...A nor'easter will develop Wednesday, spreading snow to the northern
Mid-Atlantic and Northeast...
...A low will bring rain and mountain snow to the western U.S. by
Thursday...
A nor'easter is expected to develop from a surface low currently located
in the southeastern U.S. The surface low will make its way just offshore
of North Carolina, the Delmarva Peninsula, and across Cape Cod late
Wednesday night. To the north and west of this low, snow is expected for
the northern Mid-Atlantic and Northeast. Snowfall totals are forecast to
be over a foot for portions of the Northeast west of Interstate 95 through
Thursday evening. 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 www.weather.gov, and our snowfall probabilities to

Farther west, a surface low will linger over the Great Lakes region,
producing more snow in that area. Snow totals are forecast to be 6 to 8
inches for the Upper Great Lakes through Thursday evening. And farther
south, a cold front will push through the Southeast and Florida, and
showers and thunderstorms will continue ahead of it Tuesday night. A few
storms could be strong in western Florida.
The western U.S. is expected to remain generally dry on Tuesday night and
into Wednesday. By Wednesday evening into Thursday, a low will approach,
spreading rain and mountain snow into northern California and the Pacific
Northwest on Wednesday evening and into the Northern Rockies on Thursday.
Rain and snow totals will be fairly light for this system through
Thursday.
