Thunderstorms with large hail and damaging winds were possible in Arkansas then Tennessee and Kentucky before the threat moved on towards Alabama and Mississippi.

"These storms will be moving quickly and effect most locations for up to 30 minutes so voters will be inconvenienced but if they wait out the storms weather will clear out quickly," NBC News forecaster Bill Karins said.

The cold side of the front was expected to bring snow in Wisconsin and Michigan, while interior New York and northern New England were set for snow Tuesday night through Wednesday morning, Karins added.
