Hazardous thunderstorms are possible Saturday across the Central Plains, Midwest, and Southwest. Heavy rain is possible across the Upper Midwest.

Central Plains & Midwest: A developing surface low pressure area is forecast to move east-northeast across the Great Plains on Saturday, while an associated warm front extending east-southeast from the low lifts northward. Thunderstorms are likely to initially develop across the region during the afternoon hours, then potentially increase in coverage and intensity by the evening and overnight hours. Large hail, damaging winds, and an isolated tornado or two will initially be possible, with the threat transitioning more to a possible widespread damaging wind event, especially across eastern Nebraska and western Iowa, by the overnight hours.

Southwest:An upper level low is continue shifting slowly eastward across the 4-corners regions and into the central Rockies on Saturday. This low combined with instability and increase low-level moisture will bring a threat of strong or marginally severe thunderstorms to the region, especially during the afternoon and early evening hours. Thunderstorms should begin to weaken near sunset with the loss of daytime heating. Large hail and damaging winds will be the main threats with the strongest activity.

Upper Midwest: Surface low pressure lifting east-northeast towards the western Great Lakes will bring periods of showers and thunderstorms to the northern United States on Saturday. Some prolonged and heavy rainfall made lead to a swath of excessive rainfall stretching from eastern North Dakota eastward through northern Minnesota. Rainfall amounts in excess of 2 inches will be possible, which may lead to an increased flooding threat for the region.
