Growing Severe Risk For Upper Midwest. Strong to severe T-storms are expected to mushroom along a vigorous warm frontal boundary forecast to push northward through midweek. For Minnesota the best chance of hail, damaging straight-line winds and even a few isolated tornadoes will come Tuesday afternoon/evening. It's a mixed blessing: welcome rain from showers and T-storms, but a few violent storms can't be ruled out as the atmosphere shifts gears from mid-March to a truly May-like pattern of temperature and humidity.

After an EF5 tornado struck this Midwestern city on May 22, 2011, duct tape was added to the remaining letters of the school’s sign to read “HOPE.” The tornado destroyed four schools and damaged five, but the schools worked to offer summer school classes the following month and have the school year start on Aug. 17.
