..HEAVY RAIN EXPECTED ACROSS SOUTHERN FLORIDA
 
 
...WINTER STORM TO UNFOLD ACROSS THE UPPER MIDWEST AND GREAT  
LAKES...  
 
...BITTER COLD ACROSS THE UPPER GREAT LAKES WILL LAST THROUGH THE  
WEEKEND...  
 
A FRONT HAS STALLED OFF THE SOUTH FLORIDA COAST AND WILL BEGIN TO  
PUSH NORTHWARD OVERNIGHT AND INTO SUNDAY MORNING. LIGHT TO  
MODERATE RAINFALL WILL CONTINUE ACROSS SOUTHERN FLORIDA THROUGH  
LATE SUNDAY NIGHT INTO EARLY MONDAY MORNING WHEN THE FRONT FINALLY  
PUSHES EASTWARD AWAY FROM THE STATE. THE HEAVIEST RAINFALL TOTALS  
ARE EXPECTED TO FALL FROM FT. MYERS INTO THE MELBOURNE REGION.  
FLASH FLOODING IS NOT EXPECTED; HOWEVER, SOME WATER COULD END UP  
PONDING ON ROADS OR LOW-LYING AREAS THAT DO NOT DRAIN WELL.  
 
AN UPPER LEVEL DISTURBANCE WILL DROP SOUTHWARD FROM CENTRAL CANADA  
AND WILL MOVE ACROSS THE UPPER MIDWEST AND GREAT LAKES. AT THE  
SURFACE, A LOW WILL DEVELOP IN SASKATCHEWAN, MOVE INTO THE PLAINS  
AND EASTWARD TOWARD THE UPPER MIDWEST. WITH PLENTY OF MOISTURE  
ACCOMPANYING THIS SYSTEM, AND COLD TEMPERATURES IN PLACE, SNOW  
WILL DEVELOP AND MOVE SOUTHWARD ACROSS THE EASTERN DAKOTAS TONIGHT  
AND INTO SUNDAY. BY MONDAY, AS THE SURFACE LOW MOVES TOWARD THE  
UPPER MIDWEST, HEAVY SNOW WILL IMPACT PORTIONS OF THE UPPER GREAT  
LAKES--PARTICULARLY ALONG THE SOUTHEAST WISCONSIN ALONG THE  
LAKE-SHORE REGION WHERE SNOW TOTALS COULD REACH OVER A FOOT. AS  
THE SYSTEM PROGRESSES EASTWARD ON MONDAY EVENING, SNOW WILL TAPER  
OFF ACROSS THE UPPER GREAT LAKES WHILE INCREASING ACROSS THE LOWER  
GREAT LAKES. IN ANTICIPATION OF THIS EVENT, WINTER STORM WATCHES  
HAVE BEEN ISSUED FROM NORTH-CENTRAL NORTH DAKOTA TO EASTERN  
WISCONSIN.  
 
BITTER COLD THAT HAS GRIPPED THE UPPER MIDWEST AND UPPER GREAT  
LAKES THE LAST FEW DAYS WILL CONTINUE ITS HOLD THROUGH SUNDAY.  
AREAS FROM NORTHERN MINNESOTA TO THE UPPER PENINSULA OF MICHIGAN  
CAN EXPECT HIGH TEMPERATURES TO NOT EVEN REACH ZERO DEGREES  
FAHRENHEIT FOR TOMORROW. MEANWHILE, FLORIDA WILL HAVE HIGH  
TEMPERATURES IN THE UPPER 50S AND LOWER 60S ON SUNDAY. BY MONDAY,  
SOME AREAS IN THE UPPER MIDWEST/UPPER GREAT LAKES WILL REMAIN  
COLD, HOWEVER TEMPERATURES WILL BEGIN TO REBOUND AND BECOME  
WARMER. A COLD FRONT ASSOCIATED WITH THE LOW CAUSING THE HEAVY  
SNOW FOR THE UPPER MIDWEST WILL SWEEP ACROSS THE PLAINS ON SUNDAY.  
THIS WILL CAUSE TEMPERATURES TO PLUNGE--WITH MOST HIGH  
TEMPERATURES NOT REACHING 32 DEGREES FAHRENHEIT (ABOUT 15-20  
DEGREES BELOW NORMAL). AS HIGH PRESSURE DOMINATES THE WESTERN  
U.S., TEMPERATURES ESPECIALLY ALONG THE WEST COAST WILL NEAR TO  
SLIGHTLY ABOVE NORMAL.
