northwest behind the front. close to the low expect strongest 
gusts to develop with gale force gusts across the northern third 
of the lake this evening into early saturday morning. then the low

northerly winds lingering until an arctic high pressure builds to 
around 30.7 inches across the upper midwest saturday evening and 
gradually slide east through the start of next week. expect 
lighter winds to accompany this high pressure and eventually turn 
southerly monday into mid next week.
