...GUSTY WINDS TO REMAIN ACROSS THE NORTHEAST IN THE WAKE OF A  
DEPARTING COASTAL STORM TODAY...  
 
...SHOWERS AND THUNDERSTORMS WILL MOVE EAST FROM THE CENTRAL  
PLAINS INTO THE MID-MISSISSIPPI VALLEY THROUGH SUNDAY WHERE MAJOR  
TO HISTORIC RIVER FLOODING CONTINUES...  
 
...UNSETTLED CONDITIONS EXPECTED OUT WEST WITH LIGHT TO MODERATE  
RAIN/MOUNTAIN SNOW...  
 
A STRONG COASTAL LOW WHICH BROUGHT HEAVY SNOW TO PORTIONS OF NEW  
ENGLAND AND HEAVY RAIN TO THE MID-ATLANTIC REGION WILL CONTINUE TO  
PULL AWAY FROM THE NORTHEAST TODAY, BRINGING ANY LINGERING SHOWERS  
ALONG WITH IT. HOWEVER, A REMAINING TIGHT PRESSURE GRADIENT  
BETWEEN THE DEPARTING LOW AND HIGH PRESSURE SITUATED OVER THE OHIO  
VALLEY WILL AID IN GUSTY WINDS FOR MUCH OF THE NORTHERN  
MID-ATLANTIC AND NORTHEAST TODAY WITH WIND GUSTS EXPECTED TO RANGE  
BETWEEN 25 AND 35 MPH. THEREFORE, DESPITE A FAIR DEGREE OF  
SUNSHINE EXPECTED, GUSTY WINDS COMBINED WITH BELOW AVERAGE  
TEMPERATURES FROM THE UPPER OHIO VALLEY INTO THE NORTHEAST WILL  
MAKE FOR A COOL START TO THE FIRST WEEKEND OF SPRING. TEMPERATURES  
LOOK TO WARM TO NEAR AVERAGE FOR SUNDAY BEFORE A STRONG COLD FRONT  
REACHES NORTHERN NEW ENGLAND BY SUNDAY NIGHT WHICH WILL BRING THE  
BEGINNING OF A COLD SURGE TO MUCH OF THE EASTERN U.S. FOR EARLY  
NEXT WEEK.  
 
A STORM SYSTEM IN THE SOUTHERN AND CENTRAL U.S. WHICH WAS  
RESPONSIBLE FOR SEVERE WEATHER IN THE TEXAS PANHANDLE ON FRIDAY  
WILL MOVE EAST TODAY AND SUNDAY. WHILE WIDESPREAD SEVERE STORMS  
ARE NOT ANTICIPATED BY THE STORM PREDICTION CENTER, A FEW STRONGER  
STORMS CANNOT BE RULED OUT FROM PORTIONS OF THE SOUTHERN PLAINS  
INTO THE OZARKS THIS WEEKEND. ELSEWHERE, LIGHT TO MODERATE RAIN  
WILL BE POSSIBLE ATOP SECTIONS OF THE MISSOURI AND MISSISSIPPI  
RIVER VALLEYS WHICH ARE EXPERIENCING MAJOR FLOODING BUT WITH THE  
HEAVIEST RAIN LIKELY FOCUSING ACROSS SOUTHERN LOCATIONS FROM  
OKLAHOMA/TEXAS INTO THE LOWER MISSISSIPPI VALLEY.  
 
ACROSS THE WESTERN U.S., A WEAKENING UPPER LEVEL DISTURBANCE WILL  
MOVE INLAND TODAY BRINGING SCATTERED RAIN AND HIGHER ELEVATION  
SNOW FROM CALIFORNIA INTO THE GREAT BASIN, REACHING THE NORTHERN  
AND CENTRAL ROCKY MOUNTAINS ON SUNDAY. THE RELATIVELY WEAK NATURE  
OF THE STORM SYSTEM AND A LACK OF A BETTER MOISTURE FEED SHOULD  
LIMIT PRECIPITATION TOTALS THIS WEEKEND. A STRONGER STORM SYSTEM  
IS EXPECTED TO BRING ANOTHER ROUND OF RAIN AND MOUNTAIN SNOW TO  
THE WEST COAST SUNDAY NIGHT INTO MONDAY. AT THIS TIME, THE  
GREATEST RAINFALL THROUGH MONDAY MORNING APPEARS TO SET UP FROM  
SOUTHWESTERN OREGON INTO NORTHERN CALIFORNIA WITH HEAVY SNOW FOR  
THE MOUNTAINOUS REGIONS OF NORTHERN CALIFORNIA.
