...COLD FRONT MOVES OFFSHORE OF THE EAST COAST, CAUSING THE WINTER  
WEATHER THREAT IN THE NORTHEAST AND HEAVY RAIN THREAT IN THE  
SOUTHEAST TO WIND DOWN...  
 
...SNOW WILL SPREAD FROM THE NORTHERN ROCKIES INTO THE PLAINS,  
MISSISSIPPI VALLEY, AND GREAT LAKES REGIONS...  
   
..WARMER THAN AVERAGE TEMPERATURES CONTINUE FOR THE WEST
 
 
THE WINTER STORM ACROSS THE NORTHEAST AND THE HEAVY RAIN ACROSS  
THE SOUTHEAST AND MID-ATLANTIC OCCURRING ON WEDNESDAY WILL WIND  
DOWN ON WEDNESDAY NIGHT AS THE COLD FRONT ASSOCIATED WITH THEM  
MOVES INTO THE WESTERN ATLANTIC OCEAN BY THURSDAY MORNING. BEFORE  
THEN, A FEW THUNDERSTORMS COULD BE STRONG AND CONTAIN LOCALLY  
HEAVY RAIN ACROSS PARTS OF THE SOUTHEAST WEDNESDAY NIGHT. ON A  
RELATED NOTE, THE LOWER MISSISSIPPI VALLEY AND SOUTHEAST ARE  
EXPECTING ANOTHER CHANCE OF RAIN AND THUNDERSTORMS ON FRIDAY AS  
MOISTURE STREAMS IN FROM THE GULF OF MEXICO. ON WEDNESDAY NIGHT,  
THE MAIN AREA WHERE ADDITIONAL SNOW IS EXPECTED IS IN PORTIONS OF  
NEW ENGLAND, WHERE 1 TO 4 INCHES OF SNOW IS POSSIBLE TO THE WEST  
OF A SURFACE LOW PRESSURE SYSTEM. LIGHTER LAKE EFFECT SNOW IS  
EXPECTED TO CONTINUE THROUGH THURSDAY, HOWEVER. LIGHT ACCUMULATING  
FREEZING RAIN IS POSSIBLE ALONG COASTAL MAINE WEDNESDAY EVENING  
AND NIGHT.  
 
A STATIONARY FRONT LINGERING ON THE EASTERN SIDE OF THE NORTHERN  
ROCKIES WILL BEGIN TO PUSH SLOWLY SOUTHWARD ON THURSDAY AND FRIDAY  
AS THE JET STREAM MOVES SOUTH INTO THE INTERMOUNTAIN WEST AND  
CENTRAL PLAINS. THE INCREASED UPPER-LEVEL SUPPORT AND SUFFICIENT  
MOISTURE MEANS THERE WILL BE HEAVY SNOW FOR THE NORTHERN ROCKIES  
AND THE BITTERROOT RANGE, WHERE OVER 2 FEET OF SNOW IS POSSIBLE  
FOR THE HIGHER PEAKS. SNOW WILL EVEN SPILL OUT INTO THE NORTHERN  
HIGH PLAINS--PORTIONS OF MONTANA EAST OF THE MOUNTAINS COULD SEE  
OVER A FOOT OF SNOW. AS A FRONT MOVES INTO THE CENTRAL PLAINS ON  
THURSDAY AND FORMS ACROSS THE MIDDLE MISSISSIPPI VALLEY AND UPPER  
GREAT LAKES BY FRIDAY, SNOW WILL SPREAD NORTH OF THE FRONT. PARTS  
OF THE MIDWEST, INCLUDING THE CHICAGOLAND AREA, ARE CURRENTLY  
EXPECTING 6 TO 10 INCHES OF SNOW THROUGH FRIDAY EVENING.  
 
THE WESTERN U.S., WITH THE EXCEPTION OF THE PACIFIC NORTHWEST,  
WILL REMAIN WARM AND DRY THROUGH THE END OF THE WORKWEEK.  
TEMPERATURES ARE FORECAST TO BE 10 TO 20 DEGREES ABOVE AVERAGE,  
AND A FEW RECORD HIGHS ARE POSSIBLE, PARTICULARLY ON THURSDAY. ON  
THE OTHER HAND, COLD AIR WILL SPILL INTO THE NORTH CENTRAL U.S.,  
AND BY FRIDAY TEMPERATURES IN THE NORTHERN HIGH PLAINS COULD BE  
OVER 30 DEGREES BELOW AVERAGE.
