Still snowing in DelMarVa.  Convoluted Miller B situation where transfer happens with dry slot then CCB from coastal for Southers PA and MA.

Well, that at least gets my area to 3-6 which I'll take. Of course it all comes down to mother nature herself what actually happens, regardless of what the models show.

CTP isn’t buying anything! Snow Showers

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
In the extended, all attention remains on model details
associated with storms system tracking towards the mid Atlantic
coast Sunday night and Monday. Model consensus showed a slight
northward jog in QPF/snowfall overnight, only to return farther
south with a flatter wave solution with 12z runs this (Fri)
morning. Negative NAO/Positive PNA pattern means we`ll have to
keep watching closely for the evolution, although upstream
blocking high is absent which should act to favor the flatter
wave and southern solution, keeping heaviest snowfall along and
south of the Mason Dixon line. Still, this track will bring
plowable snowfall to at least the southern third to maybe half
of central PA beginning late Sunday night and continuing Monday,
with many more details still yet to be determined heading into
the weekend. Very preliminary ballpark ideas are that a coating
to 2" could be in play across the central mountains, with 3-5
inches or more possible along the southern tier.

In snowier solutions that only comprise 25% of members, the
wave packet is more amplified allowing moisture to advect
farther northward and jet forcing to be stronger. This could
force the heaviest snow axis to land within our CWA, but again
a flatter wave solution is favored at this time due to
aforementioned factors.

PoPs remain high and all snow Sunday night into early Monday,
with snow likely winding down through the latter half of Monday.
The storm is not fully within the 72-hour range of
deterministic QPF and snow forecasts.

Behind the departing storm system Tue-Thu, lake effect and
upslope snow is expected in NWerly flow. Temperatures will run
5-10 degrees below average Mon-Wed, and may bottom out at 10-15
degrees below average for Thursday

 I already sent him that but guess it did not convince.

Come on Bubs you and I have been in this game for forever! I want WSW now! :D

I was just letting you know that the 'snow showers' was an AI or automated thing and the NWS blokes were not on the same page.   Zone forecasts are not something to back all your chips with!

GFS is going to hold in some sense.   Williamsport Atomix will like.   MA will not. 

The morning of the storm I get up and deal with whatever amount of snow I have.

I don’t worry about myself to much, If some of us get a nice storm out of this Great!!
