An active day for severe weather is coming up for the Northern Plains as waves of storms rotate around the developing heat dome. The storms will come in waves and will produce damaging wind gusts, large hail and even a few tornadoes. The area of western North Dakota into eastern Montana will be the focal point for the main impacts of the storms.
The storms will probably form into an MCS (Mesoscale Convective System) overnight that will feed on the heat coming up from the Plains. That MCS will move through Minnesota into Wisconsin with strong winds and heavy rains.
The same pattern will occur across the Upper Midwest Friday into Saturday as another round of heavy storms and nocturnal storms develop.
Check out the rotation streaks map below. That shows where supercell thunderstorms may develop and produce strong rotation, perhaps even a tornado.
