A rip-roaring squall line (or line of severe thunderstorms) that got under way in the heart of the Midwest Monday night and has spawned tornadoes and caused widespread damage from Tennessee to Illinois, Wisconsin, Michigan and Ohio Tuesday.
A tornado reportedly touched down in Louisville, Ky., as the thunderstorms blew through around 11:30 a.m. EDT Tuesday.
This dangerous line will continue racing eastward through tonight, expanding the damage swath all the way through Ohio and Kentucky before it plows through the Northeast. Destructive winds and tornadoes will remain the primary threats.
Tornadoes have been sighted in southeastern Wisconsin, northeastern Illinois, north-central and southeastern Indiana, western Kentucky and northwestern Ohio. Major structural damage was noted with a tornado in Cridersville, Ohio.
Damage to homes was also reported with twisters near Peotone, Ill., and Kokomo, Ind., while another reportedly uprooted and downed trees onto homes near Racine, Wis.

Thunderstorms that ripped through Indianapolis just before 9 a.m. CDT, produced funnel clouds and 60-mph wind gusts with trees and power lines downed. At least 30,000 customers were reportedly without power.
The line will continue roaring eastward at about 60 mph through tonight but will eventually start to weaken. If you are able to safely take photos or video of the damage from these thunderstorms, be sure to post them on our AccuWeather.com Facebook page.
Areas farther south into Tennessee and northern parts of Alabama and Georgia will also remain in the risk area through early tonight. Some cities in this zone include Huntsville, Ala., and Knoxville, Tenn.
People in the path of these thunderstorms need to stay alert to their local weather conditions and head to the lowest level of a sturdy building immediately if a severe thunderstorm or tornado warning is issued.
These thunderstorms will be knocking trees and power lines down, potentially onto roadways, buildings and vehicles. Often times when this happens, lives are tragically lost.
Again, some of the thunderstorms could also spawn more tornadoes. Any tornado that touches down in a populated area could be devastating.
As the thunderstorms head farther east through New York, Pennsylvania and West Virginia tonight, threats for destructive winds and tornadoes will drastically decrease. However, that is not to say that the thunderstorms could still bring quick-hitting gusty winds to places such as Syracuse and Binghamton, N.Y., and State College and Harrisburg, Pa.
Even though the nasty thunderstorms will exit the Midwest tonight, howling winds will pick up behind them through Wednesday with gusts up to 70 mph threatening to cause more wind damage.
