5 DAY ICE DISCUSSION...
TOTAL ICE COVER ACROSS THE GREAT LAKES IS CURRENTLY AT ~48%. FAST ICE
CONTINUES TO BE FOUND IN THE TYPICAL SPOTS ALONG THE SHORELINES, BAYS,
AND STRAIGHTS, WITH A LARGER SPATIAL FOOTPRINT ACROSS THE WESTERN BASIN OF
LAKE ERIE. FAST ICE IS ALSO FOUND ACROSS LAKE ST. CLAIR. LAKE ERIE
REMAINS LARGELY ICE- COVERED, WHILE ICE ON LAKE HURON CONTINUES TO
GRADUALLY BUILD FROM THE NEARSHORE INTO THE OPEN WATERS. THE OPEN WATERS
OF LAKES MICHIGAN AND SUPERIOR REMAIN RELATIVELY ICE-FREE.
GENERALLY SLOW TO MODERATE ICE GROWTH WILL CONTINUE ACROSS THE GREAT
LAKES INTO EARLY NEXT WEEK. A BRIEF PERIOD OF RAPID ICE GROWTH IS POSSIBLE
FRIDAY NIGHT THROUGH SATURDAY AS AN ARCTIC AIR MASS ARRIVES ACROSS THE
REGION, DROPPING AIR TEMPERATURES OVER THE LAKES INTO THE LOW TEENS AND/OR
SINGLE DIGITS. GUSTY NORTH TO NORTHWEST WINDS OF 25 TO 30 KNOTS WILL
ACCOMPANY THE ARCTIC AIR MASS FRIDAY INTO SATURDAY, WHICH MAY PUSH NON-
FASTENED ICE TOWARDS THE SOUTH TO SOUTHEAST. A PATTERN SHIFT FOR ABOVE
AVERAGE TEMPERATURES IS BECOMING MORE LIKELY BY MID TO LATE NEXT WEEK AND
WILL CONTINUE TO MONITOR FOR ANY ICE DECAY POTENTIAL.
