There is no reputable model that is a total whiff or mostly rain. Even the “disaster” GFS is 3-6” WAA/dry slot or rain to snow showers on the back-end.
Yes, this is not locked in by any means to a solution but its hard to argue against the consistency of the EPS.
I do the same at Deep Creek....when I was there for MLK weekend, at one point I just laid down and looked up at the sky as the snow fell on me. I probably have a problem. Lol
The para almost takes the low to Chicago before it hits a brick wall and heads to OH. Basically transfers at our latitude.
4-6" from the thump, dry slot, then 1-3" from snow showers on Monday from the ULL
ICON has snow breaking out across the SW part of the forum ~1a and DC by about 4a Sunday. Transfer is down over/near OBX but primary hangs on longer than I want. I don't really know how good ICON thermals are but verbatim it's all snow in DC through Sunday night (~0.5" QPF has already fallen). The coastal basically zig zags a bit as it heads north from OBX to Lewes.
I like seeing the south transfer on the ICON.
To my weenie eyes, one of the key differences is the strength of the vort as it crosses the country. Euro holds/strengthens as it nears our area which combined with a coastal transfer near OBX + backside energy to capture/slow it down. GFS is initially closed off over the Midwest but then just opens/shears as it heads east. GFS then transfers too far north/pops a coastal low at/north our latitude and the backside UL low swings through and closes off with the SLP too far offshore/north of our latitude.
Euro control is a great hit too. Coastal forms over Nags Head to just east of ORF, stalls for a bit, and heads ENE from there. CCB cranks over the area.
