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.
Our summer outlook for Canada will be released on Monday.
Update on weekend snow and a look at the long range.
My thoughts on the overall pattern into next week....
A small, but intensifying storm off the New England coast will track northeastward through the Maritimes by Wednesday.
Weather highlights into next week
The storm impacting parts of eastern Canada later tonight and into Saturday with snow will move fairly quickly and will not be all that intense, but it will have a decent amount of moisture with it.
Some hope may be on the horizon for those freezing in the East
