Frost warning for tonight
6/5/2009 at 5:26 PM
After a cool cloudy day in which temperatures struggled to reach the double digits, skies are expected to clear this evening in southern Manitoba as a ridge of high pressure builds in from the west. This will result in temperatures dropping below freezing over almost all of southern Manitoba overnight giving widespread frost.
