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.

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.

Too many folks don't know what a great tool that is to get past the junk we don't care about - glad you can mute me Voyager!! That said I am only 7 miles from Lancaster County so like you I cross over....

From Ryan Maue x feed on the NYT article: "It's official: without climate change, the ongoing Eastern United States heat wave is "virtually impossible" Climate scientists performed an autopsy of this week's weather and determined that it could not have happened in the past 500-years w/o the burning of fossil fuels" Q. Can the they do an autopsy the hottest decade on record the 1930's and explain that one for us too? RM. Their study started in 1950, so anything that happened before would not be relevant." LOL!!

1st 100 degree reading here on the island in SIC since I have had a station 2012

East Nantmeal current temp is 92.7 the high has been 93.0. This is the 3rd consecutive day I have reached 90 degrees. This marks only the 8th "heatwave" I have recorded in my 23 summers here in EN since 2004. Of note my poorly sited rooftop Tempest has gone 95.4 / 98.2 / 94.8 the last 3 days vs my VP Pro 2 with 93.0/94.8/91.0
