Think you may need to check your siting or thermometer...no spots across all of PA with the exception of the PHL airport heat islands even got to 82 degrees....

Wow what a difference across most of Chester County with some elevation ...East Nantmeal could do no better than 76.1 and KMQS Chester County Airport only made it to 77.0....you are in a very warm spot...assuming a low elevation in the Reading PA area

Beautiful day down the shore in Sea Isle City NJ. Nice breeze off the chilly 62 degree surf temp

Our record high Chester County temperature today is the 92 degrees on this date back in 1969. The record low is 35 degrees set back in 1949. Record daily rainfall was the 3.05" that fell back in 1990.

We received a total of 0.61" of rain with the storms yesterday and overnight. Our record high temperature for today is 94 degrees set back in 1941. The record low was also the latest freezing temperature in Western Chesco history at 32 degrees this day back in 1927.

The record high today is 92 degrees from 1991. Record low 38 degrees in 1926. Daily rainfall record is the 1.92" from 1952.

No measurable rain overnight. The record high for today is 91 degrees set in 1964. Our record low is the 30 degree reading today in 1956. Of note that would be the 2nd latest freezing temperature ever recorded in Western Chester County. The latest freezing temp occurred on May 28, 1927 when the low was 32 degrees.

You are the best!! I will be diving in to this data....the weenie that I am!! Thanks again!! Paul

Our record high today is 95 degrees from 1941 - record low temp is the 34 degree today in 1963. Record rainfall is 2.59" from 1915.

With the exception of Mount Pocono....almost all spots reached or exceeded 90 degrees today. Of course to no surprise here in East Nantmeal we could NOT reach the 90 degree mark....with the exception of my Tempest weather station which is mounted on my roof (which did reach 90.7 degrees). However my Vantage Pro 2 (which I use for my "official" reports - mounted 5 feet above the ground and my Ambient Weather station also mounted 5 feet above ground level reached 88.1 and 88.0 respectively - I see nearby Bucktown also could do no better than 88.5. No doubt many spots under 600 feet across Chester County reached the 90 degree mark. The Chester County Airport (KMQS) almost exceeded...but topped out at 89.6.

Wow!! this is excellent information that I have never seen!! It appears he was submitting obs back to February 1888! The earliest obs I can find from him are those from January 1894. Will have to do some digging to see if anyway to unearth those additional years! To have tracked daily data for 42 years is mighty impressive. Maybe I can reach that number of years if I am still around!! Thanks for the most excellent research!!! Paul

Can we touch 90 here in NW Chesco? My VP is at 86.0 - the rooftop Tempest is at 88.0 and my Ambient station is at 85.3

I kind of miss our obsessive friend from the valley!! Thanks for sharing!!

Would love to know more about him and the guy that followed him Howard Pyle....let me know! Thanks! Paul

Of note we have not had a 90+ day in May since May 3, 2018. In that year we ended with 4 days above 90 that summer. The last time we had earlier 90+ temps (April/May) was on April 26 and 27, 2009. In that summer we never again saw a 90+ day as those 2 were the only times we were able to crack 90 that year and 1 day was 89.5. Before that our last 90 in May was on May 4, 2001.

Most of the heavy storms passed through far NW Chester County and into Berks County. However, with the frontal passage temps have fallen off pretty quickly by about 10 degrees in the past hour. The current temperature here in East Nantmeal is 62.3 down from 73.1 about 1 hour ago. Rainfall at least here in East Nantmeal has been light with only 0.07" of rain so far today. Should be a beautiful couple of days on tap both Tuesday and Wednesday with temps a little cooler than normal in the upper 60's to low 70's and lots of sunshine! A very brief warm up to above normal temps by Friday/Saturday with out 1st possible 80 degree readings across the County by that time. However, quickly back to slightly below normal temps again by the start of the new work week as we head toward Memorial Day weekend.
