.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
The coastal low bombs out near New England Tuesday spreading a
generous amount of snow to it's west under the diving upper
trough. Snow production will be further enhanced by favorable
upper jet support. Despite the uncertainty addressed in the near
term above, interaction between the tightening baroclinic zone
over the region and the strengthening coastal low may still
support a deformation back of snow that could support higher
snow totals outside of the ridges. This is supported by the
newest GFS and NAM despite the cut in snow totals.
Bulk of the heaviest snow should be done just after sunrise on
Tuesday with snow showers continuing in north-northwest flow on
the backside of the departing coastal as it moves into New
England. Strong cold advection and the pivoting upper trough
will support further accumulation through the day Tuesday and
Tuesday night, with upslope enhancement supporting a
continuation in headlines through Wednesday morning. Even if
snow amounts in the lowlands remain light by Tuesday morning,
northwest flow should support the current advisories.
