ChescoWx

Rain chances increase again later this afternoon with the best chances between 3pm to 8pm. A couple beautiful days on tap both Sunday and Monday with temperatures slightly cooler than average for mid-July. We start a solid warm up on Tuesday and may see widespread 90+ temps for one day on Wednesday. Still hot but "only" in the upper 80's both Thursday and Friday.

Nada in NW chesco too

Who can spot the significant warming of the USA away from our urban heat islands?? This looks a whole lot like Chester County PA - I bet you NCEI chilled the 1920's and 1930's - I always said there is no climate fence around any county!

I hear this is his first stop! LOL!

After our heavy rain across much of Southern Chester County yesterday today will feature some additional shower chances both today and tomorrow with a slow-moving cold front. High temperatures today will be near normal in the low to mid 80's. A bit below normal over the weekend before we warm to the upper 80's on Tuesday and near 90 degrees both Wednesday and Thursday.

Great news for climate scientists and bad news for climate alarmists with this appointment of Dr. Weilicki to lead the U.S. Global Change Research Program!! From Secretary Chris White "Matt Weilicki is an honest scientist who follows the data wherever it leads. That is what science is all about. He will lead our efforts to honestly present the empirical climate data to guide policy makers. Sadly, too much of the mainstream climate community has focused on a scary narrative that is inconsistent with actual climate data, leading so many astray like reporters at Politico. I welcome the new era where data, not rhetoric, is the arbiter of truth. Growing the government, increasing energy prices, and scaring children will no longer be the goal. Science will be the goal. So happy to have Matt in this role!"

The telltale sign of having no answer to the science/data is when someone like Charlie attempts to push the falsehood of something he deems "settled science". Science is of course never settled but constantly evaluated and tested which I do constantly. There is clearly no mistake in the table as it it actual validated raw data.....the real mistake is Charlie and NCEI thinking Chester County on average is colder than Allentown. Plus Charlie I love your line "between 1927 and 1951, the County COOP stations are much warmer than the county average" Welp I included all of the COOP stations so again exactly which station? since all are included above? Also, how do you know in fact during those years the county stations were according to NCEI in reality colder than Allentown? Real science over feelings FTW!!

The haves - Southern Chesco and have nots Northern Chesco continue with some rain totals today as of 645pm DEOS stations - Atlgen 0.93" / Longwood Gardens 1.43" / Nottingham 1.96"/ Kennett Square 2.17" / West Grove 1.28" / Atglen 0.99" / West Bradford 1.03" / West Chester 0.34" / Chester Springs 0.00" / Glenmoore 0.04" / Warwick 0.04"

Revisiting that old topic that no one seems to be able to answer - not the why they did it - but how exactly or where exactly did NCEI look for their control COOP or analog station to support their chilling adjustments of the historical raw data for Chester County PA. Again we focus on the 25 year period of greatest adjustments to the raw data from 1927-1951. I think I may have found the station they use as the adjusted NCEI data is very close to this station. However, one big problem is this station sits a couple counties and 30 plus miles north of Chester County. I looked to the NWS COOP Allentown PA site which was the Allentown Gas COOP site. This station was the primary Allentown climate station prior to ABE. Of note NCEI chose to chill Chester County to actually lower than Allentown PA in 20 of these 25 years! Keep in mind again in 20 of 25 years there is no actual NWS COOP site in the county that was as cool as the post hoc NCEI County averages. So overall NCEI believes that Chester County is colder than Allentown....

A flood watch is in effect through midnight for the potential of some heavy rain. Some isolated spots could see the rain fall at 1" to 2" per hour. No doubt with our rain deficit let's hope we all see some beneficial rain today! Additional shower chances tomorrow before we start to clear out on Saturday. Today will be our 4th straight day with below normal temperatures this should continue through the weekend before we warm to normal on Tuesday in the mid-80's and above normal with near 90 by Wednesday. It looks like great weather for the All-Star Game in Philly next week.

Yesterday's high here in East Nantmeal was only 72.7 this set a new low maximum temperature for the date set back in 2005 of 73.7. Another below normal temperature day today with highs not far from 80 degrees. Shower chances increase tomorrow afternoon and again on Friday into Friday night. Temperatures remain near normal through the weekend before warming a few degrees above with highs by the middle of next week in the mid to upper 80's. Does not look like any return of 90 degree plus reading across the county for the foreseeable future.

Some light showers have been around this morning, and we will continue with some small chances of these through the day. We clear up tomorrow with what looks to be our best weather day of the week with sunny skies and highs several degrees below normal July levels in the upper 70's to near 80. Our next chance of showers and storms looks to arrive on Thursday night into Friday morning.

Some rain totals from the storms last night. DEOS stations at Atglen 0.72" / Chester Springs 0.48" / Devault 0.66" / Glenmoore 0.60" / Kennett Square 0.42"/ Longwood Gardens 0.18" / West Bradford 0.51" / Nottingham 0.54" / Warwick 0.42" / West Chester 0.19"/ West Grove 0.13" / KMQS Airport 0.46"/ KOQN Airport 0.10 Our run of 90+ days should end today for most folks across the area. In fact looking ahead at least I suspect we may not see another 90-degree reading for the next 10 days. This week will feature below normal temperatures through Wednesday with highs tomorrow through midweek in the mid to upper 70's. It will however be a wet week with rain chances later today through Tomorrow night and again Thursday into Friday. The driest day looks to be Wednesday.

Thanks pasnownut!! right back at you!!

Happy 4th of July to all of you! Below is the history of July 4th weather since 1893 here in Chester County PA. Overall we have seen a flat trend in average temperature / a slight cooling trend for high temperatures and a slight warming trend for overnight low temperatures for the holiday. The hottest July 4th was back in 1966 the chilliest was in 1978.

Thank you so much!!! I appreciate all the folks that post in this forum and others!!

Happy Independence Day to all!!! Well while today will still be sweltering it will be a few degrees cooler than yesterday. Real relief arrives tomorrow as temperatures fall back to near normal levels for early July with highs in the mid-80's. We will see temperatures fall to below average by Monday and continue through the middle of the week. Shower chances start to increase this evening, but I think the best chances for rain will be after fireworks. Rain chances really increase Sunday night into Monday morning. Some spots could see between 1 to 2 inches of much needed rain.
