Have shared variations of this before... but some clear strong consistency across the 3 longest running NWS Cooperative locations in Chester County...with the vast majority of the warmest summer (June thru August) decades occurring prior to the 1990s. Eight (8) of the top ten (10) warm summer decades at both Coatesville and Phoenixille occurred before the 1990's and seven (7) of the top ten (10) warmest summers at West Chester also were realized prior to 1990. That said - I note that the 2000's and 2010's would likely have ranked much higher with the change in Coatesville/Western Chesco obs to the higher elevation stations starting in the mid-1980's

Plenty of 90's across the low spots of Chesco with Marsh Creek at lake level already up to 96.5 while Hawk Hill in Downingtown up to 89.1 and 89.6 at KMQS and 90.0 at KPTW. Here in East Nantmeal the roof mounted Tempest has topped out at 90.9 degrees - but both the VP2 at 88.3 and the Ambient station (88.2) have not yet topped the 90 degree mark. Also 1st 90+ day on the barrier islands at the Jersey Shore!

Already up to 88.5 down at Lake Level on Marsh Creek and up to 84.3 here in East Nantmeal and 85.0 on my tempest roof top station....could we actually touch 90 here in Western Chesco for the first time since June 30, 2021?
