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?

Exactly!! Give me the cold....snow can follow

Steve folks need to get their clicks!! LOL! That said - the many folks who stare at models and post 240 hour snow maps and believe it....or look at 240 hour maps with no snow are both going to be surprised when the opposite ends up the actual weather! We don't shovel model snow and we very well may shovel models that show no snow!!

Some of you might not remember this but December 5th has been one of the snowier days in our December history below are the years it snowed here in Chester County and how much snow we ended up with in that winter season.

Our cyclical climate change is doing it's thing! United States snow cover is now the highest it’s been in 20 years on Dec 5th! The Dec 5th snow coverage is 45.4%. The only higher year on record (since 2003) was 45.7% on December 4, 2005.

Snowing on the beaches in SJ

Our coldest spots were our relatively highest elevation locations with both Glenmoore (19.4) and East Nantmeal (19.7) with lows just below 20 degrees. Unlike on radiational cooling nights where our valley spots are colder...with cold air advection into the area following cold fronts our ridge locales are often colder. This was a record low for today for East Nantmeal with 22 years of records. Some models still try to throw some flurries or light snow as far north as Chester County this afternoon with the coastal low and a little more after midnight with a coastal inverted trough. Either way not much but if it does occur it could cause a slippery spot on to with temperatures remaining in the 20's for high temperatures. We will remain well below normal for at least the next week. Our coldest day after today looks to be Monday with highs again remaining in the 20's. Our next chance of snow or rain will be toward Wednesday night.
