...Coastal storm will continue to impact the southern to central
Mid-Atlantic states on Friday...
...Another shot of arctic air expected behind a cold front dropping out of
the north central U.S. on Friday...
A surface low will continue to deepen while it steadily tracks up the
Carolina coast on Friday. Plenty of Atlantic moisture getting wrapped
into the storm will fuel widespread precipitation across the southern and
central Mid-Atlantic states. The majority of precipitation will fall as
rain...but enough cold air initially in place will allow for a mix of snow
and freezing rain within the northwestern fringe of the precipitation
shield. The intensifying coastal low will begin to track away from the
coast and out into Atlantic Friday evening...and locations across the
northern Mid-Atlantic region and Northeast should see minimal impacts from
A strong surface high sinking down from western Canada will bring yet
another shot of arctic air into the north central U.S. on Friday. Snow
showers will be possible with the leading cold front as it pushes from the
Upper Midwest to the Lower Great Lakes...but a lack of moisture along the
boundary should keep precipitation light.
Energy amplifying aloft combined with upslope flow will force moderate
snows across the Central Rockies Friday into Saturday morning. As some of
the energy ejects eastward on Saturday...light precipitation should begin
breaking out across the Southern to Central Plains.
The Pacific Northwest will get a break from the recent widespread shower
activity across the region as an upper ridge builds in aloft on Friday.
However...an approaching Pacific storm should bring precipitation back
into the northwestern corner of the Nation by late Saturday.
