Today should be our last 90-degree day for at least the next 10 or so days. We will see rain chances ramping up tomorrow afternoon into the evening with a cold front. We could see at least an inch of rain in many spots across the area with showers lasting until Friday. On Friday night we see some autumn like weather arrive for the weekend. Highs mostly in the 70's with lows in the 50's. Below normal temperatures look to continue through much of next week.

Looks hot to me! Even Atglen has almost eclipsed 90....just a tad short at 89.9 - West Grove also so close at 89.7 "only" 88.5 so far in EN but we still have some time.....

Again the detail behind the overall calculation that supports that PHL Airport has over the last 25 years been heating more quickly than Chester County thanks to UHI. I don't think this is a surprise to anyone is it?

Below with the supporting calculations are Phoenixville longest complete data vs. PHL over the last 25 years. The 2 stations are clearly not warming at the same rate....but the trending increasing differences between the 2 stations and Chester County as a whole is due to UHI at the airport.

This is pretty straight forward. I am simply plotting the degree of warming delta for each year at PHL vs each and every station in Chester County. They are not warming at the same rate as PHL. The above analysis across all Chester County stations quite clearly illustrates that Chester County individual stations along with the overall average for Chester County are not warming at the same pace as PHL that is due to the UHI problems at PHL.

PHL vs Longwood Gardens??? you guessed it - are any stations in Chester County warming as fast as our UHI contaminated PHL Airport?

How about that trained spotter station data from East Nantmeal vs PHL - yep you guessed it warming faster at PHL

How about our own little warm spot....Phoenixville vs PHL....again warming faster of course at the PHL UHI problem

Let's look at some individual stations - how about our climate reference network? Avondale 2N vs PHL

Again easy to fact check with the actual data and all stations not cherry picking a few included. To say CHESCO average temps are rising as the same rate as PHL if just false. Trend line paints the real story.

Not politics as both parties have cost our nation and it's taxpayers way too much for programs and studies that will not reduce or increase our temps by even 0.5 degrees.

As I mentioned yesterday some of our higher spots across the County had the potential not to reach 90 degrees on Monday and indeed 7 of the stations failed to reach there. So for those spots they will not "enjoy" their 2nd "heat wave" of the summer. For everybody else today will be day 2 and tomorrow day 3 but the final day of the "heat wave". We could see some heavy rain by later Thursday with a strong cold frontal passage. This will usher in well below normal temperatures for the weekend with an almost autumnal feeling as highs are in the 70's and nights in the 50's.

Charlie the below should better illustrate the point I am making above. There is a clear growing gap between PHL and Chesco. Can't be much clearer correct?

Look back in this thread I posted the chart. Just go out and add the DEOS data over the last 25 years - remove Spring City data before 2024 and voila you have the data. I even highlighted the growing % differences between PHL and CC - not sure how much clearer it can be.

Phoenixville PA- 1934 recorded 103 degrees on the 29th and 30th of June.....it has all happened before of course!

Most spots will see the start of Chester County’s 2nd “heat wave” of the summer season. Today through Wednesday should see highs topping out in the low 90’s each day. Today could be the exception across the higher ridge locales with highs a degree or two short of 90. A strong cold front will start to cross the area by later Wednesday night with shower and t-storm chances increasing and signal a nice change to below normal temperatures for next weekend. Below normal temperatures look likely for at least the first week of August.

Again no historical evidence of what happened in the Adirondacks in 1450 during those 4 straight warm decades where the average temperature in the Adirondacks increased from 50 degrees during the decade of the 1410's to 55 degrees during the 1450's etc. Of course we don't have that actual specific data - hence the problem! Clearly where we differ is you thinking any of the above current climate change during this warming cycle is in any way scary, dangerous or puts our planet in peril. My clear view based on the data is there is nothing to be afraid of here. Plus there is absolutely nothing that has been proven that has ever shown in our history right up till today that man can do anything at all to impact the current warming cycle or oh yeah that next cooling cycle that could be right around the corner. The earth and humans as always will easily adapt no matter what mother nature throws our way. Climate change no matter the warming or cooling is far from anything any human should rate in their top 100 concerns during their lifetime. Facts over feelings folks!!

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?
