Based on a crappy SV EPS snowmap I just saw on Twitter, it keeps tacking on through the end of the run and still ends up with some gaudy totals? But sharper southern gradient then earlier runs.
Several days ago, the storm looked like this multiple series of waves with varying p-types. These MECS solutions consolidated the energy and early in the week. Now we’re back to a bunch of waves along the boundary. Still lots of time left.
Gfs was between 12-18z Monday now. I’d wager that’s a large part of what the EPS is reflecting. Earlier start. Kinda crazy when we started watching this event, it was evening of the 12th into the 13th.
Storm start keeps moving earlier and earlier. GFS has that precursor idea on Monday! 126 hours out. 2nd batch about 24-30 hours later. Euro was about 12 hours slower.
Nor’easter comes from the predominant wind direction, typically during big coastal storms. This storm is forecast to be a bit different (primarily an “overrunning” event), but winds would shift to northeast at the end according to the euro.
