Monday-Tuesday...
The Pacific system arrives in the Eastern USA, generating a coastal
storm along the Carolina coast. GFS is faster, the ECMWF is slower.
Both bring plenty of precip to Srn New England, just a little
different on timing. As with the Sunday skies, and based on the
stronger amplitude aloft, we favored a stronger blend of the NBM
with slower guidance. Both camps of models bring roughly 1-2 inches
of water to the region, with snow over interior sections while the
coastal plain converts to rain Monday afternoon...then mixes with
snow Monday night and Tuesday. Interesting to see IVT guidance
clearly showing the moisture feeding in from an atmospheric river
from the southern Gulf of Mexico and waters east of Florida.
