...Strong storm system will affect New England on Sunday...

...Scattered rain and snow showers likely from the Central Rockies to the
High Plains...

...Cold front to bring cooler weather to much of the Plains by Sunday...

The strong East Coast storm system that has produced coastal flooding and
heavy rainfall over the past couple of days will affect New England
through Sunday as the main surface low lifts northward to eastern Canada. 
New Hampshire and Maine will be the recipients of the heaviest rain
through Halloween with 2 to 3 inches of rain possible, particularly across
southern Maine where the moisture flux from the Atlantic will be most
concentrated.  A Slight Risk for excessive rainfall is also in effect for
this region, and some instances of flooding will be possible in addition
to coastal flooding.  Conditions should quickly improve in time for the
beginning of the work week with some lingering showers possible, including
some lake effect showers downwind of the Great Lakes and snow showers for
the highest elevations.

To the west, a cold front will continue to move southward through the
Plains while stalling across the Rockies and Great Basin.  Scattered rain
and snow showers will develop across the Central Rockies and High Plains
throughout the day Sunday as the cold front continues slowly southward. 
Any snow accumulations are expected to generally remain light with this
system given the relative dearth of moisture available.  Colder
temperatures will spread southward on Sunday, with highs in the 40s for
the Northern Plains, 50s for the Central Plains, and lower to middle 60s
reaching portions of the Southern Plains.  Elsewhere, generally dry and
seasonable conditions are expected for most of the Southwestern U.S.,
stretching east across southern Texas.  Some showers are possible across
coastal portions of the Florida Peninsula, but should remain light.  A
storm system over the eastern Pacific will approach the coast of the
Pacific Northwest and northern California by Monday morning with
increasing rain chances with up to an inch of rainfall possible.
