I think these maps are kind of silly and completely unreliable....I don't know why people use them with any seriousness....I can't imagine a forecast met keeping his job if he used one of these maps to support his forecast

they had us in snow a couple of times already this year even with Sandy. I'm also not a fan.

A lot of mets show them online and stuff. Not completely sure why tho.

Not sure I understand that, but I didn't understand their forecast of rain for me yesterday morning when the forecast the night before was for snow.

Its marginal cold trying to hold against a heck of a warm push. 18Z NAM brings in the precip faster than 12Z did, and if that's accurate we might see a quick 2-3" of snow early. Imagine we sleet pretty hard after that, and when the rain comes we should be close enough to 32 that heavy rates won't accrete well.

Higher elevations might warrant a warning, but it gets confusing if you WSW a whole county for that.

For us close to metro folks it's bleak at best but not a frozen shutout. You can already see with hourly temps the hagerstown and winchester are running 5-10 degrees below folks closer to the beltways.

It's all going to come down to temps at onset. Stating the obvious of course but if you are 30 or below in the early morning hours you can pull off some frozen. Maybe some flakes...or pellets....or even a period of zr but we all know it's going to be a car washer for the most part.

With these marginal temperature setups, I like the NAM forecast soundings at Twister. You can plot for your location. So I set the marker for N-central MD and for mid-afternoon tomorrow after the column is saturated and

the warm nose at 850 is more than just a bit intrusive.

I'm sure I'm doomed except something "interesting" on the front end. Prob not gonna last long at all imby.

The NAM still gives you a few inches before changing over.

I had completely forgotten/given up on this storm but the combination of EURO + GFS is promising, and the NAM is only marginally worse (and still gives us some snow).

DCA will only see a T (or an inch, at best), but I think IAD will record ~4".

Also of note is that NYC will see almost nothing at all, so I'm not sad about missing this storm up there (although I do love living above 40N because the line does indeed seem to be magical). The gradient will be entirely East-West as opposed to N/S.

Have looked over the soundings for 18z. NAM is warmer, GFS is colder for the Shenandoah and Cumberland valleys. The warmer air seems to always come in aloft pretty fast, but the wind at the surface is NNE to almost due north so expect the cold air to remain trapped for a long time. May not get above freezing in many areas.

Freezing rain is the big issue with this, but could get a good thump of snow at the onset.

That's my 2 cents.
