Looks like extremely light snow or snow showers to my eyes, nothing thread worthy.

For coastal sections this should b watched. The GFS looks better. After yesterday in New England , no reason not to keep an eye out and see if this can

Put down a few inches on the jersey shore onto Long Island

and its still far enough away to trend 50 - 100 miles and include most of the metro

And this is why patience is required in a pattern like this. If ur Gona keep crashing SW s into the coastal plain you will eventually get enough bending when the trough wobbles west u can get deepening close enough to see a trend like this

10 to .25. Not bad for 48 hours out

Wes (usedtobe) in the mid Atlantic thread said he is expecting 20-1 ratios with this clipper! So we could easily see 1-4 inches out of this.

The difference between this system and the previous few clippers is this one has room to develop and there is no other low it is playing off of - and the NAO being slightly negative is slowing things down - so the trends are our friends in this situation - also 0.25 total qpf at 20:1 ratios or greater - well you do the calculations

I'd toss this for now til we see the ensembles, GGEM, Euro, the normally way west NAM at this range is further east than the GFS, although the GFS has not had too many hiccups this year inside 4 days I'd be cautious still.

None of the models have done too well with qpf lately so I'd be very cautious at assuming .15" is going to give 3" of snow. It could easily be half that
