A few strong to severe storms could bring winds up to 60 mph and quarter sized hail between 6 pm and midnight, primarily in areas near the South Dakota border and into into parts of west central Minnesota including Grant County. Heavy rainfall in the risk area may lead to increased chance for flash flooding especially in more urban areas.
Low pressure will move east thru northern South Dakota tonight. This low will bring an area of showers and thunderstorms to much of the area, spreading eastward this afternoon and ending Wednesday morning. Heaviest rainfall southeast ND & west central MN where probabilities of 1 inch or more are over 50 percent. Much lighter rainfall as you go north to the Canadian border where not much will fall.
