Coatesville 1SW has a strong cooling trend in the raw data, as you observed. However, there are multiple breakpoints. Adjusting for those breakpoints brings Coatesville's trend in line with regional trends. From Berkeley Earth:

It's official. Chief meteorologist Cecily Tynan to retire after more than 30 years with Action News Her last broadcast will be on Monday, Aug. 31. https://6abc.com/post/cecily-tynan-retirement-announcement-6abc-action-news-wpvi/19562769/ Birds will be in mourning !

So let's look at a single station with long term data 1894-1982 Coatesville 1SW. I performed an analysis of that station to see if TOB bias was part of the adjustment for 77 of 78 years of cooling data that we have documented many times before from the raw actual data. I evaluated all of the changes in observation times for the entire period of record. Of note from 1946-1982 the station observed a consistent 8am reading whhich sits close to the −0.15°C (cool bias) end of the curve, meaning the TOBS-correct move would be to add temperature back (a small positive adjustment) — yet the actual 1946-82 adjustment stayed negative on average (−0.83°F). That's a clear red flag in the NCEI adjustments as TOBS alone would predict the sign should have flipped positive after 1946, and it didn't. So without TOBS alone there remains a clear and significant leftover unexplained cooling of roughly -1.1 to -1.8°F in every single period — evening, dual, and morning alike. That's the thing that needs a separate explanation, since TOBS alone doesn't account for it. So we have seen @chubbsoften say that station movements tied to Coatesville's industrial history and station moves impacted the data and made it critical to chill the old data. The problem that NCEI and Charlie has is that in reality Coatesville was home to Lukens Steel — a continuously operating steel mill since 1810, one of the largest specialty steel producers in the country, still headquartered there through 1982 and beyond this is a station within a mile of significant industrial activity! This of course is a textbook candidate for a persistent local warm bias — waste heat, paved/industrial surfaces, altered local airflow. But here's the problem for NCEI and Charlie to address - this doesn't match the data adjustments made by NCEI. The facts are that Lukens was arguably at its industrial peak in the postwar decades (1946–82) — yet that's exactly the period where the adjustment (and the residual) is smallest, not largest. If growing industrial heat were the main driver, the bias should have gotten worse over the 20th century, not better. So it is not TOB adjustments and clearly not site moves behind these adjustments so what say you Charlie?

That is likely because normal people don't speak with you..

What a day! Got about 1” in last nights rains, couple that with the day before’s 1.5”. Probably won’t do much for drought as it came too fast to soak in and most ended up in storm drains.

I bought a 2018 Accord from Lake Norman Genesis. (I would highly recommend them - great service, no pressure, let me drive it to Hickory so my mechanic could give it a look over.) I had a 2014 Accord. Wanted to upgrade a few years, and the older model became my youngest son’s first car. So, we both got new (to us) cars today!

what is so bad about seeing the euro after a restful night's sleep

As a utility worker i prefer Spring & Autumn over peak of winter and summer. Minus the storms in each though those are always awesome!

4.26” and still lightly raining. It won’t break the drought but it’ll damn sure make a dent.

What’d you pull the trigger on? There are some insane deals to be had right now.

Getting smoked now in Western McDowell. Will check the gage when I get home

Perfect setup with a dying tropical system and a stalled boundary. Looks like I picked up over 2 inches since 7 PM last night. I'll dump my rain gauge at 7 for a good reading.

It’s coming

3.83 and still raining here. Wow! Been back and forth to Huntersville a few times from Hickory today (buying a car), and there have been several torrential downpours. Crazy stuff!

That sucks! Good luck.

It can easily get over 100° in August I'm not sure what folks are talking about.

Trying to drive home

My Ambient is showing a rate of 4.16/hr. I am over 2 inches. Still pouring.

I removed Phoenixville and no statistical change to the raw data at all!!

nice thing with August and September is you can get stretches of fantastic weather, whether you like dews or coc - which is hella rare in February and March lol

Most Senators were alive during the 1974 year-round DST disaster that was thus quickly reversed. And can you imagine not getting the Euro til 2AM during the crucial winter season?

Flash flooding in Asheville

No wonder your reindeer can fly. As always …..

Damn, DEN is at .70" for the month. .92" in my backyard.
