VALID 12Z SUN DEC 10 2017 - 12Z TUE DEC 12 2017  
 
...LOCALLY HEAVY LAKE EFFECT SNOWFALL TO CONTINUE DOWNWIND OF THE  
GREAT LAKES...  
   
..CRITICAL FIRE WEATHER PERSISTING ACROSS SOUTHERN CALIFORNIA
 
 
RELATIVELY QUIET WEATHER WILL BE IN STORE FOR MUCH OF THE COUNTRY  
AS A WINTER STORM CONTINUES TO PULL AWAY FROM THE NORTHEAST SUNDAY  
MORNING. A QUICK MOVING AND MOISTURE STARVED UPPER LEVEL  
DISTURBANCE WILL BRING A CHANCE OF LIGHT SNOW SHOWERS TO THE  
NORTHEAST TODAY/TONIGHT BUT THE GREATEST SNOWFALL ACCUMULATIONS  
WILL BE EAST OF LAKES ERIE AND ONTARIO DUE TO LAKE EFFECT SNOW  
WHERE LOCAL TOTALS UP TO A FOOT ARE FORECAST INTO MONDAY.  
 
HEAVY LAKE EFFECT SNOW ACCUMULATIONS WILL ALSO BE POSSIBLE ACROSS  
THE MICHIGAN U.P. MONDAY NIGHT INTO TUESDAY BEHIND A QUICK MOVING  
CLIPPER SYSTEM. THIS CLIPPER IS EXPECTED TO DROP INTO THE  
NORTH-CENTRAL U.S. TONIGHT BRINGING LIGHT SNOW, 1 TO 3 INCHES, TO  
NORTHERN MINNESOTA AND WISCONSIN BY MONDAY AFTERNOON.  
 
REGARDING TEMPERATURES, THE EAST COAST WILL BE 5-15 DEGREES BELOW  
AVERAGE TODAY WITH SOME MODERATION ON MONDAY. MOST OF THE PLAINS  
WILL BE 10 TO 25 DEGREES ABOVE AVERAGE TODAY AND MONDAY WITH  
WESTERLY TO NORTHWESTERLY DOWNSLOPE WINDS AT THE SURFACE. WINDS  
WILL ALSO BE GUSTY AT TIMES, ESPECIALLY ON MONDAY AFTER THE  
PASSAGE OF A COLD FRONT TIED TO THE AFOREMENTIONED CLIPPER SYSTEM.  
THESE WINDS WILL ALSO GENERATE DRY CONDITIONS LEADING TO AN  
ELEVATED RISK FOR WILDFIRES EXTENDING THROUGHOUT PARTS OF THE  
SOUTHERN AND CENTRAL HIGH PLAINS THROUGH MONDAY.  
 
THE GREATER RISK OF WILDFIRES WILL BE ACROSS CALIFORNIA THOUGH,  
WHERE CRITICAL FIRE WEATHER CONDITIONS WILL PERSIST THROUGH AT  
LEAST MONDAY GIVEN CONTINUED STRONG SANTA ANA WINDS AND LOW  
RELATIVE HUMIDITIES.
