southerly gales over the northern two thirds of lake michigan

few gusts over 35 kt could linger through midnight for far

gusts up to 25 kt are expected in the wake of this front

west to northwest winds will settle across the lake thursday as
high pressure around 30.1 inches moves into the northern plains.
winds will once again become southerly on friday as the high
departs the upper great lakes and low pressure around 29.2
inches approaches from the northern plains/canadian plains.
