Lakes this weekend…
The significant winter storm that brought widespread impacts to much of
the South over the past couple of days will wrap up tonight into Saturday
morning as the associated low pressure system quickly sweeps eastward off
the Mid-Atlantic Coast. Prior to its exit, widespread light to moderate
snow will fall from the Tennessee Valley to the Mid-Atlantic. The highest
snowfall accumulations will be confined to the higher elevations of the
central and southern Appalachians as well as southern Virginia where an
overall 3 to 6 inches (with locally higher amounts) is expected. Lighter
snows will extend northward into the Ohio Valley and parts of the
Northeast which will result in roughly 1 to 3 inches of accumulation. To
the south of the heaviest swath of snow, freezing rain and disruptive
icing will be a concern across portions of the Carolinas, particularly for
the Charlotte and Raleigh metro areas where a tenth to three tenths of an
inch of ice is expected. The widespread footprint of both snow and ice
combined will lead to additional impacts, including dangerous travel
conditions and power outages. Most locations will start to dry out by
Saturday afternoon in the wake of the storm, but temperatures will plummet
by as much as 10 to 20 degrees below normal through the remainder of the
weekend.
A fast-moving Pacific storm has pushed into the Pacific Northwest, which
brought coastal rains and mountain snows to much of Washington and Oregon
this morning and early afternoon. This system will quickly race across the
northern Great Basin and into the northern Plains tonight into Saturday
morning, producing widespread snows as it does so. The most significant
accumulations will occur in the highest elevations of the northern and
central Rockies where accumulations in excess of 1 to 2 feet are likely.
The storm will scoot across the northern Plains and into the Upper Midwest
by Sunday, bringing widespread lighter snows to those regions with a
general 1 to 4 inches of accumulation.
