A bit warmer today before our first 70 degree plus day of the year tomorrow across many of the higher spots across the area. In fact, tomorrow will be our warmest day here in East Nantmeal since the 73-degree reading back on November 7th. Still mild through Monday before a turn to cooler on Tuesday. Some showers are possible this evening, but a better chance of rain arrives Sunday night into Monday night. The Phillies home opener on Monday may be delayed till Tuesday.

Happy Phillies Opening Day to all who celebrate! Go Phillies!! Today will be our 2nd straight below normal temperature day. Through yesterday we have seen only 5 below normal days this month. We start a big warmup tomorrow and through Monday before we turn sharply colder and fall back below normal by next Tuesday. Slight rain chances on Friday night but a better chance by Sunday night through Monday.

We also saw a few flakes here along the soaring peaks of The Welsh Mountain anticline here in Chester County....

I actually went back and looked at the NCEI adjustments specifically for the West Chester Station (there are some gaps on both the actual and adjusted figures for quite a few years especially in 1910's / 1970's and 1990's) - but from what we have they chilled every single year from 1880 thru 1969...then began additional cooling adjustments from 1979-83 of 0.6 degrees. NCEI then decided to alter the actual data with some of the largest cooling adjustments on record from 1987 thru 1990 of between 3 and 4 degrees each year. To cap it all off they then began to consistently warm the final 10 years of actual data with a steady 0.3 degree warming adjustment made to each of the years between 2007-2017.

Sorry Charlie - the DEOS data is actually runs operationally by NCEP and all of this data has been QC'd and added to NOAA's data archive and is being used by the NCDC. The data above was in reality run without "my house". It is only NWS QC data. So which of my data has not been certified by the NWS??

LOL! Charlie knows my data is available and not hidden. Anyone can obtain and analyze the data. It is all public data. The data is the data! My methods are fully and completely disclosed. My method is to only include the actual certified NWS Cooperative Data....nothing more! No data manipulation so no methods - just raw and the facts!!

LOL!!! You will note in the above I asked Charlie to take it to the Chesco thread where we are continuing the debate....

@TheClimateChanger in case you forgot - below is the available on the internet raw data and the analysis comparing the Actual Raw data vs the altered NCEI Data for Chester County PA. This clearly shows Chesco has not warmed 2 degrees (see orange actual raw temps) according to the unaltered data. However, you can clearly see in the blue line the altered post hoc data in blue that does show that warming that can only be accomplished by recasting the actual data and ignoring all of the actual raw data in Chester County.

Thanks @TheClimateChangerExcellent!! Likely but.....drum roll please "we can’t definitively say Chester County hasn’t warmed at all. " Fake news if it was Grok to " @ChescoWx’s refusal to share raw data or engage peer review undermines their case. Extraordinary claims need extraordinary evidence, and they’re light on the latter" I have often shared my raw data file plus it is all available via the internet. It is available upon request to anyone. Let me know if you want it?

Grok even mentions me! It cannot confirm!!! "Without specific data for Chester County, PA, from NCEI’s raw versus adjusted records, I can’t confirm the exact nature or extent of changes for that location. However, local weather enthusiasts, like those at chescowx.com, have noted that NOAA/NCEI adjustments have historically "chilled" Chester County data from 1893 to 2005 and "warmed" more recent years.

Now you jump to another time period....let's stay focused on the period in question (1927-1947). Show us some actual data for the period we are looking at above that validate NOAA/NCEI adjusting all temperatures lower than any thermometer anywhere in the county recorded during those 21 years in question.

So you are admitting there is no actual annual average thermometer readings that you can show us in the entire county for that period that support the cooler altered NOAA/NCEI data for even one of those 21 years of data across all of those stations?? Hello McFly......

Chillier than normal for late March both today and tomorrow with highs today in the upper 40's. A below freezing night on tap tonight for most of the area. We start a nice warming trend on Friday through Monday before we turn colder than normal again by Tuesday. A slight chance of rain late Friday night with better chances by Sunday night into Monday.
