Severe thunderstorms will threaten areas from south-central Canada to the Nebraska Panhandle Sunday into Sunday evening.
Some of those areas were rattled Saturday afternoon and evening by large hail and gusty winds from thunderstorms, especially eastern South Dakota and western Nebraska. Hail up to 2" in diameter pounded the Rapid City, S.D. area and they are in the threat area once again.
In addition to large hail, damaging winds and downpours are possible with the most intense storms. The risk is low but isolated tornadoes can also occur, but conditions will be most favorable for tornadoes across far southeast Saskatchewan, southwest Manitoba and western North Dakota.
Brandon, Manitoba and Bismarck, N.D. could be affected and travel along Interstates 90, 94 and 80 may be impacted, especially from blinding downpours and flooding.
As Sunday night progresses thunderstorms will evolve into an organized complex and move eastward across eastern North Dakota and into northern Minnesota. There is the potential for downpours and damaging winds across those areas.
