...East Coast winter storm to bring freezing rain to the southern and
central Appalachians and heavy snow to the Northeast today...

...Areas of heavy rain with possible flash flooding and severe
thunderstorms for the Gulf Coast and Florida today...

...Pacific storm system to bring heavy mountain snow, strong winds and and
coastal rain to the West this weekend...


An upper disturbance centered over the Great Lakes will support a winter
storm across the eastern third of the country this weekend. Expect heavy
snow in interior portions of the northern Mid-Atlantic through New England
this afternoon into Sunday. There is a high chance (50-90%) of exceeding
8" of snow from central Pennsylvania east through much of south-central
New England. Local snowfall over 12 inches of snow is possible within the
heaviest bands. The combination of heavy, wet snow and gusty winds from
northeast Pennsylvania through much of the southern and central New
England will result in difficult travel with some power outages and tree
damage. Gusty onshore winds may lead to minor flooding along the
Mid-Atlantic and southern New England coasts during the Sunday morning
high tide cycle. The probability for ice accumulations in excess of 0.25"
along the Blue Ridge of North Carolina and Virginia are 30-50%. This icing
along with some areas of sleet, may produce hazardous travel conditions
today. Winter Storm Watches Warnings and Winter Weather Advisories are in
effect for portions of the Central Appalachians and interior Northeast.
Meanwhile, rain showers and scattered thunderstorms are likely across the
southern Mid-Atlantic and Southeast within the warm sector of the winter
storm today.

The next winter storm shifts down the West Coast today crossing the Desert
Southwest Sunday before rapidly strengthening over the Southern
Rockies/Plains Sunday night/Monday. Expect heavy snow in the higher
elevations near the West Coast and Four Corners states this weekend before
a swath of heavy snow develops over parts of the Southern/Central Plains
on Monday. Gusty winds on the warm side of the storm may exceed 50 MPH and
cause damage over the Appalachians to the East Coast. Organized severe
thunderstorms are possible along the Gulf Coast and Southeast Monday and
Tuesday. There is a Slight Risk (at least 15%) of Excessive Rainfall
leading to Flash Flooding across portions of the central Gulf Coast on
Monday. Yet another storm system will arrive over the Pacific Northwest on
Monday, bringing with it coastal showers and mountain snow.
