...Heavy precipitation and snow melt contributing to avalanche and
flooding concerns across portions of the Pacific Northwest and northern
Rockies...

...Above normal temperatures will expand eastward into the eastern U.S.
but cold conditions with periods of light snow remain across the northern
tier...

Recent heavy rain and snow, along with warming temperatures and high winds
have prompted Avalanche Warnings for portions of the Washington Cascades
and the northern Idaho and northwestern Montana ranges.  Flood Warning and
Watches are also in effect across portions of Washington and Oregon, where
heavy rain and melting snow are causing excessive runoff and flooding
along some rivers and streams.  Additional heavy precipitation can be
expected across western Washington and northwestern Oregon into the
evening before the focus for heavier precipitation begins to shift farther
south and precipitation rates begin to diminish some overnight.  However,
unsettled weather is forecast to continue across the Pacific Northwest
into the northern Rockies through the middle of the week as a Pacific
system slowly moves onshore.

Father to the south from Central and Southern California to the central
and southern Rockies, dry conditions and above-normal temperatures can be
expected through midweek.

A series of fast-moving systems are expected to bring a wintry mix across
portions of the northern Plains, Great Lakes and Northeast each day. 
Accumulations for snow and ice are expected to be light with these
systems.

Farther to the south, it will feel more like spring. Daytime highs are
forecast to climb 10-30 above normal across most places from the central
and southern Plains to the Mid Atlantic and Southeast on Tuesday and
Wednesday, before colder starts to press south from the Upper Midwest and
Great Lakes later this week.
