5 DAY ICE DISCUSSION...  
 
THE COLD WILL SLOWLY LESSEN IT'S GRIP ON THE NORTHERN GREAT LAKES INTO  
NEXT WEEK BUT AREAS THAT HAVE SEEN ICE GROWTH THE LAST COUPLE OF WEEKS  
WILL CONTINUE TO EXPERIENCE ISSUES WITH THE ICE THROUGH THE WEEKEND AS  
TEMPERATURES WILL NOT GET MUCH ABOVE FREEZING. THIS WILL INCLUDE PARTS OF  
WHITEFISH BAY, THE SAINT MARY'S RIVER AND THE STRAITS OF MACKINAC. EAST  
TO NORTHEAST WINDS UP TO 30 KNOTS MAY HINDER ICE BREAKING OPERATIONS AND  
MAY RESULT IN DIFFICULTY KEEPING TRACKS OPEN. WARMER WEATHER AND LIGHTER  
WINDS EARLY NEXT WEEK WILL RESULT IN INCREASING ICE DETERIORATION ON THE  
NORTHERN LAKES NEXT WEEK.  
 
THE WARMER WEATHER WILL BE MORE PRONOUNCED ON THE SOUTHERN LAKES WHERE  
ABOVE NORMAL TEMPERATURES WILL CONTINUE INTO NEXT WEEK WITH VERY LITTLE OR  
NO ICE.
