5 Day Ice Discussion...
As mentioned in previous discussions, Lake Erie continues to be 80-90
percent ice covered, however the majority of it not fastened to the
shorelines and continues to shift with the wind directions. Across the
rest of the Great Lakes down to Buffalo, the Straits of Mackinac remain
primarily ice covered with large areas of fast ice on the Lake Michigan
side. Whitefish Bay, most of Green Bay, Saginaw Bay, and Lake St. Clair
are all ice covered as well. Other ice covered areas beyond that are
primarily shoreline ice, and the Great Lakes currently sits at around 27
percent ice covered.
Over the next 5 days, the northern Great Lakes will remain below freezing,
with a colder airmass moving in after Monday. For the southern Great
Lakes, temperatures will be much closer to freezing, or just slightly
above for afternoon high temperatures during the period. These areas will
be subject to temperature fluctuations from low pressure system
originating from the intermountain west that will keep the coldest air
further north. Otherwise, ice coverage growth can be expected during the
5 day period through early next week.
