Below for the Philly burbs of Chester County PA are the all-time May climate records and below that the climate trends for the month. Based on the actual historical data (blue) our average May temperatures show a slight cooling trend since 1893 while the adjusted NCEI (red) temperatures indicate a very slight warming trendline.

LOL!! but it is the only 134 years of data we have for this beautiful county of Chester....so we analyze!!!

I simply posed a question I did not say it was proof of anything...I unlike some understand when the n is way too short - LOL!!

Today will be our 7th consecutive below normal temperature day with our temperatures remaining below normal through this weekend before we warm to above normal by Tuesday. We then turn cooler again for the rest of the first week of May. Overall, the long-range models see a chillier than normal month with some models continuing the relative chill into June. We have some slight shower chances tonight with rain chances increasing toward the middle of next week.

East Nantmeal finished with an April temperatures of 54.6 (+2.0 degrees above the 2003-2025 average) this is good for the 5th warmest April across 23 years of records. I am working up the overall Chester County climate records today and will share later. Overall with records back to 1893 we should come in close to a top 15 warmest April.

Today was our 6th straight below normal temperature day and we picked up another 0.04" of rain this evening with the passing shower.

Fortunately we have leadership and the people coming around to the climate grifts that have been taking place with folks like Al Gore...but c'mon chesco don't be a denier - there is clear scientific consensus - you know that 97% consensus story - LOL!!!!

LOL!!! OMG 131 years of history....what was the average temperature to the nearest 1c in Omaha NE in April 1779?? ridiculous cherry picking of small data history!

From our Administrator of the US EPA to congress "I'm also done with the likes of AOC, Al Gore, John Kerry, and the rest of the lying cabal that make stupid climate predictions, plunder tens of billions of tax dollars, enrich their well-connected allies, and are committed to strangulating out of existence entire sectors of our economy. Climate alarmist AOC wants to be taken seriously while also insisting the world is imminently about to end due to climate change (Just under 5 years remain on her nutty Jan 2019 prediction that only 12 years of life are left on Earth). Al Gore is now speaking publicly about his concern with global freezing after decades of grift talking about global warming. “Within the decade there will be no more snows of Kilimanjaro,” said Gore in 2006 (There’s still snow on Kilimanjaro year-round). Gore also predicted in 2009 ice-free Arctic summers within 5-7 years. John Kerry warned in 2009 that the Arctic would be ice-free by 2013. These people are dishonest, power-hungry hacks. The GREEN NEW SCAM is DEAD!!!

Below normal temperatures are likely for the foreseeable future. We also turn wetter with rain chances increasing tomorrow morning and especially tomorrow night. Each day trends a bit chillier through the upcoming weekend with highs by Saturday around 15 degrees below normal for the start of May.

Makes sense! thanks Mike!

Hi Mike - no doubt a silly question for you!! But in the AFD write up what determines unseasonably warm or unseasonably chilly? Is there a degree threshold above or below or subjective? Yesterday was in my view unseasonably chilly with temps around 10 degrees below normal values - yet in the AFD it said seasonably chilly. Thanks! Paul

We received between 0.50” to 1.04” across the County with more falling across the north with that higher amount recorded at the Chester Springs DEOS station. We continue with unseasonably chilly weather today with highs remaining around the middle 50’s. Tonight, we could see some patchy frost and even a freeze in some of our typically colder valley locations We moderate to near normal in the mid 60’s both Monday and Tuesday before we turn chillier again and wetter by mid-week.

Unseasonably chilly weather this weekend with high temperatures more than 10 degrees below normal for the end of April. We have picked up 0.04" of rain so far today here in East Nantmeal and it looks like as much as another inch could fall across the area by noon tomorrow. Temperatures this afternoon will likely fall into the 40's by evening and reach the upper 30's by morning. We warm back into the low 60's but still several degrees below normal for the rest of the work week with more rain chances by Tuesday night through Wednesday.

Unseasonably chilly weekend on the way with temperatures at least 15 degrees below normal levels for late April. We start the cooling trend today with a backdoor cold front moving in from the northeast today highs should be at least 5 degrees cooler than yesterday. Beneficial rain arrives tomorrow morning and we should see rain a good bit of the time Saturday into Sunday morning with temperatures on Saturday remaining in the chilly 40's for high temperatures. We could see at least an inch of rain in many spots which is great news for our local farmers and green thumbs! We moderate next week but still a few degrees cooler than average with more showers possible by later Tuesday.

Today will likely be our mildest day for quite a while. We start a cooling trend tomorrow and it looks like our pattern over at least the next several weeks will feature generally below normal temperatures and above normal precipitation. Of note since March 1st we are at about 80% of our normal precipitation. We could pick up a 1/2 to 3/4 of an inch of rain from Friday night through Saturday. Saturday will be a chilly and raw day with winds off the still chilly ocean keeping temperatures not far from the current ocean water temp of around 50 degrees. Temperatures next week look to remain a little cooler than normal with rain chances increasing again by Monday night into Tuesday.
