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.

We will adapt as we always have whether we cool or warm.....the bottom line is there is of course no climate crisis!

Today will be another below normal temperature day across the area before we start a warming trend to close out the work week. The hottest day will be Friday with widespread 90's across the area. We turn wetter and a little cooler over the weekend with rain chances - but not a washout for much of the weekend.

Low temperatures this morning ran between 5 and 7 degrees below normal for late July. The lowest I found was the 55.1 degree reading at Warwick Township. Another beauty of a day today with highs ranging from the upper 70's at higher spots to the low 80's in valley locations. We start a warming trend back to near normal on Thursday and then above normal temperatures by Friday with some spots cracking 90 degrees for the first time in more than a month. Shower chances return over the weekend.

Get ready for our best stretch of comfortable summer weather over the next 3 days before we warm up by the end of the work week. Temperatures this morning dropped into the mid to upper 60's across the area. Today through Wednesday we will see highs not too far from 80 degrees with low humidity. Nighttime lows both tonight and tomorrow night may reach the 50's - open up those windows! The heat returns Friday in fact many areas that have yet to see a 90-degree day here in July may see it to close out the week. Shower chances return by next weekend.

Today will be our last warm and humid day till late in the upcoming work week. Temperatures tomorrow and Tuesday may struggle to escape the 70's. Nighttime lows should reach the low to mid 60's tomorrow morning and the upper 50's by Tuesday morning. This will be a great chance to open up those windows and get some fresh air in the place! Any shower chances look to be later today with the cold front. We start a warmup by Thursday with 90's possible to close out the work week.
