This was my heaviest rainfall in an hour since moving up to CT. Picked up 3.18 yesterday in only one hour. The daily total in my area was 3.72.

Central PA Summer 2026 Discussion/Obs Thread
Mount Joy Snowman replied to Voyager's topic in Upstate New York/Pennsylvania
Low of 69 with a paltry .01” of rain. Just too much cloud debris around yesterday to ever really get things going. Good news is the upcoming stretch of weather is about as good as it gets for late July. Enjoy. -

Pretty wild how we have had elements of the summer 2011 weather pattern against the backdrop of such an extreme developing El Nino. -
2026-2027 Super El Nino

We’ve now passed 1997’s OHC record, we are over +2.6C The Peru weather service just updated, they are expecting “extraordinary” (aka super) El Niño costero (region 1+2) conditions, with SSTs greater than +3.5C to continue into 2027….. Region 3.4 continues shattering SST records -
Picked up 0.89” here, which isn’t as much as I thought. I was in the city last night and they definitely got more.

Chester County PA - Analytical Battle of Actual vs. Altered Climate Data
chubbs replied to ChescoWx's topic in Climate Change
Nope no dust bowl in Chester County, just Phoenixville with a bad shelter location. Philadelphia and West Chester don't agree at all with your plot. Not surprising since once again you are confounding station changes and weather. East Nantmeal and West Grove are a little different than the City of Coatesville or West Chester don't you think? -
Congrats north, south, east, and west of me. .60 here while just about everyone received 3-6". Ugh the boring drought continues in my area. I'm going to have to start chasing rain events. So bored. I can't wait until LES season lol

Chester County PA - Analytical Battle of Actual vs. Altered Climate Data
chubbs replied to ChescoWx's topic in Climate Change
Clear that you do not understand the science behind bias adjustments. Bias adjustments are not made in an ad hoc manner or to raise or lower the temperature of a station. Bias adjustments are only made to correct station changes. If the station observation time doesn't change, then no adjustment is needed. Adjustments are based solely on raw data. A station has to change with time in a manner that is different from all other stations that experience the same weather. The goal is to include weather and exclude station changes when calculating long-term climate trends. The only way to evaluate bias adjustments is to inspect raw station data at the time of the station change. Here's an example using the West Chester 1970 move. The old West Chester COOP shut down in December of 1969 and re-opened in May of 1970 at a new location. Subtracting Coatesville from West Chester isolates the relative temperature changes at the two stations at the time of the move. The raw data shows that the new West Chester site cooled by significantly relative to Coatesville after the move. That's all the proof needed to identify a major station change at either Coatesville or West Chester. We know from raw data from Phoenixville that West Chester is the guilty party. The Chesco raw data clearly shows that West Chester cooled significantly after its 1970 move. The NOAA bias adjustment is in complete agreement with the raw data from Coatesville and West Chester. That shouldn't be surprising. NCEI is using all the raw data that experiences the same weather as West Chester, hundreds of stations potentially. I've looked at multiple large station changes at the Chesco COOPs and NCEI nails every one. Note that NCEI is asking a similar question as your AI analysis. Does West Chester respond to local May 1970 weather in the same as the other regional stations? However the NCEI procedure is much more targeted than AI, is using more data, and it is using the right conceptual model. The temperatures at West Chester do not vary independently of the temperatures at Coatesville or other stations. This gives the NCEI analysis much more power. It can correctly flag the West Chester move as a major station change. While your AI analysis can not. The raw data is the final arbiter and in this case NCEI is clearly superior to AI. -

I am not versed in the exact physics of the processes, but I can say this. "Fat" CAPE on a sounding plot is not the same as "skinny" CAPE. "Fat" CAPE promotes more rapid updraft acceleration (image 1), and "skinny" CAPE promotes less rapid updraft acceleration (image 2). If you want svr wx, "fat" CAPE is more conducive to produce it. "Skinny" CAPE is better for heavy rainfall and flash flooding potential.

The Great Chuck Chodes wouldn't have screwed it up this bad. Speaking of the king, he had a term for this kind of storm behavior. I believe he called it circle jerking the Commonwealth, but I could be mistaken. -
