My dad used to say the same things to me about the 1940's and 1950's growing up in Philly. Then I showed him the data. We all believe it was snowier and colder when we were kids. This is why we have facts to keep it real...not discounting memories. I have mentioned this before but from 1967 to 1978 Philly had no significant snows over 6" at all! Imagine if that occurred today the kids who grew up in our snowy climate since 2000 would be crying daily....kind of like they are now. LOL!!

Well if you only go back to 2020 for sure....but 2010-2019 was snowier than the 70's / 80's / 90's....would you believe the 1970's were the least snowy decade?? I do because it never snowed in the 1970's in Philly!

I grew up in those years and we never saw much snow from 1967-1978 PHL recorded not one storm over 6". The snowiest decade of most of our live was the last complete decade from 2010-2019. The facts show it in fact did not snow more back when Steve was a kid and we followed Jim O Brien and Herb Clarke....it snowed more when we were adults in the last 20 years - 2 of our snowiest decades on record. Amazing how facts often fail to support our feelings! LOL!

Yes - let me know which stations/years you want and your email address and I will send it along.

I had looked at snow data for your area a couple years back and I think you are not too far up the road from here and it looks like at least at Blue Marsh Lake (is that close to you?) snow totals have trended higher in the last 46 years

I suspect our last complete decade in Western Berks was one of the snowiest on record....nothing has changed just cycles. Like I said above imagine going 23 years with below normal snowfall like Chesco did from the 1930's to 1950's....

Sometimes this hobby requires such huffing.....

12z Ensembles - White Christmas Season incoming - keep the faith Team Snow!! I will keep finding the snowiest maps!

Truth!! as a NWS spotter I have to add them up and report each one. Most folks will say it didn't snow at all....heck I have 3 winter "events" and all it totals is 1.1"

I have seen a lot of chatter across social media on how it doesn’t snow as much as it used to and if we don’t see significant snow by the end of December it is winter snow potential over! I have framed up some stats on some recent winters that may be why some of these folks may being influenced by some recency bias based on winters here during the past 20 years. Keep in mind it is only December 7th and some spots including East Nantmeal in Chester County have already exceeded 1 inch of snow for the season – to date most spots in our area average near 2 inches of snow to today's date in a typical season. Assuming we see no more snow this month below are some snow stats for years with 1 inch or less of accumulated snow by New Year’s Eve and the final seasonal snow totals. There is for certain a correlation but enough outliers to allow for Team Snow folks to dream! 30 years with 1” or less of snow by December 31st · 5 seasons ended up with above normal snowfall at +35” · 8 seasons ended up between 60% to 85% of normal snowfall at +20” · 7 seasons ended up between10” to 15” of snow · 6 seasons ended with no snow to 10% · The greatest snow season with little pre 12/31 snow was 1977-78 when 59.8” of snow fell · The least amount of seasonal snow was 1972-1973 when no snow at all accumulated that season at Coatesville. To put the above in greater perspective at the NWS and trained spotter locations at Coatesville 1W/2SW and East Nantmeal there have been 47 winters with greater than 35 inches of snow. In 3 decades 1900-1909 / 1910-1919 and just recently in 2010-2019 we experienced 6 winters seasons with snowfall greater than 35”. The longest stretch of no season with over 35” was the 23 straight snow seasons from 1934-35 through 1956-57 that all failed to exceed 35 inches of snow for the winter season. So far here in the 2020’s only 2020-2021 with 52.2” of snow has exceeded the 35” mark. So, if you think it doesn’t snow as much as it used to…just imagine growing up in Chester County in the 1930’s thru 1950’s! It is important to remember our last complete decade from 2010-2019 was our 3rd snowiest decade since the 1890’s with only the 1890’s and 1900-1910 averaging more snow then that last decade we just completed. If you are a believer in cyclical climate change like me I would suspect we are due for some less snowy winters.

While still colder than normal for early December it will still be about the best day this week to start or finish (in my case) putting up your Christmas decorations. Highs today will be well into the 30's but still at least 5 degrees below average. We again turn sharply colder tomorrow with the passage of an arctic front late tonight. Temperatures both tomorrow and Tuesday will remain below freezing. Tomorrow night looks to be our coldest night so far this early winter season with low temperatures not too far from 10 degrees. We moderate to closer to normal on Wednesday with rain shower chances increasing and then by Thursday night into Friday may see chances for some snow in at least parts of the area. We again turn very cold by next weekend.

Across Chester County the AM rain turned to Christmas PM snow with as 2" to 6" across the area depending on elevation.

Our 4th potential winter event of the season could arrive by Thursday night. Models are starting to show this possibility. With the European currently the least enthused with the potential.

Most locations reported some measurable snow overnight with 0.3" of snow here in East Nantmeal. This is our 3rd winter event of the young winter season. Of note yesterday was the coldest early season day in the 23 years I have lived here in East Nantmeal. In addition to the record low maximum (25.7) we also recorded a record low for the date (19.7). Our unseasonably cold start to December will continue for at least the next week. With some of the longer-term guidance indicating we will continue to see below normal temperatures right through the entire Christmas Holiday Season. We turn a bit milder over the weekend with highs both today and tomorrow well into the 30's but still several degrees below normal for the date. We turn sharply colder again on Monday and Tuesday with highs both days struggling to get to freezing. Our next rain chance is Wednesday afternoon and the next light snow chance on Thursday night.

Top 3 coldest December 5th in 133 years.....even with the rumoured "warming climate" this of course still happens

It has just started to snow again here in East Nantmeal for the 1st time since earlier this morning. Temp is 24.7 degrees

Quite a few stations across Chester County have remained in the 25 to 27 degree range for maximum temperatures so far today. If temperatures don't rise much more before midnight today will finish in the Top 3 coldest December 5th daytime highs since records began in 1893. So far here in East Nantmeal our high has been 25.7 degrees we are currently at 25.4 degrees. Below are the top 5 lowest max temperature days.

In an effort to keep hope alive for those on Team Snow - Another view from a "well respected" Meteorologist "The Southern Oscillation Index (SOI) is a key indicator of the strength and phase of the El Niño–Southern Oscillation (ENSO). Sustained strongly positive SOI values (typically 30-day average > +7 or +8) are associated with La Niña conditions, and sustained strongly negative values with El Niño. This graph shows a very sharp collapse of the SOI from strongly positive (La Niña-like) values around +18 in mid-to-late November 2025 down to slightly positive or near-neutral values by early December 2025. “This is one of the fastest SOI drops on record.” After a sudden SOI plunge of this magnitude and speed, the most common lag time to the first big Eastern U.S. winter storm or polar vortex disruption-driven cold wave is about 2–3 weeks, with a broader 10–35-day window of elevated risk. So for the drop shown in this image (finalized ~5 Dec 2025), the highest winter storm threat in the Eastern US is roughly December 18 – January 10, peaking late December to very early January 2026. So Christmas could be extremely Wintery this year! ~Meteorologist Mark Margavage"

Here in Chescoland stuck on Winter event #2 - only saw 8 flakes today! However, website updates are continuing with some new content coming out this evening! stay tuned!! Everything you ever cared to know about Chester County Climate. I actually have the data set in excel, google sheets, looker studio and of course backed up to an external drive!! So Birds is not too far off!! LOL!!

Some great insight on the attached link below focused on the decline of climate alarmism and a move toward climate realism - enjoy! https://wattsupwiththat.com/2025/12/05/live-at-1-pm-et-good-news-climate-cult-in-decline-the-climate-realism-show-184/

Wow! forgot about Ruggie! Whatever happened to him?
