The storm system behind Monday's Oklahoma twister brought strong rainstorms to parts of the South on Tuesday evening before heading toward the Great Lakes and the Tennessee Valley.

"The threat for strong tornadoes will rapidly diminish in these areas after sunset, with the main threat becoming damaging straight line winds during the overnight hours," Morris said. "Isolated tornadoes will still be possible."

Rainstorms pushed through the Dallas area on Tuesday afternoon. A ground stop at Dallas-Fort Worth International Airport was later lifted.

    Storms are expected to move east on Wednesday and will extend from the Great Lakes south-southwestward into the Ohio River Valley and into the Deep South.

    Primary threats will be damaging winds and large hail, according to the National Weather Service. Isolated tornadoes also will be possible.

    Storms weren't restricted to the Great Plains and Midwest.

    The National Weather Service said weather spotters on Tuesday afternoon reported a possible tornado near Copake, New York, near the Massachusetts border.
