Can see Nam looks more like euro here What I really see here is the major divergence more so would come between the 84-108 window of time…none of these are that much different from a NA500 hemispheric perspective.

I'll wait for the 18z suite but I'm thinking probably 4-8 for now? I want to suggest significant accumulation but keep a lid on it for now. I did this 20+ years ago and always hyped it up too much. Was great when the jackpot hit though. “4-8 or 6-8 inches and possibly more, and we will know much more at the end of the week” seems fine 1 Link to comment Share on other sites More sharing options...

Take a look at it in motion. The Nam at 84 is starting to phase energy and starts to turn east while the gfs continues to dig se. Link to comment Share on other sites More sharing options...
DDweatherman Posted January 20 Share Posted January 20 Time for the real 18z models..and a Prozac. Main focus is efficient release of the Baja s/w and no further slowing of that and timeline on arrival of precip. 1 3 Link to comment Share on other sites More sharing options...

mattie g Posted January 20 Share Posted January 20 Looks like the upper energy gets out in front a little bit on the ICON, so it doesn't wrap up as much. Link to comment Share on other sites More sharing options...

DDweatherman Posted January 20 Share Posted January 20 Some of the models have shown the n/s getting a little quick, which wouldn’t kill the storm quite like the Baja s/w getting buried, but it would reduce the probability of long duration precipitation and some Of the high end upside.

StormyClearweather Posted January 20 Share Posted January 20 I mean it's noise, but it's a little better verbatim, though I wonder if this is more just it being a little faster than anything. 3 1 Link to comment Share on other sites More sharing options...

Eskimo Joe Posted January 20 Share Posted January 20 For our lower Delmarva / southern MD / VA tidewater folks. Only two 12z Euro AI EPS members have below 10" of snow for Virginia Beach. What an incredibly consistent signal at this range, which is right in the Euro AI EPS's wheelhouse. 6 1 1 1 1 Link to comment Share on other sites More sharing options...

poprock49 Posted January 20 Share Posted January 20 Hey all, I'm here to add to the barrage of teenagers (HS, I'm roughly between @bncho and @Nomz). Been heavily lurking for about a year but I'm so hyped for this storm I finally decided to post. My APUSH teacher had some sage advice for my class today that I'll share here: "don't get too excited, the energy warms up the atmosphere." lol. Let's reel this one in! 13 1 6 1 2 Link to comment Share on other sites More sharing options...
Eskimo Joe Posted January 20 Share Posted January 20 Today we start to cross the HR120 (D5) threshold. Should see the guidance really tighten up over the next 24 hours. Would caution folks here that might result in some extreme solutions getting eliminated and thus, reducing a mean snowfall here or there. That does not mean this is "trending towards a bust", but rather just narrowing towards a better forecast. 10 1 Link to comment Share on other sites More sharing options...
