Outlook:
Multiple rounds of severe storms are anticipated as a disturbance moves through an unstable airmass across portions of the central Plains and the Mississippi Valley from this afternoon through the overnight hours. These storms will be capable of producing very large hail, destructive gusty winds, and isolated tornadoes if conditions align. For detailed information on timing, impacts, and more, refer below.
Detailed Forecast Across the Central Greater Plains through Mississippi Valley
An upper trough over the northern Rockies will move east toward the Upper Midwest and Great Lakes region. By Friday morning, a convectively concentrated weather system will move east toward Lake Michigan by evening. At the surface, an area of low pressure will be near the international border in North Dakota and southern Saskatchewan, shifting east into northern Minnesota and eventually the Upper Peninsula of Michigan and Lake Superior. As this happens, a cold front will move southeast across the northern Plains and Upper Midwest, guiding the airmass further south.
