Increasing clouds red sky east losing the sun. 25f humidity 52% dewpoint 10f wind NNE 12 mph expecting 1.1” of snow followed by sleet 0.4 then freezing rain 0.1. Those are my expectations.

Cloudy 36f dew point 25f going up to 50 under sunny skies forecast I saw this morning. Ummm I don’t think so looks like warmth is being shooed away.

Actually wait maybe the Nam is trying to take a weak primary low to near Pittsburgh and then transfer its energy to a new low near the coast and develop and slow down / blocked.

Guessing storm slows moving in the eastbound and a piece drops down from the North / North-northeast.

Well I see Chester and Delaware counties and Southwestern New Jersey are getting coal for Christmas no Winter Storm Watch here lol. This goes right along with my thinking earlier Winter Weather Advisory SE Pennsylvania and Winter Storm watches north and northeast. The more important snow line I-76 points northwest, north, and northeast.

That’s going to be solid warmth streaming in out of the west-southwest aloft east-northeast at the surface gotta keep that NE flow CAD for this one or game over in regards to pure snow.

As I see it now my inkling is that the block is too far east and like most times over past few years the cold air is booted NE and outta of southeastern Pennsylvania. I think our true potential down here in southeastern Pennsylvania is 1-3” of snow then flip to sleet / freezing rain. This is kind of a repeat from yesterday just more energy and moisture to work with. It’s clear favored areas are NE Pennsylvania as far south as Doylestown points east and northeast from there. 4-7” Doylestown points NE. I would go winter weather advisories southeastern Pennsylvania western New Jersey and winter storm watches northern Montgomery County Bucks County points NE. Subject to change but best guess right now. it would take a fairly strong block to keep the torch of airmass in the central and western United States from advancing east bound.

So, 3-5" of sleet then freezing rain Let's Go!!

1.2” in Media all roads covered for a time While snowing 34 start dropped to 31 then back to 33 when it tapered.

Hmm how about that 12z gfs

Actually, more snow East, North, Northeast the warm air is punching in from the west southwest.

Umm hmm ?? Kind of out there in a tight window we shall see?

Yea White Christmas is essentially dead outside of Kamu’s lingering snow pile. I could see some localized street flooding and stream rises from the next system Thursday into Friday. 11 degrees this morning in Media. Currently 22f with a 12f dewpoint identical numbers from 24 hours ago. Snowpack doing its refrigerator thing.

I think what he means is a northwesterly flow turning more west-northwesterly aloft with winds turning southwesterly and overriding the cold air at the surface. Oh, and we are on the far southwestern edge of the cold air that is slowly being eroded from the west in time.

Mood flakes have arrived here in Media with a slight dusting on all surfaces. Officially a trace today 22f humidity 75% 16f All snow showers moving NW to SE across the area.
