...Light to moderate snow likely from the Central Rockies to the High
Plains...

...Cold front to bring cooler weather to much of the Plains and Midwest
for early in the week...

A much quieter weather pattern will be returning to much of the nation in
the wake of the strong East Coast storm system, which is now departing New
England as of Sunday evening.  However, breezy to windy conditions will
still be likely across the Northeast through tonight before abating later
on Monday.  Broad cyclonic flow across the Great Lakes along with cold air
advection is expected to result in lake effect rain and snow downwind of
lakes Superior, Erie, and Ontario, with snow most likely for the higher
terrain downwind of the lakes.  Snow is also expected from the central
Rockies to western Nebraska as a modest disturbance aloft moves across
this region where winter weather advisories are in effect and a few inches
of accumulation will be possible.  Some showers are possible across
coastal portions of the Florida Peninsula, but should remain light. 

For the West Coast region, a storm system over the eastern Pacific will
approach the coast of the Pacific Northwest and northern California by
Monday morning.  Portions of northwestern California and southwest may get
on the order of 1 to 2 inches of rainfall, but should avoid any noteworthy
flooding concerns.  Snow is expected only for the highest elevations of
the northern Sierra given the warmer temperatures associated with this
front that should weaken shortly after moving inland. 

In terms of temperatures, it will be rather chilly across much of the
central/northern Plains and extending eastward across the Ohio Valley and
Great Lakes for the beginning of the week.  Highs will only be in the 30s
and 40s for many of these areas, and widespread subfreezing overnight lows
expected.  Seasonably warm conditions can still be expected for the Desert
Southwest, Texas, and the Gulf Coast region.
