A list of the Top 10 All-time Chester County snowstorms across all locations reported by NWS COOP observers. Some of these no longer report (West Chester and Kennett Square) Glenmoore started in 1956. -
Total rain over the last 2 days was 0.93" with 0.10" falling today since midnight. We have already recorded our high temp for today of 67.1 at midnight. Becoming sunny and breezy today with temps falling back into the 50's by sunset. More showers and much chillier late tonight with temps in the low 40's by Sunday AM. Our temps will now remain well below normal for most of the next couple weeks. There is also a chance of some rain later Tuesday night and I suspect some higher elevation areas in Chester and Berks counties over 600ft ASL could see our first few flakes of the season mixing in with temps in the mid 30's. Our record high for today is 76 way back in 1912. The record low is 15 degrees set back in 1926. The daily rainfall record is 1.40" from 1970. Our daily snow record is 2.8" today back in 1968.

With our 1st possible snow or at least flakes of the season possible over the next couple weeks....I thought I would post the Top 25 Chester County PA snow records for both the total month and individual snowstorms by each winter month. For reference we average 36.0" of snow in a winter season here in the Western suburbs of Philadelphia.

The impacts of Tropical Storm Nicole will move across the area today and tonight....with a cold front then passing the area by very early Saturday morning. We could see between 1" to 2" of rain across Chester County before the front sweeps the rain out to sea tomorrow. Much colder air will build across the area starting tomorrow night with temperatures likely to remain well below normal for most of the time over the next 2 weeks. We may also see our 1st snow chances (at least in the air) on Tuesday night into Wednesday morning. The record high for today is 73 degrees set back in 1949. Our record low was the 19 degrees in 1957. Daily rainfall record is the 2.38" from 1995. The daily snow record is the 4.7" that fell today back in 1987.

About a 10 degree difference in temperatures across Chester County PA this morning over just a couple miles based on elevation. For example here in East Nantmeal at ~700 ft ASL we are at 41.4 while down at lake level at Marsh Creek at ~400 ft they are at 32.0...great example of radiational cooling with relative low spots dropping well below the somewhat higher spots. Temps head back above normal today through Saturday with heavy rain from the tropical storm impacting us starting by Friday AM. Temperatures will then fall to below normal for almost every day through Thanksgiving day which is just 2 weeks from today. The record high for today is 73 degrees set in 1931. Our record low is 16 degrees from 1973. Daily rainfall record is the 2.05" that fell way back in 1898. The daily snowfall record is just 0.1" that fell in 1987 - that was a storm that ended the following day delivering 4.8" of snow to the County.

Suspect this will be a theme of the winter....
-
Thinking any accumulating snow stays pretty far NW of the area through November....but am liking the look of mid-December for our first measurable. That said I do think many N and W of the fall line see some flakes in the air before the end of this month.

A nice couple of normal November days on tap with temps a little below normal today rising to a little above normal tomorrow. Rain moves in on Friday with the remnants of the tropical storm with rain ending by Saturday AM. We could see between a 0.50" to 1.00" of rain. Below normal chill then sets in by Saturday night and should last for much of the next 10 days as we head toward Thanksgiving. The record high for today is 78 degrees from 1975. The record low is 19 degrees from 1976. Our daily rainfall record is 2.04" set back in 1962.

Of note the first 7 days of November were the warmest ever recorded in Chester County PA with records back to 1888. Our average temperature was 61.6 degrees. The previous top 5 warmest were - 2003 (59.9) / 1977 (58.9) / 2015 (58.8) / 1974 (58.1) and 1961 (57.7)

Happy Election Day!! Make sure you get out to vote!! Much cooler today and tomorrow with temps running just a bit below average. Many spots will see freezing temps overnight tonight. Milder but with heavy rain Friday into early Saturday and then the coldest air of the season arrives by Saturday night. The record high for today is 76 degrees in 1975. The record low is 17 degrees set in 1976. Our daily rainfall record is 2.53" from 1996. The daily snowfall record is 0.8" set in 1927.

One last mild day but with temps likely falling this afternoon following this morning's cold frontal passage. The next couple of days following today will see a return to normal temps....but this will feel chilly compared to the last 3 days of 70 degree plus temps. Tuesday and Wednesday will see highs in the mid 50's with lows in the 30's. Friday into Saturday looks like a soaking rain with some tropical storm Nicole influence. Following that it looks like the coldest weather of the fall will set in starting next Saturday night. The record high for today is 75 degrees set in 1938. Our record low is 19 degrees set in 1960. The daily rainfall record is the 1.38" that fell today in 1932.

We set a new record maximum low temperature this AM as we only dropped to 63.2 here in Chester County PA. This breaks the old mark of 62.5 set back in 2015. We will break another record overnight tonight as we should again stay above 60 degrees. The current record for November 7th is the 57 degrees set way back in 1912. We should see temps fall back to near normal during the middle of the upcoming week before a slight rebound to above temps before much colder and below normal weather arrives by next Sunday. I suspect the 2nd half of November will average well below normal temps to balance off much of the early month warmth.

Today's high here in the Philly burbs of Chester County was 75.1. This was the warmest day since September 21st. We only saw one day over 70 degrees during the entire month of October. The record high minimum record for overnight tonight is 62.5 set back in 2015. We may be close to that warm record tonight! Go Phillies!!

This is out 2nd consecutive below normal month and the 5th such month across the first 10 months of 2022. This October is also the chilliest October since 2008.
