There’s been a varying signal for some system to move into New England around Christmas for several days. The signal is better defined inside 84 hours now, with a clipper now likely to cross the region Christmas Eve rather than Christmas.
The trend has been a slightly sharper system, with the possibility of region wide light snow. The best qpf looks focused in CNE and NNE.
With an excellent antecedent airmass (Euro colder than GFS) and a little moisture, many could see measurable snow right before the Christmas holiday. Perhaps enough for an official white Christmas.
Discuss.
