.MARINE...
South-southwest winds strengthen through the morning between
departing high pressure and low pressure pushing into the northern
Great Lakes. Strongest winds, gusting 25-30kts, occur over central
Lake Huron and Saginaw Bay this afternoon/early evening with the
southern portions of the area expected to hold closer to 15-20kts. A
Small Craft Advisory is in effect for Saginaw Bay and around the tip
of the Thumb. Low weakens as it drops south near or directly over
Lake Huron late today-Saturday which aids in keeping winds under
30kts. Scattered showers can be expected for this timeframe as will
waterspout chances as the cooler airmass is reinforced. A weak area
of ridging, induced by low pressure systems over the northern Plains
and Atlantic seaboard, then expands over the local area Sunday-
Monday.
