One more day of severe weather is ahead today in the eastern Great Lakes after a very active day across the Plains and Midwest, with several tornadoes already confirmed in the Midwest on Friday. Damaging winds will be the main threat as we move into the weekend.
Multiple tornadoes have already been confirmed. A tornado flipped a semi-tractor near Elgin, Minnesota, and caused damage on two farmsteads.

Severe Forecast
There may still be at least some isolated to scattered severe thunderstorms ahead of a cold front Saturday in the eastern Great Lakes and Ohio Valley.
But we're not expecting this activity to be nearly as widespread as Friday.
Fortunately, the nation should get at least a three-day break from severe weather as the cold front sweeps off the East Coast Sunday.

Flood Forecast
The combination of previous rounds of heavy rain and, in some areas, melting snow has already triggered serious flooding in parts of the western Great Lakes. Flooding is also possible as far south as Missouri due to heavy rain that will come with Friday's squall line.
Some stretches of rivers in Michigan and Wisconsin are eitherin or forecast to crest in major flood stage.
Flood watches and flood warnings continue for the areas below.
Why The Severe Parade?
What is going on here is actually pretty interesting. We have a high-pressure system that is sitting across the eastern U.S. This is forcing Gulf moisture to be pushed northward across the Plains.
We then have southward plunges of the jet stream, or troughs, pivoting out of the West into the Central Plains. Troughs like this generally bring severe weather.
Because of the high-pressure system across the East and the aforementioned troughs, severe weather may hit many of the same areas for days.
Recap
It's been a daily pounding of severe weather so far in the Plains and Midwest, from Texas to the Great Lakes, and even parts of the Northeast.
