Synopsis
Low pressure, 29.50 inches, clips the northern Great Lakes this evening into early Monday, pushing a cold front down across the region. This brings some additional showers to the central Great Lakes with a period of elevated winds/waves. The strongest wind are expected later this afternoon into Monday morning, when northwest winds prevail behind the cold front. Drier conditions expected early next week.
