The Plains and Midwest are bracing for a storm outbreak this week that's likely to include damaging wind, hail and tornadoes. Flash flooding also remains a significant threat.
Yet another system is heading from the Rockies into the Plains by midweek, with greater tornado risks possibly seen as early as Tuesday.
Throughout the next few days, this outbreak of severe weather is expected to deliver massive amounts of rainfall from Texas all the way up into the Great Lakes and Ohio Valley regions, which could see more flash flooding as well -- especially toward the end of the week.
