More than 80,000 people in Ohio were without power early Tuesday morning following a massive tornado, but no deaths had yet been reported.

Local authorities used snowplows to clear debris from major thoroughfares.

On Memorial Day, 51 tornadoes were reported across eight states -- Idaho, Colorado, Nebraska, Iowa, Minnesota, Illinois, Indiana and Ohio -- and severe weather is forecast to continue Tuesday and Wednesday.

The biggest threat for tornadoes on Tuesday is from Kansas City into western Illinois. Parts of Ohio and Pennsylvania also are at risk again for tornadoes, while other areas including Oklahoma City and parts of Texas may again see damaging wind and hail.
