      Midwest under high storm threat

      Adam Lucio saw this tornado near Roanoke, Illinois around 12:30pm EST

      CHICAGO (AP) - Fans heading to today's Bears-Ravens game in Chicago are being warned of the possibility of severe weather.

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

      Forecasters say strong storms are rare this late in the year because there usually isn't enough heat from the sun to sustain the thunderstorms, but temperatures today are expected to reach into the 60s and 70s.

      The weather service 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.
