Southerly winds will continue across the lake through the evening, but expect it to increase and turn more west- southwesterly overnight ahead of an approaching cold front. May see a few showers and storms with the cold front. Then expect the front to push across Lake Michigan through the day Thursday with winds turning more to the northwest behind it later in the day Thursday. Northerly winds will persist into Friday, but gradually weaken as high pressure around 30.1 inch builds across the region through the end of the week.
