It will be a very busy day for severe weather across portions of the Plains and Midwest. The SPC has issued a moderate risk for severe weather for portions of Missouri, Iowa, Nebraska, and Kansas. Outside the moderate risk, a slight risk extends from the Hill Country of Texas to the western Great Lakes. This is a very serious and dangerous situation for these parts of the country. The SPC is paying very close attention to this, as they are expecting a severe weather outbreak with numerous tornadoes possible and very large and damaging hail, greater than two inches in diameter. In the upper-levels, a trough will be moving out of the Rockies and will be providing, as well as enhancing the dynamics over the affected regions. At the surface, uplift will be provided by a cold front moving south from the Northern Plains, and a warm front will be lifting north. The warm front is bringing an influx of moisture and very warm air into the region. There
will also be ample wind shear which will support very strong updrafts and enhance rotation. All these ingredients are coming together and setting the stage for a very volatile atmosphere. There will be ongoing showers and storms during the morning and early afternoon. As daytime heating maxes out during the mid to late afternoon, discrete supercells are forecast to develop. These cells will reach severe limits rapidly because of the very unstable atmosphere. Once the storms develop, they will persist into the overnight hours. All modes of severe weather are expected including the threat of damaging winds and flash flooding, but once again the threat for numerous tornadoes and very large hail are the main concerns. If you are in these areas, stay weather aware and make sure you have multiple reliable sources for severe weather notifications. Follow us on Twitter. Like us on Facebook.
