...HEAVY PRECIPITATION RETURNING TO CALIFORNIA AND RELATIVELY  
UNEVENTFUL WEATHER ACROSS MOST OF THE NATION...  
 
THE RECENT WINTER STORM ACROSS THE MID-ATLANTIC REGION HAS BEEN A  
RATHER IMPRESSIVE EVENT WITH HEAVY SNOW ON THE ORDER OF 10+ INCHES  
FOR SOME AREAS IN NORTHERN VIRGINIA AND MARYLAND, AND SIGNIFICANT  
ICING FROM FREEZING RAIN ACROSS WESTERN NORTH CAROLINA AND INTO  
SOUTHERN VIRGINIA. NOW THAT THIS LOW PRESSURE SYSTEM IS EXITING  
THE COAST, OUR ATTENTION NOW TURNS TO CALIFORNIA AND THEN THE  
INTERMOUNTAIN WEST FOR THE BEGINNING OF THE WORK WEEK. A DEEP  
PACIFIC TROUGH OFF THE WEST COAST WILL REMAIN IN PLACE OVER THE  
NEXT FEW DAYS WITH A FRONTAL BOUNDARY APPROACHING SOUTHERN  
CALIFORNIA MONDAY NIGHT, AND ADDITIONAL SHORTWAVE IMPULSES  
ARRIVING THROUGH TUESDAY. THE RESULT WILL BE WIDESPREAD RAIN WITH  
SOME LOCALIZED FLOODING ISSUES POSSIBLE FOR THE COASTAL MOUNTAIN  
RANGES. HEAVY SNOW IS LIKELY FOR THE SIERRA NEVADA AND SISKIYOU  
MOUNTAINS OF CALIFORNIA, WITH AMOUNTS POSSIBLY EXCEEDING A FOOT AT  
THE HIGHEST ELEVATIONS.  
 
ELSEWHERE ACROSS THE CONTINENTAL U.S., A MAINLY DRY WEATHER  
PATTERN IS EXPECTED THROUGH TUESDAY AS A LARGE SURFACE HIGH  
REMAINS IN PLACE. A STRONG COLD FRONT DROPS SOUTHWARD ACROSS THE  
PLAINS ON TUESDAY AND INTO EARLY WEDNESDAY, BRINGING FRIGID  
TEMPERATURES TO THE DAKOTAS AND THE UPPER MIDWEST BY THE MIDDLE  
PART OF THE WEEK. THERE SHOULD BE ENOUGH MOISTURE WITH THIS FRONT  
TO PRODUCE SOME MIXED PRECIPITATION OVER THE LOWER GREAT LAKES AND  
SNOW SHOWERS BEHIND THE FRONT OVER NORTHERN MICHIGAN. SOME  
SHOWERS ARE LIKELY ACROSS SOUTHERN TEXAS WITH SOME ONSHORE FLOW  
FROM THE GULF OF MEXICO.
