5 DAY ICE DISCUSSION...
...AN ICE ADVISORY HAS BEEN ISSUED FOR THE CENTRAL AND EASTERN
BASINS OF LAKE ERIE THROUGH THURSDAY MORNING...
WITH ARCTIC AIR IMPACTING THE REGION THE LAST COUPLE DAYS, ICE
COVERAGE HAS BECOME MORE EXPANSIVE, ESPECIALLY ACROSS SHALLOWER
WATERS WITH TOTAL ICE COVERAGE NOW AT 23%. THE BULK OF ICE COVERAGE
ON LAKE SUPERIOR REMAINS CONFINED TO THE SOUTHERN LAKESHORE WITH
MOST BAYS COMPLETELY COVERED. ICE HAS BEGUN TO DEVELOP ON THE
EASTERN AND WESTERN SHORES OF LAKE MICHIGAN WITH GREATEST ICE
COVERAGE OBSERVED IN GREEN BAY WITH EXPANDING ICE ALONG THE SOUTHERN
AND NORTHERN SHORES. ACROSS LAKE HURON, THE ICE COVERAGE HAS
INCREASED FROM ALPENA MI SOUTH TOWARDS THE ST. CLAIR RIVER. AS OF
THIS FORECAST, SAGINAW BAY AND LAKE ST. CLAIR ARE COMPLETELY FROZEN.
LAKE ERIE HAS THE MOST ICE COVERAGE WITH ICE OBSERVED ACROSS THE
WESTERN AND CENTRAL BASINS WITH AN OPENING ONLY IN THE OPEN WATERS
OF EASTERN BASIN.
MODERATE TO RAPID ICE FORMATION IS EXPECTED DURING THE NEXT FIVE
DAYS AS SURFACE TEMPERATURES OVER AND NEAR THE LAKES REMAIN SLIGHTLY
BELOW TO NEAR NORMAL INTO THIS WEEKEND. SURFACE WINDS ARE EXPECTED
TO AVERAGE 15 TO 25 KNOTS. THESE WINDS MAY RESULT IN NEW ICE
SHIFTING AND POTENTIALLY CLOSING SHIPPING CHANNELS ON LAKE ERIE
WHICH HAS RESULTED IN AN ICE ADVISORY FOR THE CENTRAL AND EASTERN
BASINS.
