Thunderstorms capable of producing damaging winds and large hail are expected Sunday across parts of northern plains from northern Nebraska, across South Dakota, and into portions of eastern north Dakota, and much of southern Minnesota.
A cold front will be approaching this area late in the afternoon on Sunday. This will be the trigger mechanism for thunderstorm development. The greatest severe weather potential will come in the form of large hail, and damaging wind gusts. As evening sets in, storms will begin to evolve into a line, which will then create a damaging wind threat across southern Minnesota.
This line of storms will then continue to move to the east on Monday, which will then bring a threat of severe weather to the state. Currently there are a lot of uncertainties on if the best atmospheric dynamics will line up correctly to produce a widespread severe weather threat. However, it does appear that a few storms will be severe on Monday, with damaging winds the main threat. After this cold front moves through the state, cooler and calmer weather will set in for the remainder of the week.
