      Midwest under high storm threat

      A number of Midwestern states are awakening to the threat of a high risk of severe thunderstorms.

      The National Weather Service says parts of Illinois, Indiana, southern Michigan and western Ohio are at the greatest risk of seeing tornadoes, large hail and damaging winds Sunday.

      The agency says strong winds and atmospheric instability will sweep across the Central Plaines during the day before pushing into the Mid-Atlantic states and northeast by evening.

      It says the potential for strong and long-track tornadoes will center on the Ohio Valley and adjacent Midwestern states.

      Many of the storms are expected to become supercells, with the potential to produce tornadoes, large hail and destructive winds.

      The weather service says local and state authorities are monitoring the weather.

      Watches and Warnings in the Tri-States:

      A Wind Advisory is in effect for the Tri-State area until 6 p.m. for wind gusts to 50 MPH.
