First mow of the season where I was kicking up some dust. July totals here sit at 3.10”, most of that falling early in the month. Storms in the forecast for the weekend.

82F/DP 65F

Wow we have double down here. 6.2" on the month. But vast majority of that was in 2 events earlier in the month.

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.

Started hearing katydids this week. Still looking for cicada bees to make their appearance.

I saw a few flying around in the backyard 2 total while I was cutting the grass this on Monday.  The hornets typically nest into my small hill along the driveway in mid-July I don't see them yet.

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.

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.

Need the rain now - seriously!

I also heard a cicada so loud that the sound was audible through the brick walls and almost sound-proof windows! :lol:

Currently 95 here with dp an awful 80. :yikes: Some fair weather cumulus are bubbling up too.

DAMMIT!  Got maybe 20 drops from that line. Literally nothing measurable enough to tip the bucket, let alone wet the street and walks.  The heavier stuff bubbled north and south of me.  It did drop the temp about 15 degrees from my 96 high to the current 82 with dp 75.  Currently mostly cloudy and hope something will bubble up or I'll have to pull out the hose.

I finally managed to get 0.02" overnight before midnight, which was not really enough but I guess it kept me from a total miss. :huh:  Still have to pull out the hose.  My Upper Darby sis said they got a deluge with near an 1".

After a 73 low yesterday, my high did end up being 96, making it 11, 90+ days in July so far. With the 8, 90+ days in June (with one of them being a 100), that takes me to 19 for the season at post time.

Currently partly sunny and 75 with dp 73.

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.

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.
