5 Day Ice Discussion...
Despite the relatively cold weather the past week or two, ice
coverage remains below average, though that will probably change as
we`ve see ice cover expand over the past several days.
Ice has continued to thicken and expand wherever it previously existed,
including southern Green Bay, and around Big and Little Bay De Noc, with
some fast ice near the shorelines in these locations. This is also
occurring along the southern shore of Lake Superior with higher
concentration west of the Keweenaw Peninsula, with fast ice in Chequamegon
Bay. Ice continues to further develop around the Sault Ste. Marie area on
Lake Nicolet, Munuscong Lake, and parts of the St. Marys River, with some
fast ice in these locations. Ice continues to expand in Saginaw Bay and
Thunder Bay near Alpena. Ice greatly expanded in the western basin of Lake
Erie primarily west of the islands with fast ice in Saginaw Bay.
Now that we are in the heart of January, we will continue to see
sustained below-freezing temperatures through the next five days
(and likely beyond). Coldest temperatures are expected through the next
couple days which will result in moderate growth for the entire Great
Lakes before temperatures become a bit warmer Saturday through Monday
(though still below freezing), so may seem more slow growth on though days
for the central and southern Great Lakes.
