...MAJOR WINTER STORM ABATING ACROSS THE MID-ATLANTIC REGION AND  
RAIN/MOUNTAIN SNOW RETURNS TO PACIFIC NORTHWEST...  
 
THE WINTER STORM THAT HAS BEEN HAMMERING THE INTERIOR SOUTHEAST  
U.S. AND PARTS OF THE MID-ATLANTIC REGION THIS PAST WEEKEND IS NOW  
MOVING OFFSHORE, AFTER PRODUCING ONE TO TWO FEET OF SNOW ACROSS  
NORTHWEST NORTH CAROLINA AND SOUTH-CENTRAL VIRGINIA. HOWEVER,  
SOME LIGHTER MIXED WINTRY PRECIPITATION IS EXPECTED TO LINGER  
ACROSS PARTS OF THESE SAME AREAS ON MONDAY AS AN UPPER LEVEL  
DISTURBANCE PASSES THROUGH THE REGION, AND LEADS TO A SECONDARY  
SURFACE LOW OFF THE MID-ATLANTIC COAST. TRAVEL CONDITIONS REMAIN  
HAZARDOUS FOR MANY OF THESE AREAS AFFECTED, AND ADDITIONAL POWER  
DISRUPTIONS ARE POSSIBLE.  
 
ACROSS THE WESTERN U.S., A PACIFIC COLD FRONT MAKING ITS WAY  
INLAND IS EXPECTED TO PRODUCE SNOW SHOWERS FROM THE SIERRA NEVADA  
TO THE NORTHERN ROCKIES THROUGH MONDAY NIGHT. A SECOND STORM  
SYSTEM APPROACHING THE PACIFIC NORTHWEST ON TUESDAY WILL LIKELY  
PRODUCE HEAVIER PRECIPITATION FROM WESTERN WASHINGTON TO IDAHO,  
WITH HEAVY SNOW FOR THE CASCADES AND A COUPLE INCHES OF RAINFALL  
AND GUSTY WINDS NEAR THE COAST.  
 
MUCH OF THE CENTRAL U.S. SHOULD BE VOID OF ANY SIGNIFICANT  
PRECIPITATION FOR THE BEGINNING OF THE WORK WEEK AS A LARGE  
SURFACE HIGH CONTINUES TO GOVERN THE WEATHER PATTERN. THIS ALSO  
HOLDS TRUE FOR THE DESERT SOUTHWEST AND THE OHIO VALLEY REGION.  
TEMPERATURES ARE EXPECTED TO BE BELOW NORMAL ACROSS MUCH OF THE  
CENTRAL AND EASTERN U.S. ON MONDAY, AND THEN SOME MODERATION BY  
TUESDAY. THE WARMEST READINGS WILL CONTINUE FOR THE SOUTHWESTERN  
U.S. THROUGH EARLY WEDNESDAY.
