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!

Suspect today could be our last chance this year of a 90+ day here in Western Chesco. Even if we fail to touch 90 again....the 5 such days already recorded this year are the most since the seven (7) 90+ days we recorded in 2012. For more good news for those sick of this heat....our last average day with a high in the 80's is August 17th - with our average high of only 77.7 by the end of this month! On a wet note the WXSIM prints out 4.49" of rain from the tropical storm this week....we shall see! We could use some rain as while we are still above normal we have not seen any rain in the last 8 days.

My ambient weather station split today was a bit cooler than my Davis Vantage Pro at 85.8/68.7 vs. the Vantage Pro at 85.9/69.5

July in Western Chester County PA ends as the 14th warmest July and our warmest since the same 77.0 average temperature in July 2011. Also with 5 days that at least on a rounded basis exceeded 90 degrees this month marks the most 90+ days in the county since the 7 such days also back in July 2011. Of interest 9 of the top 10 hottest July's in the Western Chesco data set occurred prior to 1955 with only the hottest July on record 1990 cracking the top 10 all-time hot July's in the last 65 years. Below are the top 10 July's on record for Chester County PA 1999 - 80.0 / 1901 - 79.2 / 1955 - 78.9 / 1921 - 78.8 / 1944 - 78.7 / 1900 - 78.3 / 1943 - 77.8 / 1898 - 77.3 / 1931 - 77.3 / 1935 - 77.3

Missed on the rain to the north last night...

Most of the normal hot spots over 90 again today with the exception of the non-heat island spots including KMPO/ Andover / Belmar / KMQS /KPTW and of course the 2 stations in East Nantmeal all failing to reach the 90 degree mark today

Most locales recorded yet another 90+ day with the exception of Lehighton, KMPO, Andover, Sussex, KPTW (Pottstown) and of course East Nantmeal!!. KMQS did record a "cheap" rounded up 90. Down in Sea Isle City a 2nd straight day of strong west winds killing the sea breeze leading to a high temp in SIC of 92.0 and the highest heat index we have seen all year on the Jersey Shore of 103.7

Where 90's come to die in the philly burbs of Western Chester County....again no luck with the 90s

By decade below are the top 10 warmest July's since 1900 in Western Chester County PA 1 - 1900's - 75.6 2 - 1940's - 75.5 3 - 1930's - 75.3 4 - 1910's - 75.2 5 - 1990's - 74.8 6 - 1950's - 74.3 7 - 1920's - 74.2 8 - 1980's - 73.8 9 - 1960's - 73.7 10- 2000's - 73.3 11 - 1970's - 72.4

Here in Western Chester County PA through yesterday the average temperature for July 2020 is at 76.0. If the month ended today that would be the 22nd warmest July since 1894. We have a great shot to finish with a top 20 warmest July...however a top 10 is unlikely. Below are the 5 hottest July's on record 1999 - 80.0 / 1901 - 79.2 / 1955 - 78.9 / 1921 - 78.8 / 1944 - 78.7
