SYNOPSIS

Modest north to northeast winds tonight will become light and variable Sunday afternoon into Sunday night as high pressure around 30.7 inches tracks from the northern Great Lakes to the lower Great Lakes. Breezy south winds will then develop on Monday in response to the high shifting east and low pressure moving across far northern Ontario. A weak cold front will then bring a return of light northeast winds by Tuesday afternoon.
