Heaviest Rainfall to brush the Prairies
The double barrel storm system that will impact the northern Plains of the U.S. this weekend into Monday will bring steady rain to the extreme southeastern Prairies during the period, but I think the heaviest rainfall (50-100 mm for the 3 days) will track up near the northern Minnesota border then into parts of northwest Ontario.
The Winnipeg area will be on the northern edge of the steadier rain and I estimate 12-20 mm for the period, with much higher amounts to the southeast.
The Red River just south of the border between North Dakota and Minnesota is still experiencing minor flooding, but the river continues to fall. I expect this trend to more or less level out by the end of the weekend and into early next week, but flooding should continue to be minor.
