breezy southwesterly winds with gusts up to 30 knots will persist

pressure around 30.3 inches begins to build down across the upper
midwest. thus a gale warning remains in effect for these strong
winds as they work north to south down lake michigan late this
afternoon through friday afternoon. may see gale conditions end 
sooner for northern portion of lake michigan. in addition to the
winds, cold air moving into the region friday and warmer lake

part of the lake michigan. then high pressure will build over the
