Synopsis -
west to northwest winds will persist today as high pressure around 30.1 inches pushes into the region. Winds will become southerly on Friday as the high departs and low pressure around 29.2 inches develops in the northern plains. The tight pressure gradient over lake michigan will produce breezy southerly winds up to 30 knots from Friday night through Sunday morning. A few gale force gusts may occur in the northern half of the lake Saturday afternoon and evening.
lighter winds are expected Monday as a weak low pressure trough around 29.7 inches slowly moves from minnesota to wisconsin. Look for gusty northwest winds to develop Monday night into Tuesday after the passage of a cold front as high pressure of 30.1 inches builds into the upper midwest.
