...A SIGNIFICANT SOUTHERN WINTER STORM WILL WRAP UP TONIGHT INTO
SATURDAY MORNING AS IT SLIDES OFF THE MID-ATLANTIC COAST...
...PACIFIC STORM TO BRING WIDESPREAD SNOWS AS IT RACES ACROSS THE
NORTHERN GREAT BASIN AND THE NORTHERN PLAINS INTO THE UPPER
MIDWEST AND UPPER GREAT LAKES THIS WEEKEND...
THE SIGNIFICANT WINTER STORM THAT BROUGHT WIDESPREAD IMPACTS TO
MUCH OF THE SOUTH OVER THE PAST COUPLE OF DAYS WILL WRAP UP
TONIGHT INTO SATURDAY MORNING AS THE ASSOCIATED LOW PRESSURE
SYSTEM QUICKLY SWEEPS EASTWARD OFF THE MID-ATLANTIC COAST. PRIOR
TO ITS EXIT, WIDESPREAD LIGHT TO MODERATE SNOW WILL FALL FROM THE
TENNESSEE VALLEY TO THE MID-ATLANTIC. THE HIGHEST SNOWFALL
ACCUMULATIONS WILL BE CONFINED TO THE HIGHER ELEVATIONS OF THE
CENTRAL AND SOUTHERN APPALACHIANS AS WELL AS SOUTHERN VIRGINIA
WHERE AN OVERALL 3 TO 6 INCHES (WITH LOCALLY HIGHER AMOUNTS) IS
EXPECTED. LIGHTER SNOWS WILL EXTEND NORTHWARD INTO THE OHIO VALLEY
AND PARTS OF THE NORTHEAST WHICH WILL RESULT IN ROUGHLY 1 TO 3
INCHES OF ACCUMULATION. TO THE SOUTH OF THE HEAVIEST SWATH OF
SNOW, FREEZING RAIN AND DISRUPTIVE ICING WILL BE A CONCERN ACROSS
PORTIONS OF THE CAROLINAS, PARTICULARLY FOR THE CHARLOTTE AND
RALEIGH METRO AREAS WHERE A TENTH TO THREE TENTHS OF AN INCH OF
ICE IS EXPECTED. THE WIDESPREAD FOOTPRINT OF BOTH SNOW AND ICE
COMBINED WILL LEAD TO ADDITIONAL IMPACTS, INCLUDING DANGEROUS
TRAVEL CONDITIONS AND POWER OUTAGES. MOST LOCATIONS WILL START TO
DRY OUT BY SATURDAY AFTERNOON IN THE WAKE OF THE STORM, BUT
TEMPERATURES WILL PLUMMET BY AS MUCH AS 10 TO 20 DEGREES BELOW
NORMAL THROUGH THE REMAINDER OF THE WEEKEND.
A FAST-MOVING PACIFIC STORM HAS PUSHED INTO THE PACIFIC NORTHWEST,
WHICH BROUGHT COASTAL RAINS AND MOUNTAIN SNOWS TO MUCH OF
WASHINGTON AND OREGON THIS MORNING AND EARLY AFTERNOON. THIS
SYSTEM WILL QUICKLY RACE ACROSS THE NORTHERN GREAT BASIN AND INTO
THE NORTHERN PLAINS TONIGHT INTO SATURDAY MORNING, PRODUCING
WIDESPREAD SNOWS AS IT DOES SO. THE MOST SIGNIFICANT ACCUMULATIONS
WILL OCCUR IN THE HIGHEST ELEVATIONS OF THE NORTHERN AND CENTRAL
ROCKIES WHERE ACCUMULATIONS IN EXCESS OF 1 TO 2 FEET ARE LIKELY.
THE STORM WILL SCOOT ACROSS THE NORTHERN PLAINS AND INTO THE UPPER
MIDWEST BY SUNDAY, BRINGING WIDESPREAD LIGHTER SNOWS TO THOSE
REGIONS WITH A GENERAL 1 TO 4 INCHES OF ACCUMULATION.
