Severe weather outbreak could spawn strong tornadoes in South on Tuesday

A dangerous severe weather outbreak is expected Tuesday in parts of the South, where strong, long-track tornadoes, destructive winds, large hail and flash flooding will all be serious threats through the overnight hours.

The Twin Cities area of Minneapolis and St. Paul is among the regions expecting plowable snow, with 3-6 inches possible during the day Tuesday, potentially snarling both the morning and evening commute. Travel impacts are possible along interstates 80, 90 and 35 in the Upper Midwest.

"The heaviest snow totals will be in northwestern Wisconsin through Minneapolis … enough that you’re going to have to be smart with traveling," said FOX Weather Meteorologist Britta Merwin. "It’s all about knowing what you’re going to be driving through on Tuesday into Tuesday night."
