An unseasonably strong low pressure system is moving into Manitoba today. Rain and thunderstorms are already entering the province to the south/southwest of Winnipeg mid this afternoon. All this is along a cold front. More rains and embedded storms are in southwestern Manitoba and western North Dakota as well. All this is moving northeastwards.
Due to the northeastwards movement of these storms, excessive rainfall amounts will be possible in the RRV beginning within the next couple hours. Up to 50 mm of rain will be possible locally, with generally lower amounts. Large hail will also be possible, and as a result EC has issued severe thunderstorm watches for south-central and southeastern Manitoba. An isolated funnel cloud or tornado cannot be ruled out in the province today.
