There has been some light showers and drizzle across most spots in Chester County this morning. Here in East Nantmeal we have picked up a scant 0.04" of liquid gold - we are over 2.50" below normal so far here in September....but still running on a surplus of over 3 inches for the year to date. Shower chances will continue till tomorrow before we clear out and cool down over the weekend. By the end of the weekend and start of the new work week temps will struggle to escape the 60's in higher spots with lows well down into the 50's with even some 40's again in the lower elevations across the area. Chester County records for today: All records at Phoenixville" High 96 degrees (1942) / Low 33 degrees (1986) / Rain 5.07" (2004)

Clouds should rule the sky through Thursday with small rain chances the further north and west you are from the Delaware Valley.....so for most of Chester County not much more than 0.10" or so of rain if that much! It will be increasingly muggy but temps will remain in the 70's for highs with nights in the low 60's before we turn cooler again for the weekend. By Sunday the higher spots in the County will struggle to escape the 60's for high temps. Chester County Daily records for today: All set at Phoenixville High 95 degrees (1942) / Low 32 degrees (1986) this was the earliest recorded freezing temperature in Chester County history. / Rain 5.90" (1999)

Several of the lower spots in Chesco dropped into the 40's overnight with the lowest being the 46.1 at Warwick Township higher spots like East Nantmeal could go no lower than 53.6. We should not see overnight lows that cool again until next weekend as we have an increasingly cloudy more humid and possibly wet week on tap starting tomorrow night. Rainfall still does not look that impressive unless you head south and east of Philly but we can hope. Chester County daily records for today: High 96 degrees at Phoenixville (1942) / Low 36 degrees at West Chester 2NW (1983) / Rain 7.85" at Coatesville 2W (1999) this was associated with the rains from Hurricane Floyd the 2 day total was 8.31" at Coatesville but over in Thorndale (where I lived at that time) we picked up a 2 day total of 8.61" of rain.

Reading Airport trying to get as warm as PHL....RDG is now somehow warmer than the hot spot of their southern neighbor in Chester County - Phoenixville thanks to their climate change warming....

Another couple of nice late summer days but a bit cooler tomorrow... before we see clouds and shower possibilities increasing from Tuesday through the end of the work week. There is a wide range of model rainfall amounts across the area....hoping some of the more generous models become reality this week. Chester County Records for today: High 95 degrees at Phoenixville (1927) / Low 34 degrees at Phoenixville (1985) / Rain 3.10" at West Grove (1966)

Another calming voice who is not a climate alarmist.....Meterologist Steve DiMartino. from NY NJ PA Weather - from his post today. "So, unlike many others, I am going to answer this question. 1. People like Al Gore and others calling Climate Change an emergency or an existential threat have done more harm to understanding Climate Change than any person denying climate data. So let me be clear: we are not on any trajectory, nor have we ever been on one now where NYC or Miami will be under water any time soon. Can that happen in 100 or 200 years? Sure. Why? Well, because there is a lot of gradual change happening geologically (its been sinking since the end of the ice age) and a gradual rise of the sea (rough 0.14" per year), eventually these cities will either have serious flooding issues constantly or will be under water. Not in a decade or even three, but in hundreds of years, yes.No matter what we do, use coal or go carbon zero, we will have storms. This idea that powerful storms will become less likely is again, idiotic. People blaming every storm on climate change are doing so to drive emotion and nothing more. 5. This scientist has no issue with addressing your questions, but please don't blame me for the statements of an idiot politician"

Hopefully the tropical potential will impact us with some much needed rainfall starting the middle of next week!! fingers and toes crossed!!

The great stretch of late summer / early fall weather continues across the area with similar temps and low humidity almost every day through at least Tuesday. Highs will remain in the upper 70's to low 80's with some early morning fog possible each day and seasonably cool nights in the 50's. Next needed rain chances may appear by the middle of next week with a potential tropical disturbance along the east coast. Chester County Records for today: High 98 degrees at West Chester (1983) / Low 35 degrees at Phoenixville (1977) / Rain 5.96" at Phoenixville from the impacts of Hurricane Donna (1960)

The 1st 10 days of September have been the 2nd chilliest start to the month in the 21 years of records I have here in East Nantmeal...only 2017 got off to a chillier start. Our slow moderating trend continues today through the weekend with temps reaching the low to mid 80's by the weekend but continuing comfortable humidity and seasonably cool nights. Chester County records for today: High 99 degrees at Coatesville 1SW (1897) / Low 34 degrees also at Coatesville 1SW (1924) / Rain 3.86" Morgantown/Elverson (1960)

Per our friend Chris Martz "Stare at it 'til your eyeballs are strained and they fall out of your sockets. Then, when they do, finger them back in and stare some more. The plot below shows the Conterminous U.S. average mean temperature by year from 1895 to 2023. The blue curve shows the average computed from the raw (measured) thermometer data. The red curve shows the average computed from the reported (adjusted) thermometer data. The actual temperature data indicate that there has been a statistically insignificant warming trend in the U.S. since 1895. The reported data suggest that there has been a very large warming trend by almost 2°F since 1895. Nearly all of the warming is a result of arbitrary adjustments due to the supposed “Time of Observation Bias,” or T.O.B.S. for short."

Today will likely be our 8th straight day with below normal temperatures. But beginning tomorrow we should warm to near and then above normal as the week progresses. No rain in sight for this week. Chester County records for today: High 97 degrees at Kennett Square (1897) / Low 34 degrees at Phoenixville (1986) / Rain 4.95" at Hopewell (1987)
