southern half of the lake friday, backing northeast with 15-20 
kt gusts saturday morning, then north-northeast with gusts up to
25 kt saturday afternoon and evening. an additional period of 
breezy north winds may unfold sunday afternoon and evening as 
high pressure builds over lake superior (20-30 kt possible). 
slower winds and gusts expected over the north half of lake 
michigan through the aforementioned timeframes.
