Eight years ago today we were in the middle of a snowstorm that would bring between 4" to 7" of snow across the county. A little different here today with today being our warmest day till Friday. Clouds are on the increase with a few showers possible by evening. Rain amounts look pretty light with under 0.10” A cold front crossing the area will move through overnight and we will see winds increasing from the west and temperatures dropping during the day on Sunday. Below normal temperatures for most of the work week with highs in the 40's and lows near or below freezing. We warm to near 50 degrees on Thursday with rain chances increasing by Thursday night.

Quite a few of our valley locations saw temperatures well below freezing this morning including Warwick Township (22.7) with a low more than 10 degrees colder than here in East Nantmeal (33.3). We moderate a bit today and especially over the weekend with temperatures reaching well into the 50's. Rain chances increase by tomorrow afternoon with a cold frontal passage, and we turn much chillier again by Sunday night. Temperatures next week look to remain below normal with highs in the 40's and low in the upper 20's for most spots.

Below are the Top 50 Snowstorms in Chester and SE Berks County History. Of note the 1960's had 8 of the Top 50 storms followed by the 2010's with 6 of our largest snowstorms. For folks that think we don't get snowstorms like the old days....we only need to go back to our last full decade! Of note so far here in the 2020's we have had only 1 storm in the Top 50 that one being the February 2021 storm that left 16.6" at East Nantmeal and 14.0" at Spring City.

Early glimpse of Christmas Week on the Euro Weeklies

Thanks Timmy boy! If only you understood and lived in the world of reality....but never mind! LOL!!!

And only 18% before 1955....interesting...not really cyclical climate in action!! LOL!!

Climate factoid of the day. Someone posted last week that it seems like it never snows before Christmas here in Chester County. So, I went back and looked to see how often we have not recorded any measurable snow by Christmas Day. The data shows we actually have seen measurable snow 92% of the time before Christmas. There have only been 11 years across 132 years of record that no station in the county recorded measurable (more than a trace) of snow. Those years were 1899 / 1918/ 1956 / 1965 / 1974 / 1991 / 1999 / 2001 / 2006 / 2015 and 2021.

I have continued to update the Chester County Weather website and have now completed and added a listing of the largest Chester County snowstorms across the 7 months of the year - October through April that we have recorded snow events. https://chescowx.com/top-snowfalls-by-month/ this includes the 2nd largest snowstorm in County history that occurred in March 1958 when between 19" to as much as 50" of snow fell across Chester and SE Berks Counties. See below.

Today should be almost 10 degrees warmer than yesterday...but still a few degrees below normal for mid-November with highs in the upper 40's to around 50 degrees. Temperatures look to stay near to below normal through Saturday before we briefly warm to above normal Sunday before falling back below normal to start the new work week. Our next rain chance looks to arrive Saturday night into Sunday.

If the below climate forecast model is to be believed....our area in the Northeast across the Northern Mid Atlantic would see some of the coldest temperatures relative to average over the next month through December 11th

Last night before midnight was our first below freezing temperature here in East Nantmeal since back on April 9th. That ends our freeze free growing season here in NW Chester County at 215 days. In the last 22 years the growing season has ranged from a few as 174 days in 2020 to 233 days in both 2005 and 2024. The earliest first freeze was October 13, 2012 and the latest November 23rd 2015. There has been some occasional snow flurries around the area today with temperatures remaining well below normal for mid-November with highs in the upper 30's. In fact, our high temperatures should stay below normal through the rest of the work week with highs remaining in the 40's in the hills and near 50 degrees in the valleys. We warm up well into the 50's by Sunday with rain chances increasing by then.

My early winter take for Chester County is a cold start to December. Slightly below normal December and near to below temperature January with near to above normal February. Well above normal March temperatures. Snowfall not too far from average seasonal snowfall. 1 storm over 12" and 2 over 6" Chester County - higher elevations 40" of snow. Valley locations 35" of snow.

Nice write up!! Thank you!!

Most of the area received some beneficial rains with between 0.30" and 0.50" falling since last night. Here in East Nantmeal we have already recorded our high for today at midnight at 53.1 degrees. Temperatures have fallen off to the low 40's across the area and will only rise a degree or two this morning before we see temperatures slowly fall this afternoon. We should reach the 30's by late afternoon and fall below freezing early this evening. Tomorrow will be the coldest day with highs not too far from 40 degrees. We should see well below normal temperatures continuing for the rest of the week with highs mainly in the upper 40's to low 50's.

Some sun this morning, but showers are possible almost anytime today and tonight. We could see between 0.15" to 0.25" of rain by late tonight. Today will be our last mild day with temperatures a couple of degrees above normal with low 60's in the valleys. A strong cold front moves through late tonight and we fall back to near 40 degrees by morning. Our high temperature tomorrow will occur at midnight tonight with temperatures only rising a couple of degrees tomorrow morning before falling to freezing by tomorrow evening. Tuesday will likely see the higher spots remaining in the 30's for high temperatures. We will moderate a bit by Wednesday but temperatures for the rest of the week will remain well below normal for mid-November with highs struggling to escape the 40's through the week.
