They must read the forum.

Fox 29 in Philly posted the below graphic for Philadelphia at the PHL Airport regarding "heat wave" days. I have also posted the same analysis for Chester County since 2020. Of note 10 of the Chester County stations have had the same or less than the 7 heat waves at PHL this year over the entire 2020's!

Dropped to 52 before the low clouds filled in. The sun sets before 8 now, and the sun reaching into m bedroom during the evenings is waning fast.

A signal for cooler and drier air in the extended, even down my way. It's just a subset of guidance, but seems to be growing.

For those interested in the very early accuracy of the ChescoWx model forecasts vs. the NWS - so far with a couple complete days all model runs ran cooler than the NWS Forecast and the actual verified temperatures were cooler than the NWS Forecast with ChescoWx at least over a couple full days being closer to the actuals. But it is only a couple of days so we will keep tracking. The first column is the forecast run time with the green shaded being ChescoWx and the unshaded column the NWS forecast.
