More severe thunderstorms threaten to accompany the powerful storm system marching across the country.
While a widespread outbreak of severe weather is not expected, some thunderstorms rumbling from near Lake Michigan to northeastern Texas will be capable of turning severe Saturday afternoon and evening.
Major cities in the path of these storms include Milwaukee, Wis., Madison, Wis., Chicago, Ill., and Little Rock, Ark.
Damaging winds and drenching downpours are the biggest threats with these storms as they rumble across the region. Small hail is also possible.
As of Saturday evening, counties south of Chicago reported several street closures due to flooding from the storm's rainfall.
Multiple tornadoes spun across extreme southeastern South Dakota, northwestern Iowa and northeastern Nebraska on Friday evening injuring people and damaging multiple structures.
The Associated Press reported that at least 15 people sustained injuries when one tornado tore through Wayne, Neb.
A farmhouse to the southwest of Wayne was destroyed, allowing cows to run loose along the highway. A vehicle was also flipped upside down.
A tornado outbreak is not expected on Saturday, but an isolated tornado cannot be ruled out.
Saturday evening, law enforcement reported a tornado touchdown along the Tennessee, Kentucky border in Elbridge, Tenn. A little later, multiple funnel clouds were reported near Packwaukke, Wis., according to local emergency management.
Thunderstorm wind gusts topped out above 60 mph in several locations, including a 70-mph estimated gust near Monroe, Iowa, on Friday morning.
The collision of chilly air arriving from the West with warm, moist air in place over the lower Great Lakes and Ohio Valley will provide a conducive environment for Saturday's severe thunderstorms.
Winds may gust between 40 to 60 mph, but isolated higher gusts are possible. Trees and power lines can be brought down with this kind of strength. Power outages are possible and motorists should keep an eye out for downed power lines.
Flooding issues may arise as well, as torrential downpours batter areas. Ponding of water and quick rises in streams and small creeks should be expected.
College football games may be impacted as storms roll through. Folks heading to the Ohio State and Northwestern showdown could encounter strong storms. Arizona State and Notre Dame's game may also be impacted.
The severe potential is expected to gradually taper off late on Saturday night. Some thunderstorms will also turn severe on Sunday from Buffalo, N.Y., to Nashville, Tenn. Gusty winds and drenching downpours will again be the concern.
