Overnight Severe Weather Threat Looms Across the Great Plains and Midwest in the US
Residents across parts of the Midwest and Great Plains are bracing for an extremely dangerous severe weather outbreak on Monday, just hours after strong storms slammed the region on Sunday. The outbreak is expected to last through Tuesday, bringing the risk of intense EF3 or stronger tornadoes, destructive hail, damaging winds and heavy rain.
Beginning Monday, areas of central and northeastern Kansas into southeastern Nebraska face a rare Level 4 of 5 severe weather threat, with conditions favorable for violent storms capable of producing tornadoes and very large hail.
Central Kansas, extending into Southeast Nebraska, Iowa, Northwest Missouri, and Northern Oklahoma, will be the main area at risk for Monday’s most severe storms. Dangerous weather is expected to continue overnight, with a line of heavy rain and powerful winds forecast to affect at least a dozen states
Sunday’s severe weather outbreak saw storms rapidly develop from Kansas through Nebraska and Iowa into southern Minnesota, bringing hail larger than baseballs and strong tornadoes. Over a dozen tornado reports and more than 100 hail and 150 wind reports were recorded, mainly across eastern Nebraska and western Iowa. The National Weather Service confirmed a strong tornado north of Grand Island in St. Libory, Nebraska, where multiple structures were damaged.
