strengthening from 30.3 inches to 30.5 inches. gusty northerly
winds will continue through tonight into tomorrow morning, with
winds becoming northwesterly saturday afternoon. while the
northerly winds continue, a lake effect band of rain is expected
over the middle of lake michigan, with the heaviest potential
precipitation over the southern half of lake michigan. while the
lake effect band continues, some waterspouts may be possible
with any deeper convection within the band. the band should then
end saturday afternoon as the northwesterly winds advect the

night as the high pressure center moves in.

light northwesterly winds then continue through sunday, with
winds then coming around to southwesterly sunday night into
monday as the high pressure pushes east. breezy southwesterly
winds will then be possible through next week.
