High pressure around 30.4 inches will remain over the Gulf Coast states today into tonight, while strengthening low pressure to 29.4 inches tracks from southern Manitoba to across northern Lake Superior this afternoon, then to far southeast Ontario for Sunday morning. The resultant winds will yield southwest gales this afternoon and evening for the south half of the lake. A Gale Warning has been issued. Winds over the north half will be breezy and just below gale force.
Winds will diminish by Sunday morning, but modest south to southeast winds will develop late in the day and last through the night as low pressure approaches from the west. Low pressure around 29.5 inches will then move across Lake Superior on Monday and track toward James Bay for Tuesday. A cold front will shift the winds to brisk westerly on Monday with another shift to brisk northwest winds for Tuesday and Wednesday.
A Small Craft Advisory remains in effect late this morning into the early morning hours of Sunday for the nearshore waters from Sheboygan to Winthrop Harbor.
