...Major winter storm will produce additional heavy snow for Northeast and
Central Appalachians today...

...Rapidly strengthening storm will lead to widespread, significant
impacts over much of the central U.S. beginning Monday...

...Major winter storm will dump several feet of snow over the Washington
and Oregon Cascades 


There are three storm systems that are and/or will be impacting the CONUS
over the next few days. The first of the three is the major winter storm
bringing heavy snow and strong winds to the Northeast and Central
Appalachians today. Additional snowfall of 4-8 inches are expected for
much of the aforementioned areas through tonight when the storm is
expected to pull away into the Atlantic. Winter Storm Warnings and Winter
Weather Advisories are in effect. Conditions should improve on Monday.

The second storm system is one that will make its way through the Rockies
today. Heavy snow is likely across much of the Intermountain West and
Central/Southern Rockies. Snow is also likely over the Northern Rockies
but to a lesser extent. This system will reorganize over the Southern
Plains on Monday and develop into a deep and dynamic mid-latitude cyclone.
This storm will generate heavy snow and strong winds over the Plains and
Midwest on Monday and Tuesday. The heaviest snow totals are most likely in
parts of the Midwest, where local maxima up to 12 inches are likely.
Blizzard conditions are most likely in the Central Plains where wind gusts
in excess of 50 mph will lead to near zero visibility at times and
extremely dangerous travel. Blizzard conditions are possible in the
Midwest as well. Winter Storm Watches are in effect for parts of the
Southern High Plains, Central Plains and Middle Mississippi Valley.

Widespread and potentially significant river and flash flooding are likely
from the central Gulf Coast through much of the Eastern U.S. early this
week. Powerful onshore winds will lead to widespread coastal flooding
along the eastern Gulf Coast and much of the East Coast. Significant
coastal flooding is likely in some areas, especially in the Carolinas and
Mid-Atlantic. There is a Slight Risk of Excessive Rainfall leading to
Flash Flooding for portions of the Gulf Coast. Storms will support 1.5 to
2.5 inch/hr rain rates with localized amounts of 4 to 6 inches possible.
There is a Slight Risk of Severe Thunderstorms Monday through Monday night
across parts of southeast Texas, southern Louisiana, southern Mississippi,
southern Alabama into the western Florida panhandle. Damaging wind gusts
and tornadoes are possible across those areas by late Monday night.
Widespread wind gusts in excess of 50 mph are likely in the eastern Gulf
Coast so prepare for power outages.

The third system arrives over the Pacific Northwest tonight. A deep
Pacific storm system will generate heavy coastal rain, heavy mountain snow
and strong winds across the region beginning tonight and continuing
through at least midweek. This major winter storm will bring several feet
of snow to the Washington and Oregon Cascades and will peak on Tuesday and
Wednesday.
