Rounds of severe weather to center on north-central US this week

The north-central United States will face rounds of locally heavy and severe thunderstorms through Thursday.

"An eastward-moving system originating over the northern Rockies will create a multi-day severe weather setup for the northern Plains and Upper Midwest," AccuWeather Storm Warning Meteorologist Brian Adams said.

The system will clash with heat and humidity over the North Central states, adding fuel to the storms.

The zone at the greatest risk for severe weather will push eastward each day with the system's progression, shifting from the Dakotas on Tuesday and Wednesday to Minnesota, Wisconsin and Iowa on Thursday.

The main threats with each round of storms will include damaging wind gusts, large hail and flash flooding, Adams said.

Isolated tornadoes will also be possible.

Storms are expected to first take aim at parts of western Montana, North Dakota and South Dakota late on Tuesday afternoon into Tuesday night.

The storms will likely be highly localized during the afternoon hours, before becoming more numerous toward evening.

Glasgow and Miles City, Montana; Rapid City and Aberdeen, South Dakota; and Bismarck, North Dakota are a few of the cities that may experience stormy weather for part of Tuesday.

On Wednesday, the threat for locally damaging and drenching storms will shift slightly eastward, encompassing portions of the central and eastern Dakotas and western Minnesota.

Locally heavy rain can produce flash flooding, even in the absence of severe weather across the region.

Damage to trees, structures and crops may be caused by some of the strongest storms.

Motorists on interstates 29, 35 and 94 could face torrential downpours and ponding on the roadway for a time on Wednesday and Wednesday night.

Locally heavy and gusty storms could reach Minneapolis by Thursday morning, though they will likely have weakened.

On Thursday, the zone at the greatest risk for severe storms will expand farther eastward and southward.

Locations from Wisconsin and Minnesota to Iowa, Nebraska and Kansas, are the most likely areas for locally violent storms during Thursday afternoon and evening.
