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.

I never look at PHL anymore just too much UHI problems....Just typical cyclical climate change....warm - cold - warm - cold rinse and repeat

In our current "warming climate" 3 of the last 4 months have been below normal.....

Does anyone follow JB any more?

For those on Team Snow or at least Team Cold the below from meteorologist Steve Dimartino should make you happy. "The Ensemble guidance today is showing the weather pattern I've been talking about since September. I think interesting times are ahead. What that means for your backyard snowfall, I don't know. However, I do know that this is one of the most favorable weather patterns I've ever experienced in December in a decade."

As we always try and present any and all models that produce any measurable snow.....we do have the 18z NAM with a move north of accumulating though minor snow tomorrow PM.

An arctic front moves through later today with maybe a couple snow flurries. We turn windy and cold behind the front with highs today in the mid-30's and lows tonight will be near records levels for some stations with shorter periods of record with lows by tomorrow morning in the mid-teens. We remain in the upper 20's for highs tomorrow with a chance especially across Southern Chester County for some light snow or flurries during the afternoon. While still well below normal we do warm back up to the upper 30's for the weekend before the coldest weather of the season arrives on Monday. No significant storms over the next week.

Experience has taught me to always take the cold and worry later about whether some clipper or storm will dig and deliver to the Northeast/ Northern Mid-Atlantic....if no cold no snow! Keep the faith folks!!

Our well below normal temperature pattern for December looks to continue for much of the next couple of weeks. Tomorrow night and Friday look to be our coldest temperatures so far this young winter season. By Friday morning, the lows will be in the low to mid-teens with highs on Friday remaining below freezing. We will also see multiple chances of some light snow over the next couple of weeks. Our first chance of some measurable snow looks to arrive Friday afternoon into the evening. None of these look significant but if they were to occur they would certainly add to the holiday spirit.

0.78" of liquid melted today in EN

The temperature here finally went above freezing at 1235pm. Of note we still have ice up in the trees but the current temp is 34.6. Need to melt the ice on top of the coco bucket to get final rain amount. Lots of puddles around could see some slippery spots tonight.

Still moderate ZR temp 31.9 here in East Nantmeal

We are now mainly ZR with a few ice pellets mixed in. Ended with 0.3" of snow/IP accumulation. Temp at 30.8 degrees

This morning's wintry mix our 2nd winter event of the season should slowly change to plain rain as we rise above freezing in most spots by later this morning. Some higher ridge spots may take into the early PM to get above freezing. Be careful if out driving this morning. Either way the rain will end later today, and we will stay much colder than normal for the rest of the week. Our warmest day looks to be tomorrow with temperatures near 10 degrees below normal for early December. We turn even colder by Friday with highs remaining below freezing for much of the area. There is a slight chance of some light snow on Friday night.
