Warm, moist air surging northward across the nation's heartland will set the stage for severe storms across the eastern Dakotas tonight.
As a storm system emerging from the northern Rockies plows into the unstable air mass, thunderstorms are expected to erupt this evening across the Dakotas. From there, they should rumble north and eastward through the night impacting the eastern Dakotas and possibly reaching far western Minnesota close to daybreak on Thursday.
The main threat from these storms will be damaging winds and large hail. There is a small likelihood of a tornado. Residents from Pierre and Aberdeen, S.D., to Fargo, N.D., could be in for a stormy night.
Large hail can produce damage to crops and property and gusty winds have the potential to down trees and power lines.
In addition to the severe weather, these storms can produce torrential rainfall in a short amount of time, leading to ponding of water on the roadways, reduced visibility and localized flooding.
Rounds of heavy rain and the risk of flash flooding are forecast to continue over part of the northern Plains and the Upper Midwest into next week.
Elsewhere across the nation, widespread damaging thunderstorms are not expected today or tonight. However, a few spotty strong storms could ignite this afternoon along and just south of the Red River in Texas.
While these storms can bring some gusty winds and hail, heavy rainfall could be a bigger threat, leading to some flooding.
Looking ahead at the end of the week, the severe weather threat will shift eastward into the Upper Midwest. Residents from Omaha, Neb., to St. Cloud, Minn., could see nasty storms tomorrow. Stay tuned to AccuWeather.com for updates.
