ChescoWx

Some 50's for lows again in the lower spots of the County this AM. Another sunny day today with some increasing humidity. Shower chances start to increase on Tuesday. Thursday looks like the warmest day of the week with most spots except for the higher locales could reach 90 degrees. Chester County records for today: High 101 degrees at Coatesville (1941) / Low 47 degrees at Phoenixville (1977) / Rain 4.19" at Devault (1969)

As we have just passed Christmas in July....and for the many of you on Team Snow - why not list out all of the greatest annual snow seasons (October-April) on record across the Chester County NWS cooperative and trained spotter observation sites.

Great mid summer weekend underway... some valley locales in Chesco again hit the 50's for low temps this morning. Sunny weather through Monday before increasing chances of some showers by Tuesday which last through the rest of the week. While there will be rain chances certainly no wash outs and some sun each day. Chester County records for today: High 100 degrees at Phoenixville (1944) / Low 46 degrees at Phoenixville (1977) / Rain 3.19" at Morgantown/Elverson (1958)

Snowfall For Chester County PA 1888 to Present by Decade

Some spots touched the 50's this morning across the County. Beautiful weather with low humidity continues through at least Monday before our next chance of showers. Chester County records for today: High 100 degrees at Phoenixville (1930) / Low 42 degrees at Morgantown/Elverson (1976) / Rain 3.28" at Spring City (2023)

Climate alarmists claim we are observing more record high temperatures than ever before. However, the below analysis of 590 USHCN stations with at least 100-years of daily observations reveals that 60% of daily record high temperatures were in reality set before 1960. Of the top 20 years, only two have occurred in the last 65 years!. The top 20 years with the most daily record highs in the U.S.: 1936, 1934, 1931, 1939, 1925, 1930, 1933, 1911, 1953, 2012, 1921, 1954, 1927, 1910, 1918, 1950, 1990, 1947, 1938 and 1952. Just like at the local Chester County locations the hottest years were back in the 1930's....

Is this the source of the 97% of scientists agree myth?

One more cloudy day today before a great stretch of weather through at least Monday. Cooler starting tonight with some spots in Chester County possibly touching the 50's tonight and tomorrow night. Chester County records for today: High 100 degrees at Phoenixville (1930) / Low 47 degrees at Coatesville (1976) / Rain 5.17" at Nottingham (2021)

Thanks Kevin! It really has been hit and miss. I suspect you are correct some tropical storm will come up the coast and interact with a cold front and bam - 4 to 6" of rain for all!! let's hope we see some more rain over the next days further south and east! Good luck!

We picked up some light rain overnight in some spots with 0.03" in East Nantmeal. We are now almost 4 inches above normal rainfall now this year following our fairly wet stretch of weather this month. Shower chances continue today and especially tomorrow into Thursday evening before we clear up and have a great stretch of dry weather through at least next Tuesday. Chester County records for today: High 100 degrees at West Chester (2011) / Low 48 degrees at Coatesville (1985) / Rain 2.95" at Elverson/Morgantown (1969)

Now this is funny and true....how many of these comments are thrown at climate realists by climate alarmists??

For folks clamoring for more analysis and debate over real vs altered climate data come on over to the new thread under climate change!

Below is a great illustration of how the post observation NOAA/NCEI adjustments are skewing the analysis. They are continuing to warm even the current decade - following the chilling adjustments made to the hottest summer decades back in the 1930's thru 1950's. If you believe the red NCEI trends we are warming pretty quickly....if the actual raw blue data is viewed....almost flat! No summer warming here in Chester County PA....

The only "mischief" is the baseless bias adjustments for TOBS and other estimated post hoc bias adjustments! We have seen these baseless tweaks applied even for places like Coatesville with no such TOBS bias. As always the actual real data shows the truth there is of course no climate emergency in any of the actual real world analysis....heck there is not even a crisis!! Only hand waving fear mongering for clear simple cyclical gentle climate change Hey Charlie - where is that reverse heat island adjustments you mention above for Coatesville and West Chester?? We only see traditional heat island cooling adjustments no reverse UHI warming adjustments???

Some beneficial rains overnight across all of Chester County amounts ranged between 0.23" at Nottingham to as much as 0.84" over in Atglen. Today should be drier and maybe even some sun breaks. Rain chances increase again tonight through Thursday before we dry out for what looks like a great weekend! Daily records for today: High 104 degrees at West Chester (2011) / Low 47 degrees in Phoenixville (1947) / Rain 4.93" at Phoenixville (1927)

Below a chart and thoughts from @ChrisMartzWX He looks at the entire US focused on the same topic I have been analyzing for Chester County PA - actual vs. adjusted data. "The actual thermometer data indicate that there has been little warming in the CONUS since 1895. Top 10 warmest years by raw data 1. 2012 2. 1921 3. 1931 4. 1934 5. 1998 6. 2016 7. 1953 8. 1938 9. 1939 10. 2015. "Pretty much all of the climate warming results from significant adjustments, to the data, most of which are due to the supposed “Time of Observation Bias” (TOBS). Essentially, government scientists think that hot days were double counted in the past because COOP station observers were too stupid to reset their min / max thermometers before they went to bed. If that were actually the case, it’d be a problem, but it would’ve been obvious right away to any station observer how these thermometers worked in a few days’ of using them. TOBS adjustments are based on assumptions that don’t have any basis in reality. That’s why the adjusted temperature data shouldn’t be used. I’m all for quality control, but the way in which thermometer data has been handled by bureaucrats is abhorrent."

The new home of all things concerning real vs.altered data....

Well i did finally find the ghost station data thanks to Meteorologist John Shewchuk and his site below - which according to John has now identified over 100 zombie or ghost stations https://noaacrappy.github.io/zombie-map/ It appears that some of these NCEI reported sites https://www.ncei.noaa.gov/pub/data/ushcn/v2.5/ are now ghosting or estimating data into retired stations that no longer report. In fact it seems we have an actual ghost station site right here in Chester County!! The old NWS COOP station West Chester 2 NW 369464 appears to have continued to report estimated monthly data for the last 7 years since the station was officially closed in 2017. Below is the latest average high temperature file today from NCEI for the West Chester Station. It lists the average high temps for every month since the 1880's. The highlights are when the estimates began following the station closing in 2017. So it looks like the latest reported Ghost West Chester Station 2NW had a reported average high last month of 30.36C or 86.6F. A quick review of the actual average across the county shows it was 83.7 degrees across 16 stations. The reality is only 1 of the 16 stations were anywhere close to 86.6 with 15 of the 16 were no closer than 1.5 to as much as 3 degrees cooler. Of interest that 1 station was you guessed it Phoenixville with that exact 86.6 average high temperature for June. So no doubt this has been discussed before but why do they use old closed stations? How are these estimates calculated? How are they used?
