through the central great lakes during the day. a brief period of
gale force winds appears likely for the central portions of lake

lifting into the region friday will flip the winds to the
southwest/south by friday evening...with gusts of 25 to 30 knots
expected over much of lake huron before milder air and greater
stability arrives over the weekend.
