A cold front pushing across southern Manitoba today will usher in a westerly flow of drier and cooler air this afternoon into tonight. West winds gusting to 60 or 70 km/h are likely this afternoon into this evening across the Red River valley as drier air pushes in from the west (see real time wind readings from Winnipeg airport). Strong wind warnings have been posted over the Lake Manitoba and southern Lake Winnipeg marine areas for sustained westerly to northwest winds of 30 knots later today into tonight, with west to northwest gales of 40-45 knots forecast over the north basin of Lake Winnipeg by tonight. These strong winds will cause already high lake levels to rise another 0.5 to 1 metre on the east and south side of the lakes, with waves of 1-2 metres on top of that.
