Well above normal temperatures continue through Saturday before we see another pattern change to normal to below average temperatures lasting through much of the rest of the month. The warmest day looks like Wednesday with highs in the mid to upper 80's. Shower chances increase Friday night and especially Saturday night into Sunday with the cold front. Temperatures by next Monday may struggle to escape the mid-50's.

"That is a clear sign of a major station change, probably at Morgantown." That would be incorrect Charlie no station changes took place at all during the period that temperatures were reported by the NWS Coop observer. There were some moves after those temperature obs ended and they moved to just precip and snow obs.

We start our major warm up today with temperatures reaching well into the 70's. We warm into the 80's on Tuesday with our warmest days both Wednesday and Thursday. While places along the I95 corridor could see record highs in the 90's it looks like we should stay in the middle 80's here in Chester County. Our Chester County record high for Wednesday is 89 degrees set in Phoenixville way back in 1941. Thursday's record high is 92 degrees set at multiple county stations back in 1896 and 2002. We have a slight chance of showers this afternoon and again on Wednesday night, but our best chance of any showers looks to arrive on Saturday night.

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!
