Severe weather likely today into Wednesday

GRAND FORKS – The National Weather Service has indicated that a “significant, widespread” severe weather outbreak is likely to occur today and into Wednesday for counties in eastern North Dakota and west-central to northwest Minnesota.

An unusually strong low-pressure system moving across the area from Canada is to blame, according to the National Weather Service’s statement. This system is expected to intensify as it travels from British Columbia to the North Dakota and Minnesota area.

Because of the unusual pressure system, the conditions will be right to create rotating supercell thunderstorms that are capable of producing tornadoes. In addition, the region can expect strong wind gusts, “very large hail,” and heavy rains capable of producing flash flooding conditions.

Isolated thunderstorms may develop over the Devils Lake basin late today, but severe weather is most likely to begin this afternoon and extend into Wednesday morning, the weather service says.
