...Temperatures will be 15 to 25 degrees above average over the Plains and
parts of the Mississippi Valley...
A storm over the Pacific Northwest will move inland to the Upper
Mississippi Valley by Monday. Onshore flow off the Pacific will stream
moisture into Northern California/Northwest through to Sunday evening.
The moist flow will aid in producing light to moderate rain along the
Pacific Northwest Coast through Sunday morning. The rain will become
light on Sunday into Monday morning. Snow may develop at highest
elevations also from Sunday morning into Monday.
Rain and higher elevation snow will develop over the Northern
Intermountain Region/Northern Rockies likewise from Sunday morning into
Monday morning. The rain and higher elevation snow will spread into parts
of the Northern High Plains/Central Rockies Sunday evening into Monday.
As the associated front moves out of the Rockies and onto the Plains, rain
will develop over parts of the Upper Mississippi Valley into the Upper
Great Lakes, again, from Sunday evening into Monday morning. Rain will
also develop over parts of the Central Plains on Monday morning.
Meanwhile, a front over the Lower Great Lakes will move eastward off the
Northeast Coast by Sunday morning. Light rain will develop over parts of
the Northeast through Sunday morning. Northwest flow and upper-level
energy rotating around and upper-level low over Eastern Canada will
trigger light rain over parts of the Northern Appalachians on Sunday into
