...DANGEROUS FREEZING RAIN ACCUMULATIONS POSSIBLE FROM EASTERN  
IOWA, EASTWARD ACROSS PORTIONS OF THE UPPER GREAT LAKES REGION...  
 
...TEMPERATURES WILL CONTINUE TO BE WELL BELOW AVERAGE FROM  
MONTANA INTO THE DAKOTAS AND WELL ABOVE AVERAGE FROM THE SOUTHERN  
PLAINS TO THE EAST COAST...  
 
...THE BEGINNING OF A POSSIBLE HEAVY RAIN/FLOODING PATTERN WILL  
SET UP FOR SECTIONS OF THE OHIO VALLEY BEGINNING WEDNESDAY...  
 
ACTIVE WEATHER WILL CONTINUE FOR LARGE SECTIONS OF THE COUNTRY  
OVER THE NEXT FEW DAYS WITH AN ONGOING PACIFIC STORM SYSTEM ACROSS  
THE WEST AND A STRONG FRONT CURRENTLY DRAPED FROM THE NORTHEAST TO  
THE SOUTHERN PLAINS. AS COLDER AIR FILTERS INTO THE WESTERN U.S.  
BEHIND A COLD FRONT, SNOW LEVELS WILL CONTINUE TO FALL FOR  
SOUTHERN CALIFORNIA TODAY AND LOWER FOR THE FOUR CORNERS REGION  
FOR WEDNESDAY. HEAVY SNOW CAN STILL BE EXPECTED FOR THE SIERRA  
NEVADA RANGE INTO THE MOUNTAINS OF SOUTHERN CALIFORNIA, AND  
EASTWARD INTO THE WASATCH AND COLORADO ROCKIES WHERE OVER A FOOT  
OF NEW SNOW IS EXPECTED THROUGH WEDNESDAY. HOWEVER, PRECIPITATION  
INTENSITY WILL BE WANING FROM WEST TO EAST AS THE STORM SYSTEM  
WORKS ITS WAY INTO THE GREAT PLAINS.  
 
TO THE NORTH OF A STRONG FRONT ACROSS THE CENTRAL U.S., HIGH  
TEMPERATURES FROM MONTANA INTO NORTHERN HIGH PLAINS WILL BE  
GENERALLY 20 TO 40 DEGREES BELOW AVERAGE OVER THE NEXT FEW DAYS,  
WITH THE COLDER AIR FILTERING SOUTH AND EAST FOR THURSDAY.  
LOCATIONS AHEAD OF THE FRONT FROM OKLAHOMA AND TEXAS INTO NEW  
ENGLAND AND THE MID-ATLANTIC STATES WILL SEE HIGH TEMPERATURES  
RANGE BETWEEN 10 AND 20 DEGREES ABOVE AVERAGE TODAY, WITH  
TEMPERATURES CLOSER TO AVERAGE ON WEDNESDAY FOR THE NORTHEAST BUT  
CONTINUING TO FEEL LIKE SPRING FOR LOCATIONS TO THE SOUTH.  
 
IT WILL BE NEAR AND NORTH OF THIS FRONTAL BOUNDARY ACROSS THE  
MIDWEST WHERE A DANGEROUS ICE STORM IS EXPECTED. A WINTRY MIX OF  
SLEET AND FREEZING RAIN IS EXPECTED TO BEGIN OVER IOWA INTO  
NORTHERN MISSOURI LATER TODAY, SPREADING NORTHEASTWARD TOWARD  
NORTHERN ILLINOIS/SOUTHERN WISCONSIN INTO LOWER MICHIGAN. RAIN  
WILL PICK UP IN INTENSITY TO THE SOUTH ACROSS SOUTHERN/CENTRAL  
MISSOURI INTO THE OHIO VALLEY. AS THE PACIFIC STORM SYSTEM  
MENTIONED ABOVE MOVES EAST WEDNESDAY INTO THURSDAY, THE RAIN/SNOW  
LINE WILL ADJUST NORTH BUT THE WINTRY MIX OF FREEZING RAIN AND  
SLEET WILL SHIFT INTO PORTIONS OF WISCONSIN AND LOWER MICHIGAN  
WITH HEAVY RAIN FOCUSING ACROSS THE OHIO VALLEY. STORM TOTAL  
RAINFALL MAY RANGE BETWEEN 2 TO 4 INCHES FOR PORTIONS OF THE OHIO  
VALLEY WHICH MAY CAUSE FLOODING CONCERNS.
