...Rains expected for the major cities in the Northeast with heavy snow
possible in the mountains...

...Another day of record-breaking warmth along with Red Flag Warnings for
portions Southern California on Saturday...

...Potentially damaging winds expected across portions of Northern and
Central California beginning Sunday night...

Expect a quieter weekend ahead across the northern Plains and Upper
Midwest, as the powerful system that brought strong, gusty winds and
blizzard conditions to portions of the region continues to gradually
weaken and shift east.  However, a series of disturbances moving around
the upper low will likely produce periods of snow from the Great Lakes
into the Ohio and Tennessee valleys and central Appalachians on Saturday. 
While widespread heavy accumulations are not expected, these snow showers
may become locally intense -- resulting in reduced visibilities and
hazardous driving conditions.

Farther to the east, low pressure will continue to develop along the
system's leading cold front.  This will support areas of heavy rain and
snow as it moves into the Northeast on Saturday.  While mostly rain is
expected along the coast, including the major metropolitan areas, heavy
snow accumulations are possible for the Adirondacks, as well as the
mountains of northern New England.

In the West, dry and unseasonably warm conditions are expected to continue
across much of California, Nevada and Arizona through the weekend. 
Another day of record-setting temperatures is forecast for Saturday across
portions of Southern California.  The warm and dry conditions, along with
gusty winds continue to prompt Red Flag Warnings for parts of Southern
California as well.  A High Wind Watch is in effect for portions of
Northern and Central California. A front dropping through the state is
expected to bring potentially damaging winds into the region beginning
Sunday night and continuing into Tuesday.
