GFS simmers the region through the remainder of August except for one brief interlude of normal late next week.

 

The breaks help, imo. Something to look forward to.

Out climate summary for today in Western Chester County PA was a High of 83.4 and a  Low  of 73.3 for an average temp of 78.4  which is  6.2 degrees above normal .  Of note today marks the last day of the summer season that those of us in Chesco have an average high temp that will exceed 80 degrees until next June 9th.

That of course does not mean we will see more 80+ days like Sunday with even some upper 80's possible thru Wednesday but any 90 plus days seems well out of reach here in western Chester County

Only got down to 74F overnight. Had a brief shower this morning that made the humidity more humid.

Also, read Paul Pastelok's blog at Accuwx this morning -- while some comfortable air masses will move through, overall the end of Aug/start of Sept looks hot. Possible Sept analogs include 1993, 2004 & 2014.

It helps to have your station surrounded by trees and located at nearly 700 feet AMSL ;)

not all of Chesco, or even western Chesco, has those conditions.

Most of the NWS Western Chester County Zone (which is why Mount Holly split the zone) is above 600 ft ASL so yes - most of the zone has not had many 90+ days and should of course not expect many more this season.

90 or above for high temps today at all of the NWS/FAA sites across the 31 reporting stations across the PA/NJ and DE tri-state area with the exceptions of Mount Pocono at 84 / Cape May County 88 (Sea Isle City only 83.7 w/sea breeze effect) / Andover NJ 89 / and of course Western Chester County with KMQS at 87.8 and East Nantmeal at only 86.2 - marine influence and relative elevation FTW

Made it up to 91 here today with a low of 74.  The humidity was awful to boot with dews in the low-mid 70s much of the day.  Currently 77 and have been watching the storms firing north and west of here on and off...  Not sure if any will survive to fringe me but we'll see.

Fri - Sun look downright super nice (lows in the 50's?) once we get through this early-midweek hot-muggy mess.

The good news is the weekend looks fantastically awesome. The bad news is Thursday has been added as an extra for the heat wave, like all the rest this summer.

Pop-up storm is moving a few miles south of me and I had gotten up to 92 before it clouded up from that.  Down to 86 now although I expect it will go back up again since the sun just popped back out despite the threatening clouds all around.
