.SYNOPSIS...

Westerly winds will increase across the northern half of Lake
Michigan as the pressure gradient increases between a deepening
low pressure around 29.3 inches tracking across northern Ontario
and incoming high pressure around 30.4 inch building across MN/IA
border and into southern WI. Expect lighter, but still breezy
west- northwest winds across the southern half. Then winds
gradually weaken as the low departs to the north and the high
pressure continues to build across the Western Great Lake Region
Friday before pushing east Saturday. Winds veer more southerly and
pick up on Saturday ahead of an incoming low pressure system from
the Central Plains.
