5 DAY ICE DISCUSSION...
OVERALL GREAT LAKES ICE COVERAGE REMAINS IN A SLOW BUT STEADY
DECLINE DOWN TO AROUND 31 PERCENT. THE BULK OF THIS COVERAGE
CONTINUES TO BE IN LAKE ERIE, LAKE ST. CLAIR, LAKE HURON, AND THE
STRAITS OF MACKINAC/FAR NORTHERN LAKE MICHIGAN, WITH LAKE SUPERIOR
CONTRIBUTING AS WELL. AS THE MONTH ROUNDS OUT, EXPECTING FAIRLY
TYPICAL WEATHER PATTERNS FOR THIS TIME OF YEAR AS THE NORTHERN GREAT
LAKES LARGELY REMAIN BELOW FREEZING FOR THE NEXT SEVERAL DAYS WHILE
THE SOUTHERN GREAT LAKES WILL EXHIBIT DIURNAL FREEZE/THAW CONDITIONS
WITH HIGHS ABOVE FREEZING, THEN BACK BELOW FREEZING AT NIGHT. WHILE
ACROSS THE NORTH, TEMPERATURES WILL BE SUPPORTIVE OF ICE FORMATION,
WE ARE GETTING INTO THE TIME OF YEAR WITH INCREASING SUN ANGLES AND
LENGTHS OF DAYS THAT START TO INHIBIT ADDITIONAL ICE GROWTH. WILL
NOT PUT THAT POTENTIAL AT ZERO YET BY ANY MEANS, BUT THIS PROCESS
WOULD BE SLOWER THAN IF IT WAS EARLY JANUARY, AND WITH THE PEAK ICE
COVERAGE TYPICALLY IN MID FEBRUARY, WE ARE STARTING THE NATURAL
DECREASE OF ICE COVERAGE WITH NEAR NORMAL WEATHER FOR THE NEXT 5 DAYS.
