...Coastal low to produce locally heavy rainfall, gusty winds, and coastal
flooding along the Southeast Coast tonight and into Sunday morning...

...Rain and heavy mountain snow over parts of the Pacific Northwest and
Northern Rockies...

...Much above normal temperatures in the Heartland, coolest conditions in
the Northwest, temperatures returning to more seasonal levels in the
Northeast...

The most unsettled weather will be positioned along the Southeast coast
and in the Pacific Northwest. Starting in the Southeast, a potent cyclone
off the coast of northern Florida is responsible for causing gusty winds,
wind-driven rainfall, and considerably cooler temperatures from the
Carolina coast and southeast Georgia to northern Florida. Significant
coastal impacts are also occurring as brisk onshore winds send large
swells towards the Southeast coast. Coastal Flood Warnings and Advisories
are in effect through the day Sunday from the Virginia Tidewater all the
way south to Cape Canaveral. This storm gradually moves east on Sunday,
forcing the heaviest rainfall to move off the coast but gusty winds,
scattered showers, and coastal flooding should stick around for one more
day along the Carolina Coast. By Monday, the storm will have tracked far
enough off shore and weaken to the point where weather conditions along
the Southeast coast improves, although some lingering high surf is
possible.

Meanwhile, a frontal system tracking into the Pacific Northwest today is
ushering in Pacific moisture that is resulting in numerous showers and
areas of mountain snowfall. Even in wake of this system as it tracks
inland, persistent onshore flow will continue to direct Pacific moisture
towards the region on Sunday, meaning more rounds of coastal/valley
showers and mountain snow is anticipated. In total, snowfall accumulations
through Monday evening are forecast to be heaviest in the Cascades and
Olympic Ranges where 1 to 2 feet of snow is expected (heaviest totals in
the highest of elevations). Some measurable snowfall is also possible in
the Tetons, Absoroka, and Wind River Ranges as a wave of low pressure
along a slow moving frontal boundary generates periods of snow on Sunday.

Outside of the Southeast coast and the Pacific Northwest, the rest of the
Lower 48 can expect generally tranquil weather conditions to close out the
weekend and to kickoff the upcoming week. The coolest temperatures are set
to transpire in the Northwest and into northern California. Another cool
day is on tap in the Southeast but moderating temperatures return to the
Northeast on Sunday where temperatures bounce back to more seasonal
levels. Chilly lows stick around for one more day in the Mid-South where
some Frost Advisories are in place for Sunday morning. The warmest
conditions on Sunday will be found in the Heartland where high temps look
to soar into the 70s (some 80s too) in the central High Plains. By Monday,
80+ degree highs are possible in the Texas Panhandle while 60s return to
portions of the Northeast and Mid-Atlantic.
