3knam at 500 looks like an overall better trough alignment to me . Lakes low is slightly further west this run allowing hieght rises to the east ne.

Both nams shifted the polar low in Quebec west. WIll parobably only be a factor for New England.

Nams remind me of the euro with the shield to the west of the low. Not identical of course but they both have the same bulge to the west. 

It's doing the same thing, messy reorganization of the precip as the northern stream system temporarily interferes and kicks it east. Only it's doing it right at our latitude screwing our eastern zones instead of NYC to Boston.

Bottom of the trough at 42 on the 0z 3km nam looks horrible compared to the same time on the 18z.

I actually thought the 18z 3k was slightly worse then 12z. 12z just didn't go out far enough but it might have nukes us had it. It's been a slight degradation both runs since. At 60 12z was slightly better then 54 on 18z. But I didn't want to ruin the party saying that.

Rgem would get precip to dc. How much us debatable but it certainly looks on its way to pushing that western bulge west of the bay. Delmarva would do well

Looks like 10 mm through DC

GFS hanging back the southern shortwave more.  Typical GFS. Seeing as it's 66hrs out, I'm going to say it's still not hanging it back  enough.

Gets zero precip into VA excluding far southeastern VA and flurries for the Delmarva

If this thing is coming west the GFS isn't going to catch on until 18z or 0z tomorrow. It shouldn't be a surprise to anyone whod been through this drill.

I just compared the gfs at 60 to the euro at 72. Low strength and placement is very similar. Gfs is only a little east with low. I think the only thing the gfs is missing is the western bulge. Something going on there across guidance with the gfs being odd man out on that.

Solidifies the trend east for the night. Models are almost unanimous with an easterly shift. 

And so far pretty similar in low placement as well. No double barrel lows or tucked in lows. Just way out in the Atlantic lows.

If anything we are probably seeing a correction to more of a GFS solution like Bob Chill said would happen tonight...

Still 24-48 hrs until game-time and we don't know exactly how the interaction at h5 will go tomorrow night and Wednesday. But I think it's safe to say that the westerly trends today have stopped dead in their tracks.
