...A nor'easter will spread snow to the northern Mid-Atlantic and
Northeast...
...A low will bring rain and mountain snow to the western U.S. by
Thursday...
A surface low pressure and associated frontal system is quickly
transitioning into to a nor'easter and will spread snow to much of the
northern Mid-Atlantic and Northeast today through the end of the week.
Numerous Winter Storm Warnings and Winter Weather Advisories are in effect
across portions of the northern Mid-Atlantic and the Northeast. The storm
is expected to track offshore the Del-Mar-Va peninsula northward while
paralleling the Northeast Coast. By Thursday evening, snow accumulations
could easily surpass 1 foot fore areas west of the I-95 corridor. The
major cities will be on the gradient in between the substantial snowfall
totals and light snowfall totals, so there is uncertainty in how much snow
will fall in areas such as New York City. See your local forecast on

Snow will persist over the Great Lakes region over the next couple of days
as low pressure hangs around - with an additional 6 to 8 inches possible.
For the Southeast, showers and thunderstorms are expected for portions of
central and southern Florida today as the cold front pushes south.
Across the West, conditions will generally be dry through this afternoon
before a low approaches the coast. Rain and mountain snow will spread
into northern California and the Pacific Northwest this evening and into
the Northern Rockies on Thursday. Rain and snow totals will be fairly
light for this system through Thursday.
