Light rain under the yellows here. S of the turnpike wins again. 

I picked up .09". Really, and uncannily, these suckers are riding almost the exact same track as yesterday. It's really the Rt. 30 corridor and south that's getting wamboozled right now.

.02” rain today

Low of 71 with .15” of rain. Been quite a four day stretch here. Today looks like a perfect river day, might have to hit it.

zero rain yesterday except for a few drops.

Continued warm and humid through Tuesday before we start a welcome cooling trend which by Saturday morning will see some locations with lows in the 50's with highs by the end of the week in the pleasant 70's. Best chances of any rain will be Monday night through Wednesday

I had a request to update the "heatwave" stats to something potentially more meaningful. Which is 3 or more consecutive days with daily maximum temperatures above the 90th and 95th percentile for all Chester County Stations. The below rank summary makes the absolute-vs-relative divergence concrete. Sorted by absolute rank, the biggest movers are the 2010s (11th → 4th) and 2020s (13th → 6th), both rising 7 places once heat is judged against each station's own norm — meaning recent decades have been locally extreme even though they weren't absolutely record-hot. Going the other way, the 1960s (−4) and 1990s (−5) fall under the relative lens, and the 1940s slip from 1st to 3rd. The 1930s hold firm near the top under both definitions, and the 1950s actually take the #1 spot under P90
