trend kicks in starting tomorrow and we get very warm with low 80's possible by next Tuesday and Wednesday! We could use a little rain but nothing in sight over the next week.
