Great Lakes Ice Outlook
National Weather Service Cleveland Ohio

5 Day Ice Discussion...

An Arctic air mass over the Great Lakes will produce another night of
moderate to rapid ice growth on the lakes. Temperatures will warm mid week
as brisk southwest winds develop. Southwest winds will average 20 to 30
knots with locally higher wind speeds and gale warnings are in effect for
parts of Lake Superior. Some deterioration in the ice is likely through mid
week especially on the southern lakes. Ice that is not fast may move and
tracks may not hold.

The next cold front will drop across the Great Lakes on Thursday and much
colder air will spread back across the lakes by Friday. Slow to moderate
ice growth is likely again late in the week but the air mass will moderate
over the weekend, especially on the southern lakes.
