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.

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??
