f the summer (Jun-Aug) ended today this would be our 18th warmest summer since 1894 with an average temperature at 73.8. With the somewhat cooler weather on tap to close out August thinking we may just miss out on the top 20

AM Low 66.6 on VP and 65.8 on Ambient - just missed heavier rains to my west and south last evening. While it's been 2x normal rainfall this month here...nowhere near the all-time wettest August of 17.81" back in 1955....however some spots to the south and west are already into double digit rainfall for the month!

Our morning low today was 61.3. Today in Western Chester County marks the 1st time our average low dips into the 50's for the 1st time since June 26th. Our average low will not touch the 40's until September 30th

AM Low this morning 65.0

Nice day in Western Chester County PA and a perfect day down at the Jersey Shore in Sea Isle City NJ - see my attached drone shot in SIC late in the day with a firm sea breeze all day and a high of only 76.3 In Chester County PA - today actually marks the last day we average a high temperature above 80 degrees....the next day we average over 80 degrees here in the philly burbs will be on June 24, 2021

The 1st day that failed to at least reach 70 degrees since June 2nd here in Western Chester County PA - also only the 2nd chilliest high on August 16th since 1983. With today's rainfall we are now 124% of normal rain this year

This morning's low of 64.7 was our lowest since the 63.3 on July 15th. How warm has this summer been? Well... here in Western Chester County PA this is the longest stretch without a temp in the 50's going back to 1983...our last sub 60 degree reading was on June 17th. In fact only in one July in addition to this year did we fail to record at least 1 day in the 50's - that was in 2012. In that year we went 52 days - between June 27th and August 19th without a low in the 50's. We have never had an August without a low in the 50's....could this be the year? Is global warming finally arriving in East Nantmeal?

So how warm of a summer has it been? Well If August Ended yesterday here in Chester County PA (outside the PHL heat island readings) the full summer months of (June-July-August) would have averaged as the 10th warmest summer (1894 to Present). However, both averages and actual readings will be declining through months end so more like a top 20 appears likely. Below are the top 10 summers in Chester County since 1894 and their average temperatures. (1) 1900 - 75.8 /(2) 1999 - 75.1 /(3) 1901 - 75.0 /(4) 1944 - 75.0 /(5) 1955 - 75.0 /(6) 1943 - 74.9 /(7) 2002 - 74.6 /(8) 1898 - 74.5 / (9) 1988 - 74.1/ (10) 2020 (incomplete) 74.1 So when did we have the warmest summers (June/July/August) by decade? below are the 13 warmest decades (1) 1890's - 73.1 / (2) 1930's - 73.1 / (3) 1900's - 73.0 / (4) 1910's - 73.0 / (5) 1940's - 72.9 / (6) 1990's - 72.6 / (7) 1950's - 72.3 / (8) - 2000's -72.3 / (9) - 2010's - 72.2 / (10) 1920's - 72.1/ (11) 1960's - 72.1 / (12) 1980's - 72.0 / (13) 1970's - 71.5

79.9/73.7 splits in Sea Isle City NJ and 85.3/71.4 on my 2nd station in Chester County PA

Plenty of 90+ temps at all stations with the exception of rounded up 90's at KMQS and KPTW at 89.6 and KMPO at 84.2 and of course my 2 stations in East Nantmeal at 88.2 and 87.8

5.83" on the Vantage Pro in East Nantmeal Twp in Chester County PA - will likely be revising this up once I check the manual gauge. Either way this is the 2nd greatest daily rainfall in Chester County history back to 1894. The only wetter day was September 16, 1999 with Hurricane Floyd when 8.28" of rain fell. Power out both here in Sea Isle City NJ and home in Chesco.....

64 mph gust here in Sea Isle City NJ

Just had the highest wind gust I have ever recorded in Sea Isle City NJ of 60mph on my roof....rainfall back in East Nantmeal Twp PA now up to 4.60"

Just had a gust to 57mph in Sea Isle City...plus a reported Tornado on the ground just 2 miles north of here in Strathmere NJ Rainfall in East Nantmeal Township now up to 3.28"

East Nantmeal Twp up to 2.70" of rain and pouring. Here in Sea Isle City NJ my weather station is back up with winds gusting as high as 45mph - saw a gust on the station at the Ocean Drive bar hit 55mph...just heard on scanner and pole is down back near the bay and into a house...no injuries

1.36" so far in East Nantmeal....heaviest rain so far has remained to my east...0.56" in last hour. The numbers I will report today are from the Vantage Pro which normally under reports rain. I will update tomorrow when I am back in Chesco and check the manual gauge. I am riding this out down in Sea Isle....winds are howling....unfortunately my vantage vue is having battery problems so hoping we get enough light to get it back on line to measure some of these gusts!
