5 DAY ICE DISCUSSION...
MILDER CONDITIONS THIS WEEK HAVE ALLOWED TOTAL ICE COVER ON THE
GREAT LAKES TO DECREASE TO 47.1%. LAKE ERIE REMAINS MOSTLY ICE
COVERED, WITH FAST ICE COVERING THE ENTIRE WESTERN BASIN WEST OF THE
ISLANDS, WHILE GREATER MOVEMENT OF THE ICE SHEET IS TAKING PLACE
ACROSS THE CENTRAL AND EASTERN BASINS. MOST OF THE LAKE ERIE ICE IS
MEDIUM THICKNESS. FAST ICE COVERS LAKE SAINT CLAIR, SAGINAW BAY, THE
SAINT MARY'S RIVER, STRAITS OF MACKINAC, GREEN BAY, AND MUCH OF THE
SOUTHERN SHORE OF LAKE SUPERIOR, INCLUDING WHITEFISH BAY. ICE IS
THICK IN MOST OF THESE AREAS, ESPECIALLY IN THE RIVERS AND BAYS.
THIN TO MEDIUM THICKNESS ICE COVERS MUCH OF SOUTHERN LAKE HURON,
WESTERN AND CENTRAL LAKE SUPERIOR, AND THE SHORES OF LAKE MICHIGAN,
WITH CONCENTRATION GENERALLY IN THE MEDIUM TO HIGH RANGE.
ANOTHER WARMING TREND WILL TAKE PLACE THIS WEEKEND ACROSS THE ENTIRE
GREAT LAKES REGION, AND THE WARMING TREND WILL PEAK MONDAY THROUGH
WEDNESDAY OF NEXT WEEK WHEN HIGHS IN THE 50S ARE EXPECTED ACROSS THE
SOUTHERN AND CENTRAL GREAT LAKES, WITH 40S IN THE NORTHERN GREAT
LAKES. TEMPERATURES FALLING BELOW FREEZING AT NIGHT WILL SUPPORT
SLOW ICE GROWTH DURING NIGHTTIME HOURS THIS WEEKEND, BUT ICE DECAY
IS EXPECTED TO ACCELERATE EARLY TO MID NEXT WEEK. THE GREATEST ICE
DECAY WILL OCCUR IN THE CENTRAL AND SOUTHERN GREAT LAKES, INCLUDING
LAKE MICHIGAN, SOUTHERN LAKE HURON, AND LAKE ERIE. MAINLY LIGHT
WINDS ARE EXPECTED THROUGH EARLY NEXT WEEK, BUT SOUTH WINDS
INCREASING TO 15-20 KNOTS IN THE SOUTHERN GREAT LAKES WEDNESDAY
COMBINED WITH THE WARM TEMPERATURES COULD CAUSE DANGEROUS ICE FLOES.
