...Developing winter storm will impact much of the Northeast on
...Showers and thunderstorms will be possible along the central Gulf Coast
A wide axis of precipitation will continue to develop to the north of a
cold front sinking south and east through the Central
Plains...Midwest...and Ohio Valley on Tuesday. Falling temperatures
behind the boundary will allow for snow within the northern edge of the
precipitation shield...resulting in a swath of accumulations stretching
from Iowa to the Lower Great Lakes. On Wednesday...a surface low along
the front will quickly deepen while it tracks from Ohio Valley to the New
England Coast...and the brunt of the action will shift focus to the
eastern third of the Nation. Increasing amounts of moisture getting
pulled out of the Gulf and Atlantic will help set up a wide zone of
moderate to heavy snows to the northwest of the developing surface low.
Widespread accumulations are expected from the Lower Great Lakes into the
Northeast...with snowfall totals possibly approaching or exceeding a foot
across interior New England. Also...warmer Atlantic air moving in aloft
should allow for a narrow axis of freezing rain closer to the coast.
Elsewhere across the Nation...showers and thunderstorms will continue to
develop beneath a piece of southern stream energy crossing the Central
Gulf Coast states and then lifting northeastward through the Southeast.
Strong surface high pressure sprawling out over the Rockies will keep
locations west of the Continental Divide precipitation free through the
middle of the work wee.
