Central PA Summer 2025

Heat advisories up. And they put this in today’s discussion.  
 

Ensemble data suggests pattern change is likely to evolve by
the end of the forecast period/beginning of August as the upper
level flow becomes more amplified, with the ridge building
north across the Rockies and a trough from Canada building
southward across the Great Lakes and the Northeast. This should
bring a return to much more pleasant conditions behind a cold
front on Thursday.

Yeah there's been some heavy hints in the modeling for a while now that the first week of August could be on the cool or comfortable side.  Don't think anyone would complin about that.  I'm sure the heat will return not too long after that.

Boo this man!

Low of 70 with dew points on the rise.

Got down to 72 here. It’s 79 at 8:50 and very humid

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.

[ChescoWx]

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.

Yesterday was not too bad....today, it is BRUTAL.

Pretty impressive to see 3,000 ML-CAPE in the LSV at this hour. Id expect some pretty gusty wet microbursts in a couple hours as the PWATs are increasing above 2.0” in the same region

It just got wild here - incredibly windy. 40-50 mph stuff.

Got real dark, real windy, then that line collapsed and I got sprinkled for a minute.

Had .43 from that thunderstorm. Lots of heavy thunder.

Not much in Tamaqua, but it was bad down between Hamburg and Reading on PA61. Easily 40+ gusts as it was ripping branches out of the trees, and actually looked like an Arizona dust storm prior to the rain hitting.

You know it’s humid when even a T’storm rolling through can’t drop the temp below 80. About a tenth of an inch here.
