ChescoWx

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.

Sleet mixed with a few mangled snow flakes here in East Nantmeal in NW Chesco temp 30.8 DP 22.9. With our 2nd winter event of the 2025/26 season. Surfaces have a small snow/sleet cover.

As it shall this time as well!!

For those on Team Snow - I present the latest European AI model ensemble means run....the best weenie run I can find - so you mean there is a chance??

28.2 degrees DP 17.0

The HRRR tries to sneak the 2" line into NW Chesco and close to ABE....for snow weenies we present the snowiest latest models...

I suspect even that 1" up at ABE may be a bit overdone if the latest models are onto something...850's a bit toasty

November finished as our 3rd below average temperature month over the last 4 months. December looks to also be getting off to a well below normal temperature start. Sunny today but with temperatures almost 10 degrees below normal for highs. Clouds roll in tonight with some snow arriving toward dawn. The Winter Weather Advisory starts at 4am for Western Chester County. Any snow to start should quickly change to sleet and then rain with little if any accumulation. That said with the timing near rush area it may be a bit slippery for the morning commute. High temperatures Tuesday through Thursday will be in the mid 30's well below average but fall even further below average by Friday as the coldest air of the season arrives. Temperatures on Friday will stay in the 20's. Another wintry event is possible by Friday night into Saturday.

Of course official NWS measurements are never made on concrete or driveways. A good mailbox or wood deck can work quite well for snow measuring if you don't have a trusty snowboard like some of us weather weenies employ!! LOL!!

Nice map IMHO!! As you mention I suspect an adjustment will be needed tomorrow...a nice 50 mile NW in snow accumulations may well hit the mark! Thanks!!

All that said the ensemble run held serve or even increased amounts a bit.....so you say there is a chance??

All of the models have started to reduce snow totals by at least an inch from the last run....

Following our 0.5” of snow this morning - some light rain will continue into early this afternoon. We clear up tonight and remain chilly with well below normal temperatures for the entire upcoming work week. Our next winter event looks to arrive as snow toward Tuesday morning before a slow transition from snow to rain from southeast to northwest across the area. Some models are showing a plowable event for NW Chesco and into Berks and Lehigh counties. But as we all know we do not shovel model snow. The current NWS early forecast has 2 to 4" possible for NW Chesco to about 1 inch down toward Chadds Ford in SE Chesco. Snow should turn to rain by late morning. We could see more snow arriving on Friday night, so an early season arrival of winter type weather is on the way.

Sorry to hear of your loss. I too have a funeral on Tuesday.

The snow has just about ended and looks to be mixed with drizzle now. The 0.5" of snow we recorded in East Nantmeal this morning will make November 2025 the "snowiest" November since the 7.3" of snow we saw back in November 2018. This is the 10th November in the 22 years I have been at this location that we have received measurable snow during our 11th month. 2025-11-30_9-45-26.mp4
