the gfs is still in the "room for surprise" zone. not sure the surprise would be amazing but..

I'm glad you posted this. At least it means I can see something. It looks like that feature is getting better. I expected a little better surface result, but it isn't much different. But, who knows? I do know this. The past two marginal temp events here have both been modeled too warm, at least during the precip stages.

Thats the upper level low vort thats trying to give us that precip right?

yes. it has still been shifting south slightly on the gfs overall. on the max passes just south of d.c. it seems. at this rate it's not making it where we need it but it could still prove to bring some snow.

Yeah, I forget, is the EURO more like the NAM or GFS with this? Because I know the NAM looks further north with it...doesnt give us much of anything

Well I think Wes made some points not in it's favor and it is marginal at best. At this pt if I were in elevation NW of the cities I might be slightly hopeful for whitened ground. This vort looks a good bit better than it did in addition to being a bit south.

new gfs run is looking a lot better. Slower and further south with the vort.

Problem is still the fact it runs the 500 trough and energy right through MD. Northern MD around the Mason Dixon line would have a shot with that set up for maybe a few inches. Think the rest of the area would be lucky to see more then just a change over to flurries with what the GFS is showing.

12Z NAM looks ugly for any snow chances. Shifted the 500 energy north and now goes through N MD and SE PA.

And it's getting into the time range where it usually isn't that bad. The vort needs to go south of us enuf to get us in the deformation zone and that doesn't looks like it is likely. Barring that we dry slot.
