...Multiple storm systems to cause wet and snowy conditions across
the Pacific Northwest & northern Rockies...

...Scattered snow showers to stick around in northern and central
Appalachians, Great Lakes...

...A pair of low pressure systems will bring showers and
thunderstorms to the South...

The Northwest U.S. will brace for several rounds of storms over
the next few days. Coastal ranges and valleys of the Pacific
Northwest will witness periods of rain day after day with rainfall
amounts averaging 1 to 2 inches. The higher elevations of the
region's coastal front could see rainfall totals in excess of 3
inches through Tuesday. In the Cascades of Washington and Oregon,
snow will pile up quickly with snow amounts being measured in feet
in the higher elevations. Pacific moisture associated with these
storms will spill east into the northern Rockies where valley
showers and mountain snow is also a good bet through Tuesday.

As the weekend storm system in the East tracks through Maine on
Sunday, snow showers and lake effect snow bands will stick around
across the Great Lakes, eastern Ohio Valley, and the central and
northern Appalachians through Tuesday. The heaviest snowfall will
be located downwind of Lakes Erie and Ontario where cumulative
amounts through Tuesday will range between 6 to 12 inches.
Downeast Maine will see locally heavy rainfall early Sunday
morning but drier conditions will quickly move in before midday,
although a few spotty rain or snow showers across central New
England cannot be ruled out.

Down south, a surface low pressure system will be responsible for
the development of scattered showers and thunderstorms from east
Texas and the Lower Mississippi Valley this morning, then across
the central Gulf Coast by this afternoon. While the thunderstorm
threat should diminish tonight, passing showers will continue
across the Deep South tonight and eventually reach the Southeast
by Monday. The best chance for thunderstorm activity on Monday
will reside across central and southern Florida. Some of the
southern Appalachians could even see a wintry mix develop Monday
morning. By Tuesday, an upper level disturbance in the Southwest
will spawn a new storm system in the southern Plains leading to
another round of showers and thunderstorms across the South
Central region.
