...WINTER STORM EXPECTED TO PRODUCE WIDESPREAD SNOW AND SOME  
FREEZING RAIN FROM THE OHIO VALLEY TO THE MID-ATLANTIC REGION...  
 
THE MAIN WEATHER EVENT MAKING HEADLINES THROUGH THE REMAINDER OF  
THE WEEKEND WILL BE THE ONGOING WINTER STORM ACROSS THE EASTERN  
U.S. WITH THE OCCLUDED OVER TENNESSEE WEAKENING SUNDAY MORNING, A  
NEW SURFACE LOW IS DEVELOPING NEAR THE SOUTHEAST U.S. COAST, AND  
THIS WILL RESULT IN ENHANCED PRECIPITATION ACROSS MUCH OF THE  
MID-ATLANTIC REGION AND EXTENDING SOUTHWARD ACROSS THE CAROLINAS.  
WINTER STORM WARNINGS ARE IN EFFECT FROM WESTERN NORTH CAROLINA TO  
THE DELMARVA REGION FOR VARIOUS WINTER WEATHER IMPACTS. AREAS  
ACROSS CENTRAL AND NORTHERN VIRGINIA INTO MARYLAND HAVE THE  
POTENTIAL OF 5 TO 10 INCHES OF SNOW BY SUNDAY NIGHT, WITH LOCALLY  
HIGHER AMOUNTS POSSIBLE. SIGNIFICANT SLEET AND FREEZING RAIN IS  
EXPECTED ACROSS SOUTHWEST VIRGINIA AND WESTERN NORTH CAROLINA,  
WITH ICE ACCRETION PERHAPS EXCEEDING A QUARTER INCH FOR SOME  
AREAS. THERE WILL LIKELY BE SEVERE DISRUPTIONS TO TRAVEL ALONG  
WITH THE POTENTIAL FOR POWER OUTAGES, PARTICULARLY FOR THOSE AREAS  
THAT GET SIGNIFICANT ICING. WARMER TEMPERATURES OVER  
CENTRAL/EASTERN NORTH CAROLINA AND INTO SOUTHEAST VIRGINIA WILL  
KEEP THIS EVENT MOSTLY A COLD RAIN.  
 
ELSEWHERE ACROSS THE CONTINENTAL U.S., A STORM SYSTEM OVER THE  
EASTERN PACIFIC WILL APPROACH SOUTHERN CALIFORNIA ON MONDAY, AND  
RESULT IN ENHANCED RAINFALL FOR PARTS OF CENTRAL AND SOUTHERN  
CALIFORNIA THROUGH MONDAY NIGHT AS A RESULT, WITH SOME RAINFALL  
TOTALS IN THE 1 TO 2 INCH RANGE FOR THE COASTAL MOUNTAIN RANGES.  
DRY CONDITIONS ARE EXPECTED FROM THE PACIFIC NORTHWEST TO THE  
CENTRAL U.S. WITH A LARGE SURFACE HIGH GOVERNING THE WEATHER  
PATTERN. MOST OF NEW ENGLAND SHOULD ALSO REMAIN DRY AS THE WINTER  
STORM STAYS SOUTH OF THAT REGION.
