A weak low pressure system over North Dakota will be tracking slowly east over the next 24 hours, bringing an area of rain to southern MB. The leading edge of the rain shield is just spreading up to the MB border from the south as of midday, and should continue edging north this afternoon likely reaching Winnipeg by mid to late afternoon. Rain amounts are expected to be in the 5 to 15 mm range, most of it falling south of Winnipeg closer to the international border. Here in Winnipeg, look for about 5 mm from late afternoon through tonight. Cool unsettled weather is expected behind this system for Friday through the weekend.
