VALID 12Z SUN DEC 02 2018 - 12Z TUE DEC 04 2018  
 
...WINTER STORM ACROSS THE PLAINS AND MIDWEST WILL WIND DOWN  
TODAY...  
 
...SEVERE WEATHER AND POTENTIALLY HEAVY RAIN ARE POSSIBLE IN THE  
SOUTHEAST TO CAROLINAS TODAY...  
 
A SURFACE LOW PRESSURE SYSTEM WILL CONTINUE TO TRACK NORTHEASTWARD  
OVER THE NEXT COUPLE OF DAYS, MOVING ACROSS THE GREAT LAKES REGION  
AND INTO ONTARIO AND QUEBEC. SNOW IS FORECAST TO CONTINUE ON THE  
NORTH AND WEST SIDES OF THE LOW, BUT SNOW IS EXPECTED TO WIND DOWN  
ACROSS THE PLAINS AS THE LOW PULLS AWAY. A COLD FRONT IS FORECAST  
TO FORM ACROSS THE GREAT LAKES REGION TO OHIO AND MIDDLE  
MISSISSIPPI VALLEYS, WHICH WILL LEAD TO CONTINUED CHANCES FOR  
LIGHT SNOW THERE THROUGH SUNDAY NIGHT. FARTHER EAST, SNOW OF 1 TO  
4 INCHES IS EXPECTED ESPECIALLY DOWNWIND OF THE GREAT LAKES, AS  
WELL AS IN NORTHERN NEW ENGLAND CLOSER TO THE LOW TRACK. FREEZING  
RAIN IS ALSO LIKELY IN NORTHERN NEW ENGLAND, WITH A TENTH OF AN  
INCH OF ICE POSSIBLE IN SOME AREAS.  
 
FARTHER SOUTH, RAIN AND THUNDERSTORMS ARE FORECAST AHEAD OF THE  
COLD FRONT ASSOCIATED WITH THIS LOW PRESSURE SYSTEM. THE STORM  
PREDICTION CENTER HAS A SLIGHT RISK OF SEVERE WEATHER IN PLACE FOR  
PARTS OF THE SOUTHEAST INTO THE CAROLINAS ON SUNDAY--PLEASE SEE  
THEIR WEBSITE FOR MORE DETAILS ON THE SEVERE THREAT. THERE IS  
MARGINAL RISK OF FLASH FLOODING OUTLOOKED IN THE SAME GENERAL AREA  
ON SUNDAY, WHERE STORMS COULD MOVE SLOWLY AND TRAIN OVER THE SAME  
LOCATIONS. MOST OF THE REGION WILL DRY OUT ON MONDAY AFTER THE  
FRONTAL PASSAGE, THOUGH RAIN AND THUNDERSTORMS WILL CONTINUE  
ACROSS FLORIDA THROUGH MONDAY NIGHT AS THE FRONT LINGERS.  
 
A LOW PRESSURE SYSTEM WILL MOVE ACROSS THE SOUTHWEST AND SOUTHERN  
ROCKIES ON SUNDAY, LEADING TO SNOW THE SOUTHWEST AND INTERMOUNTAIN  
WEST, WITH HIGHER TOTALS IN HIGHER ELEVATIONS OF THE WASATCH AND  
SAN JUAN MOUNTAINS. NORTHERN ARIZONA COULD RECEIVE 6 TO 10 INCHES  
OF SNOW IN MOUNTAIN PEAKS, WITH 4 TO 8 INCHES IN THE WASATCH.  
WIDESPREAD WINTER WEATHER ADVISORIES ARE IN EFFECT THERE, BEFORE  
SNOW CHANCES WIND DOWN MONDAY MORNING. ANOTHER LOW APPROACHING THE  
WEST COAST WILL HELP CREATE MORE CHANCES OF RAIN AND SNOW IN  
CALIFORNIA AND THE INTERMOUNTAIN WEST BY MONDAY NIGHT.  
 
TEMPERATURE-WISE, THE EASTERN U.S. WILL BE MILD FOR THE BEGINNING  
OF THE WEEK, WITH HIGH TEMPERATURES 10 TO 20 DEGREES ABOVE AVERAGE  
EXPECTED IN THE TENNESSEE AND OHIO VALLEYS EASTWARD ON SUNDAY, AND  
ALONG THE EASTERN SEABOARD ON MONDAY (WHILE THE TENNESSEE AND OHIO  
VALLEYS BECOME CLOSER TO NORMAL ON MONDAY DUE TO A COLD FRONTAL  
PASSAGE). RECORD WARM TEMPERATURES ARE EXPECTED, PARTICULARLY FOR  
HIGH MINIMUM TEMPERATURES ON MONDAY MORNING. COLDER THAN AVERAGE  
TEMPERATURES ARE FORECAST FOR THE WESTERN AND CENTRAL PARTS OF THE  
U.S.
