There is quite a dividing line closer to I95. Very classic setup with the NW burbs in it for the long haul.

R u in Trenton today or home in L-town?

Home in ltown today. They closed the state which I was pretty surprised about. Took a drive to Trenton though for my normal breakfast and it wasn't that bad out. Slick in less traveled roads, main highways like route 1 and 13 were just wet though. Starting to mix with a little snow in a lull now though, didn't expect that.

Hrrr last night was showing the warm nose in our area between 6-9am then eroding with cooling taking place aloft after 9am so it actually nailed that aspect. Doing rather well with thermals thus far at least up this way.

29F and moderate snow/sleet mix. Nice beach day.....if you're a Viking or Eskimo :P

Currently 31F and freezing rain here, slept through the changeover so to speak. Did pick up an additional 0.2" after my last measurement at 2 am, which makes the storm total 3.9". Seasonal total is now 14.7", slowly inching towards respectability. Hope everyone up north does well today! Glad I dressed up the snow pile last night (at 2 am), lol.

Awesome! I finished with 4.1". I noticed that the HRRR actually gets us to go back below freezing between 2 and 4 PM. That would be interesting if that happened. It has been nailing temps so far.

Latest hrrr delays 32f surface temps another 2 hours later now for this area til after 7pm. If that trend continues the batch that was supposed to be all rain overnight could theoretically begin as frozen.

ETA: here is extremely close to a minimal change to rain. Even hints that when the convective line blows thru it mixes and isnt plain rain just N of here....possibly signaling rain, pinger mix. Gotta watch temp trends

Some sleet with mostly freezing rain.  Picked up about 0.2 inches of sleet so far. 2.9in storm total.  The sleet only compacted the total snowcover from 2.1in to 1.9in and there is that 0.2 thick layer of ice on top now that will break with about 5 pounds of pressure. 

 The freezing rain is filling in the sleet making a smoother surface, I just wish it would deep freeze now instead of rain.

For far northern zones, precip remains as snow, but the
snow/sleet freezing rain line continues to creep to the north.
Snow totals remain in the 2-4" to 3-5" range for Lehigh Valley,
NW NJ, and southern Poconos. Ice accumulations will be a bigger
threat, with isolated ice amounts of 0.50" or more, but think
up to 0.25" will be the story elsewhere.

Now over to mainly snow here in NW Chester County and almost moderate visibility down quite a bit over last few minutes- a bit surprised as I expected mainly IP and ZR before the change to rain this PM. Temp up to 30.4

Check the hrrr....keeps trending colder and you *barely* switch over for a brief period before system moves out.

Have been fooling around with getting Bufkit up and running again (had it installed on a linux machine a bunch of years ago and finally getting around to getting the latest version on my newer windoze laptop).

It has been switching back and forth between a snow/rain mix and a snow/ip/rain mix here.  There's about 0.1" of slop snow/ip/FZRA coating where the area had been cleared.  Temp just went to 32 so now getting more water on top of whatever coating of ice had accumulated.This almost looks like an old-school clown map.  LOL

   SUMMARY...A wintry precipitation mix will persist into the afternoon
   across the northeast states. Mostly freezing rain is expected from
   central to southeast PA with rates from .03 to locally .1 inch per
   hour. From southern NY to southeast NY and northern NJ, areas of
   moderate to heavy snow should transition to freezing rain toward
   noon or by early afternoon. Farther north from east central NY into
   northern CT, western MA and southern VT, areas of mostly moderate to
   heavy snow are expected.

   DISCUSSION...A large, mature winter storm is in progress over
   portions of the northeast states. Surface low will deepen over MI
   within zone of strong forcing for ascent accompanying a progressive
   shortwave trough. This process will result in a strengthening (60+
   kt) southerly low-level jet shifting northward through PA, NY and
   southern New England later this morning into the afternoon. The
   interaction of the low level jet with the east-west oriented
   baroclinic zone will augment isentropic ascent, promoting a
   continued northeast expansion of the precipitation area. Bands of
   moderate to heavy snow promoted by an increase in frontogenetic
   forcing will develop northeast with time through central and eastern
   NY. While farther south from southern NY, northeast PA into northern
   NJ and southern CT, increasing warm advection along low-level jet
   corridor will contribute to northward advance of the melting layer
   aloft, eventually resulting in a transition from snow to sleet and
   freezing rain. Precipitation should remain freezing rain across
   central and southern PA this morning.
