...A STRONG NOR'EASTER WILL CONTINUE TO SPREAD HEAVY SNOW OVER  
PORTIONS OF THE NORTHEAST...  
 
...UNSETTLED WEATHER IS EXPECTED ACROSS THE WEST WITH RAIN AND  
SNOW...  
 
A STRONG NOR'EASTER IMPACTING NEW ENGLAND WILL LIFT UP ACROSS THE  
GULF OF MAINE TODAY AND THEN GRADUALLY WEAKEN TONIGHT AND FRIDAY  
AS THE CENTER OF LOW PRESSURE THEN MOVES INLAND ACROSS INTERIOR  
SECTIONS OF MAINE. ADDITIONAL HEAVY SNOW IS EXPECTED ACROSS  
INTERIOR PORTIONS OF THE NORTHEAST, AND ESPECIALLY NORTHERN NEW  
ENGLAND WITH ADDITIONAL SNOWFALL AMOUNTS OF 12 TO 18 INCHES  
EXPECTED. SOME ACCUMULATING SNOW WILL BE EXPECTED AS WELL AROUND  
THE LOWER GREAT LAKES REGION AND CENTRAL APPALACHIANS AS  
ADDITIONAL ENERGY ALOFT DROPS DOWN TO THE SOUTHEAST ACROSS THE  
REGION. MEANWHILE, THE REMAINDER OF THE EASTERN U.S. WILL BE  
GENERALLY COLD THROUGH THE REMAINDER OF THE WEEK AS A WELL-DEFINED  
UPPER TROUGH SETTLES SOUTHEASTWARD. HIGH TEMPERATURES WILL  
GENERALLY BE AS MUCH AS 10 TO 15 DEGREES BELOW NORMAL.  
 
OVER THE WESTERN U.S., MULTIPLE SURFACE WAVES OF LOW PRESSURE AND  
SUPPORTING ENERGY ALOFT WILL LEAD TO A BROAD AREA OF PRECIPITATION  
OVER THE NEXT COUPLE OF DAYS. RAIN WILL CONTINUE TO SPREAD ACROSS  
THE PACIFIC NORTHWEST AND NORTHERN CALIFORNIA TODAY AS A COLD  
FRONT MOVES INLAND. THIS WILL ALLOW THE GREAT BASIN TO SEE  
UNSETTLED WEATHER ARRIVE WITH A COMBINATION OF RAIN AND SNOW BY  
TONIGHT AND CONTINUING THROUGH FRIDAY. HEAVY SNOW WILL OCCUR OVER  
THE HIGHER ELEVATIONS, INCLUDING THE CASCADES AND THE NORTHERN  
ROCKIES. SNOWFALL ACCUMULATIONS OF AS MUCH AS 1 TO 2 FEET CAN BE  
EXPECTED THROUGH FRIDAY. RAINFALL TOTALS IN THE LOWER ELEVATIONS  
OF THE INTERIOR WILL GENERALLY BE LIGHT, BUT THE COASTAL RANGES OF  
WASHINGTON, OREGON AND FAR NORTHERN CALIFORNIA WILL SEE SOME  
LOCALLY HEAVY RAINFALL WITH AS MUCH AS 1 TO 2 INCHES. TEMPERATURES  
ACROSS THE WEST WILL GENERALLY BE SOMEWHAT ABOVE NORMAL GIVEN THE  
INFLUX OF PACIFIC AIR ACROSS THE REGION.  
 
THE REMAINDER OF THE COUNTRY IS EXPECTED TO BE DRY AND RELATIVELY  
MILD WITH TEMPERATURES GENERALLY ABOVE NORMAL. THIS WILL  
ESPECIALLY BE THE CASE ACROSS THE CENTRAL AND SOUTHERN HIGH PLAINS  
WHERE TEMPERATURES WILL BE AS MUCH AS 10 TO 20 DEGREES ABOVE  
NORMAL. THE DRY CONDITIONS ACROSS THIS REGION AND WARM  
TEMPERATURES WILL COMBINE WITH LOW HUMIDITY TO ALSO SUPPORT SOME  
ADDITIONAL CONCERNS FOR WILDFIRE ACTIVITY.
