Below is the Chester County area Climate Summary for August 2026. August finished just slightly above normal +0.6 degrees as the 52nd warmest and the 16th wettest since 1871. Through the 1st 8 months of 2026 we are running 0.7 degrees below normal temperature wise which is the 57th warmest over 151 years but only the 103rd warmest on a composite anomaly basis.

91/76 here in Lebanon with a HI of 103 right now. Thermodynamic environment primed for explosion but will the fuse get lit later? Time will tell

Below is the summer (June-July-August) temperature summary for 2026 and summer temperature history from 1871-1926. This was 33rd warmest summer but overall since 1895 there has been no statistically significant warming or cooling across both the raw and composite trend and only the NCEI adjusted averages indicate any significant summer warming.

What looked like several days of temps in the 90s this week might end up with only one day. Today is a maybe, tomorrow is a likely not while Thursday "seems" to be a lock or close to it.

93 currently. Looks like we'll get 2 days but no heat wave. Back door cold front to the rescue tomorrow.

 There's some slightly enhanced kinematics ,slightly enhanced sheer profile north of my area.
