ChescoWx

Again your issue remains cherry picking only certain stations. My Chester County data includes up to 18 stations (COOP/Airport/DEOS) during this 25 year period. The magnitude of heating is NOT at all the same as PHL....just the facts Charlie!

Going back how many years??

Then please show us any weather event that occurred that is unprecedented and has been proven to have occurred as a result of our current warmer cycle of our typical climate change?

Some overnight showers have ended but we could see a couple later this morning and again later in the day. We then still look to have a shot at our 2nd "heat wave" of the summer here in Chesco with Monday through Wednesday looking like most spots with the possible exception of the highest spots topping 90 all 3 days. The pattern change we have been talking about arrives with a cold front on Thursday. This will usher in almost an autumnal feel to next weekend with highs in the mid to upper 70's and cool 50's at night.

As always you deflect and distract from our actual data. You as always default to your standard answer about some speculative after the fact adjustments....I am presenting actual real data from stations over the last 25 years not back to your fictional post hoc adjustment periods....the actual real averages are clear that the real world stations that are the only data we have clearly show an increasing slope of variance between Chester County stations and PHL Airport....that is the facts!! You show nothing above to dispute these facts.

LOL!! Actually impervious to conspiracy climate theorist who support doom and gloom and for some reason try to convince folks there is actually something we can do to impact our climate. A great example of one of these conspiracy theorist is our old buddy Al Gore - he is my favorite prophet of climate doom and gloom! Here is Gore speaking at the WEF: "[Greenhouse gases are] now trapping as much extra heat as would be released by 600,000 Hiroshima-class atomic bombs exploding every single day." "That's what's boiling the oceans... and creating the droughts, and melting the ice, and raising the sea level, and causing these waves of climate refugees, predicted to reach one billion in this century." That is just pure loony tunes stuff!!! I wonder how many folks on this forum actually believe any of the above from our pal Al??

Fortunately we have actual factual raw data to show how PHL Airport is quite noticeably heating at a rate quite higher compared to Chesco during our current warmer climate cycle. The last 25 years as the UHI continues to worsen is the telltale sign based on the analysis. The differences between PHL and Chesco continue to steepen. If we break the average temperature change down to simple 5 year increments highlighting the growing gap between PHL and Chester County we can clearly see the worsening urban heat island that is PHL. From 2000-2004 +5.2% / 2005 - 2009 +5.5% / 2010-2014 +6.9% / 2015-2019 +7.1% / 2020-2024 +7.1% - can't be much clear than that! The gap continues to widen - I suspect with the PHL problems we may start seeing near double digit % gaps with the delta widening from where it is now in the +3.8 degree difference to somewhere near 4.5 degrees within the next decade or so!

Below is an analysis of excessive heat - represented by temperatures exceeding 100 degrees in Chester County PA by decade from the 1890's through today. There is a clear trend for less excessive heat days with 100-degree readings becoming a relatively rare event compared to the 1900's through the 1950's. On average Chester County PA is down to maybe 1 time per station per decade. The below shows the number of days, average days per station - this is included to take into account many less stations prior to the 1990's. Of interest is even though there are more current stations at similar elevations relatively close to those older historic stations excessive heat is just not like it was for our parents and grandparents.

Today will be several days cooler with high temperatures mostly in the mid to upper 80's. So far this year Chester County has experienced only one heat wave (at least 3 consecutive 90+ days) back on June 23rd through June 26th. We have what may be our last chance of a 2025 summer heatwave early this week as Monday through Wednesday may see temperatures at or near 90 degrees. We then turn much cooler with a pattern change to well below normal temperatures as we close out July and move into August. The best chances of rain look to be tonight and later Sunday.

Great quote from Professional MET Chris Martz "To think that we actually have the ability to significantly control the weather is an exercise for superstitious people. We are a fart in the wind in the grand scheme of things, and to spend all your life worried over things you have no control over is a waste of time." Is human induced climate change our biggest conspiracy theory out there??

Will be fun to see another climate doomer forecast fall by the boards.....

Below are the number of 90 plus days so far at the major climate/airport sites across the Northeast US - PHL 24 days. / ILG 15 days. /ACY 16 days. / ABE 8 days. / TTN 10 days. / RDG 17 days./ GED 20 days. / MPO 2 days. / EWR 24 days. / DCA 22 days./ BWI 17 days. / NYC Central Park 7 days. Now let us contrast that with the 90 plus days across the Chester County sites London Grove 3 / Devault 6 / Chester Springs 6 / West Bradford 6 / Kennett Square 6 / Warwick Twp. 4 / Nottingham 5 / Longwood Gardens 5 / KOQN Airport 7 / KMQS Airport 4 / West Grove 3 / East Nantmeal 3 /Avondale 2N with 4 days.

Avondale 2012 average temp = 54.4 / 2023 = 54.4 / 2024 = 54.6 - scary warming trend there!!

Or is it UHI at the Airport? 1940's vs today of the problem that is our PHL Heat Island.

The heat and humidity return today with many spots near or above 90 degrees. We cool down a notch over the weekend but with increasing shower chances by Saturday night into Sunday morning. Hot again early next week before a big cool down arrives by later next week.

Which of these things is not like the other??? Can we say UHI contamination??? Wonder why we only show PHL on the local news???

Several spots across the county have yet to exceed 90 degrees this month including East Nantmeal, Atglen, Avondale 2N and West Grove. While today we should stay in the mid to upper 80’s tomorrow many of these spots should see their first 90 plus day in over a month. The heat will back off a few degrees over the weekend with some storm chances before we heat up again to possibly more 90’s by Tuesday. The good news is a pattern change back again to cooler and low humidity weather looks likely a week from today and should last into the first week of August.
