Happy 4th again! Below is an analysis of our climate here in Chester County for Independence Day. As you can see overall in our 132 years of weather records back to 1893 we have seen an overall slight cooling of our high temperatures and a slight warming of our low temperatures. Not surprisingly our average temperatures on the 4th of July have remained mighty constant with no warming or cooling on average over the last 13 decades of weather observations.

Happy 4th of July to all of you! It should be an outstanding day for all of your outdoor activities with family and friends. Several of our colder spots had low temperatures this morning in the pleasant 50's. Tonight we should see even more spots reaching the 50's for lows by morning. Today we will see much of the day with temperatures in the upper 70's to low 80's - this is a couple of degrees below normal for the 4th of July. We start a slow warming trend tomorrow with our warmest day looking to be Monday with highs into the upper 80's. Still no 90 plus days in our future...in fact in looking at some of the longer-range models we might not see such a day through at least July 20th! The weather gets a bit unsettled with some shower chances almost each day of the new week - although no wash outs!

It's all ghosted fake data - no doubt that adjusted data is exacty what they use on CinCin TV networks to show their man made "warming" climate

The Queen City in Ohio joins the altered past climate group.....there really is a pattern here!

Where's the chilling for the recent years ongoing UHI problems at PHL???

Who can spot that same chilling of the past data in the SE Pittsburgh Burbs?? Do we see a pattern chill the past!!

Who can spot the UHI chilling adjustments done to the PHL Airport data?? Hmmm I guess there is no UHI amidst the runways and jet exhaust....

I've matured and removed the word from my vocabulary.....LOL!!

Pittsburgh like so many others spots including Chester County...let's just cool those pesky 1930's and 1940's ...it always gives us the answers we want....

@TheClimateChangerlet me help you our with a broader view of the entire USA.....say hey to the 1930's!

Heck we might eventually get a warm as we were back in the 1930's in our current cyclical warming cycle.....

Imagine if we could actually see the actual real raw US average temperature trend?

fixed it for you - The NOAA method is well proven for getting the DESIRED answer

Look at how close these 2 stations are in NE Chesco....certainly not representative of the county climate

The Phoenixville and Spring City sites that are now the only remaining NWS COOP stations of course run warmer than all other stations in 24 of the last 25 years. On average a 0.8 degree variation. With those sites running as much as 3 degrees too warm in one year and at least a degree warmer in 15 of those years!! Makes very little sense as these 2 stations are much lower in elevation and near each other in the Northeastern section of Chester County....yet these are the 2 stations that NCEI will use to calculate their county averages.....call me stunned!! LOL!

Below are the stations used and dates operational

A view of our summers by decade here in the Philly burbs of Chester County....without the typical chilling alterations of the past and warming the current....as always not much warming at all.

A beautiful stretch of weather is underway for the 4th of July holiday weekend! Today will be our warmest day until Sunday. We should see highs today in the mid 80’s. We cool a little tomorrow to slightly below average temperatures for the 4th of July with our highs in the lower 80’s. Our next chance of rain looks to arrive by Tuesday evening.

2.11" of rain so far today in East Nantmeal and 2.94" since yesterday.

We generally saw between 1" to as much as nearly 3" of rain across Chester County last evening and overnight. Some spots like West Bradford received 2.92" of rain with Glenmoore at 2.06" and East Nantmeal with 1.73" of rain. We could see quite a bit more rain later today as a cold front approaches from the west tonight. The NWS has issued a Flash Flood Watch from 2pm through 2am Wednesday. The NWS has a forecast of another 1" to 2" of rain but some of the shorter-range models show even more across some spots. Today will be our warmest day of the week with highs in the upper 80's. We fall back pretty close to normal or a bit below tomorrow with near normal temperatures through Saturday before we warm back to a few degrees above normal by next Sunday. No 90-degree temperatures are expected at least in the higher spots of the county throughout the week.
