...Severe thunderstorms will continue to affect the Lower Mississippi

Valley through late this evening but the threat is expected to lower and

shift east for Monday...

...A mix of rain and higher elevation snow will impact parts of the

western U.S. over the next 48 hours with temperatures trending colder on

Tuesday...

A major winter storm will move eastward from the Central Plains into the

Ohio Valley and Mid-Atlantic region tonight, bringing areas of snow,

sleet, freezing rain and gusty winds along its path. Gusty winds, locally

exceeding 40 mph, will create blizzard conditions from Kansas into

northwestern Missouri through this evening, with conditions improving from

west to east overnight tonight. Areas of heavy snow will spread eastward

through the Ohio Valley and central Appalachians tonight, reaching the

northern Mid-Atlantic by Monday morning. While winds will be weaker across

the Ohio Valley and Mid-Atlantic region,  occasional gusts up to 20-25 mph

will still be possible which will result in reduced visibilities from

snowfall or snow on the ground. Total snowfall accumulations of 6 to 12

inches are expected from southern Ohio to the D.C. metropolitan area.

South of the snow will be a mixture of sleet and freezing rain with

damaging ice accumulations which are expected to exceed 0.25 inches for

northern Kentucky and portions of southern West Virginia. Lighter, but

still hazardous ice accumulations generally between 0.10 and 0.25 inches

are expected along and east of the Blue Ridge Mountains into western North

Carolina and central/southern Virginia.

On the warm side of the storm system, severe thunderstorms capable of

producing tornadoes and damaging straight line winds will move east from

Arkansas and Louisiana into Mississippi and Alabama this evening. The

threat for severe thunderstorms is expected to wane overnight but increase

again for portions of southern Georgia and northern Florida on Monday,

though the threat is expected to be reduced compared to the Lower

Mississippi Valley.

The eastern storm system will exit quickly into the western Atlantic

Monday night with lingering snow showers downwind of the Great Lakes and

into the favored upslope regions of the central/northern Appalachians.

Much colder air will filter into the central and eastern U.S. in the wake

of the eastern storm system resulting in high temperature departures of

roughly 10 to 20 degrees below average for large portions of the Great

Plains to the East Coast on Monday and Tuesday.

Across the western U.S., a pair of relatively weak disturbances aloft will

bring a mixture of lower elevation rain and mountain snow from the Pacific

Northwest to the northern and central Rockies. Rain/snow totals are

expected to remain fairly light for the West and temperatures will be 5 to

15 degrees above average west of the Continental Divide on Monday. Colder

air filtering in from the north will cool temperatures closer to average

on Tuesday for much of the western third of the nation.
