Happy Valentine's day: will it snow over the weekend?

Happy Valentine's Day to all! After following the NWP models nearly daily for the past 2+ months, we finally have a couple of solutions that indicate a potential for a snowstorm over the weekend. Will be worth following over the next couple of days- to see whether the major upper-troposphere players (various amplitude shortwave troughs in the north and south) phase together to promote surface cyclogenesis that moves up the coast, or whether they stay separate and result in a weak low that moves essentially east into the Bahamas. Here's a forecast of MSLP, 6-hr precip, and 850-hPa temp from the GFS.
