This morning saw quite a few valley spots across the area fall below freezing. Warwick Township our typical cold spot fell to 29.4 degrees. Here just a few miles south but 250 feet higher in East Nantmeal we saw a low of 36.7 degrees this was our chilliest morning since last April 17th when we reached 34.2 degrees. Higher ridge locations have still not experienced a frost or freeze so far this autumn. Our cool autumnal pattern continues this week with the potential of another coastal storm by mid to late week. This storm has the potential to bring some widespread beneficial rains to the area. We will remain with temperatures below normal through next weekend.

Plenty of lows below freezing across most of the valley locations including Nottingham, Warwick Township, West Bradford, West Chester, Devault with the lowest the 29.1 degree reading at Warwick. At our higher ridge spots like here in East Nantmeal we got no lower than 38.9 degrees this morning. Temperatures during the day have been running 5 to 7 degrees below normal during the last couple of days and this chilly trend looks to continue through at least the next week taking us into the first week of November. We stay dry till midweek when we will turn our attention to a possible coastal storm which may impact the region from Wednesday night into Friday.

The NWS has issued a Frost Advisory for tonight for the entire area. However, many spots below 500 ft ASL in Chester County have already seen multiple freezing mornings. Those valley spots may again see freezing temperatures while some higher spots could see some frost but likely staying above freezing. For the rest of October, we should see below normal temperatures with daytime highs falling from the upper 50's today to the low 50's for highs by the start of the new work week. Lows should be frosty most mornings with a widespread freeze possible by next Monday and Tuesday mornings. We stay dry until our next chance of showers on Tuesday night.

Some rare fair and balanced climate views.... https://www.dallasnews.com/opinion/commentary/2025/10/16/activism-has-damaged-the-climate-science-debate/

Most spots across the area saw between 0.10" to 0.22" of rain last evening through the overnight hours. With that frontal passage last night, we will turn back to below normal temperatures for much of the rest of the week and likely to finish the month of October. This means we will probably finish October with below normal temperatures. This would be our 5th below normal temperature month over the 1st 10 months of 2025. Our valley locations will likely see another freeze each morning between Friday and Sunday. The higher ridge spots (above 600 feet ASL) will likely see no more than some patchy frost and continue their growing (freeze free) season into November. The growing season has ended for most valley locations across our area. We look dry for at least the next week.

I think I am the only one who posts here every day....no doubt winter weather will bring the folks back home!!

Lows this morning ranged from as low as 33.6 in valley locations like Warwick Township to 46.8 at ridge locations like West Grove, Today we should we our warmest day of the week with some valley locations nearing 70 degrees. Higher ridge locations will remain in the upper 60's. A cold front crosses the area overnight tonight with some very light showers. After that we seem temperatures no higher than the 50's for highs and 30's for lows through the rest of the week and into the weekend. For those lower elevation spots that have already had multiple freezes this month you could see a couple more both Thursday and Friday morning. Higher ridge spots look to continue their growing season with lows remaining above freezing through the week.

Most spots across the area picked up between 0.10" to 0.25" of rain overnight. We could see another shower this morning before we clear up and turn windy. Today and tomorrow will be not too far from typical temperatures in the low to mid 60's. We look to turn below normal starting tomorrow night and that should last though the rest of the work week. Some of our valley locations that have already seen a couple of freezes may see another one by Friday morning. Our next chance of any rain looks to be tomorrow night into early Wednesday morning.

One last mild above normal temperature day today before some showers arrive after midnight tonight and turn us back to below normal temperatures for the rest of the upcoming week. Rain tonight looks like between 0.25" to 050" across the area. The only other chance of rain this week looks to be Tuesday night. Highs looks to be in the 50's and lows in the 30's for much of the late week period.

Got it! You can't find any proof in the Chester County data to undermine the quality of the data....unless we go hundreds of miles away - check!!

Of note today back in 1972 we recorded our earliest measurable snowfall in the county area. Between 1" to 3" of snow fell across the higher ridges of NW Chester County. Interestingly that winter of 1972-1973 ended up being the least snowy winter in County history. In fact, that is the only winter season that no measurable snow was recorded at Coatesville. No snow chances this season till next month. Today we warm nicely well into the 60's with low to mid 70's by tomorrow as we enjoy a little Indian Summer for those spots that have already seen a freeze this season. Rain chances to ramp up by Sunday night into Monday morning. We then turn chillier again for the upcoming work week.

You keep making the rookie mistake of trying to bring unrelated stations not anywhere close to the county in question. Some of those you reference are 25 to 40 miles away....that does not improve a poorly constructed argument or address the facts proven above.

Don the problem is your reliance or let's call it your faith (which is not science) that "IF what is modeled, proves accurate ...but conversely and it is certainly possible IF what is modeled proves inaccurate (which is of course not beyond the realm of possibility) the consequences you fear of what from today's vantage point in your world view seems foreseen and avoidable - in fact never ever comes to pass...would obviously mean there were in fact no consequences that we needed to avoid in the first place. Do you see why you are being called out by myself and others for your so called "thesis of doom" post?

Bravo! an excellent post! Too often folks bring in politics where it has nothing to do with the political whims of a democratic society like here in the US. Thank you!!

Is this thread not for climate change on a world wide, United States, State Level or County basis? I do present climate change thoughts on a county basis. For example I posted real climate stats showing climate change across Chester County regarding the number of 90+ days. That is a climate post correct?

Now that we are done with any 90+ degree days. Below is the by-decade trend of the average number of 90+ days across Chester County PA from the 1890's through the 2020's. There is a clear decline at all elevations in the number of such hot days. In fact, the 2020's are trending to be the 2nd lowest number of average 90-degree days behind only the 1970's.
