Clusters of severe thunderstorms are forecast today and tonight across parts of the upper Midwest and and Midwest. A cluster of storms will likely develop during the afternoon/early evening with an attendant threat for hail, wind and possibly a tornado.
The greatest tornado potential will exist across southwest Iowa. The tornado threat risk may be somewhat dependent on storms developing on the northern edge of the cap across the lower Missouri Valley. It may also depend on storms acquiring supercell characteristics before upscale growth occurs.
Storms will grow upscale and will pose another primary risk for strong/severe gusts as they move east southeastward across the lower Missouri Valley.
