...Heavy snow to blanket much of the Northwest...
...Areas of showers and thunderstorms to develop over the Southeast and
Lower Mississippi Valley...
...Unseasonably mild temperatures to persist across the Eastern U.S.,
bitterly cold in the Northern Rockies/Plains...
The Northwest will have an active stretch of weather as a pair of storm
systems track through the region over the next couple days and a steady
current of onshore flow will aid in producing the precipitation . Wintry
weather is the headliner with numerous Winter Storms Warnings and Winter
Weather Advisories in effect from the Cascades of Washington and Oregon,
eastward to the Central Rockies. Snowfall will be measured in feet in the
Cascades, the Northern Sierra Nevada, Northeast Oregon, Northern and
Central Idaho, Western Wyoming, North-Central Utah, and the Colorado
Rockies. Winter Storm Watches have also been issued for the Seattle metro
area as they may pickup a few inches of snow. Expect treacherous and icy
travel conditions in these affected areas.
A frontal boundary will become quasi-stationary from the Mid-Atlantic
Coast stretch southwest across parts of the Tennessee Valley and into the
Western Gulf Coast. Scattered showers and thunderstorms will form along
the front and could lead to localized areas of flash flooding. Some
thunderstorms could also be severe over parts of the Tennessee Valley and
Lower Mississippi Valley.
Unseasonably mild temperatures will continue across the Southeastern U.S.
in wake of the big weekend storm system. Record warm daily high and low
temperatures will be possible in parts of the Southeast through Wednesday.
Temperature anomalies on average will range between 10-20 degrees above
normal across much of the Mid-Atlantic/Southeast and into the Central
Appalachians. Farther west, bitterly cold temperatures will engulf much
of Montana and the Western Dakotas with high temperatures are forecast to
be below zero on Monday and Tuesday.
