Father's Day Storms Will Pierce Midwest, Missouri Valley

UPDATED By WeatherBug Meteorologist, Chad Merrill
The same weather system that walloped the Central Plains and Front Range with severe weather on Saturday will bring fresh severe storms to the Missouri Valley and Midwest today. Parts of the Upper Midwest will have to be on guard for more storms from a new storm system moving in on Monday.
The focal point for the afternoon storminess is a cold front stretched from Iowa to northern Texas with low pressure along its northern flank. As the cold front pushes cooler, drier air into warm, moist air ahead of it, more thunderstorms will erupt from southern Wisconsin to northern Oklahoma.
Milwaukee, Chicago, St. Louis, Tulsa, Okla., and Springfield, Ill., are most at risk for a thunderstorm containing wind gusts in excess of 57 mph and hail larger than 1 inch in diameter. The greatest risk for a tornado is northern Oklahoma into central Missouri.
Just as one cold front clears the Plains, another on its heels in the Northwest today will dart into the Northern Plains for Monday. Warm, moist air surging north ahead of the cold front will prime the atmosphere for evening thunderstorms in the Upper Midwest. While much of the day will be rain-free, after dinner time, quickly developing thunderstorms could produce a few tornadoes and large hail in cities such as Sioux Falls, S.D., Norfolk, Neb., and Des Moines, Iowa.
The storm system making a beeline for the Missouri Valley had a history of producing destructive hail, gusty winds and a few tornadoes in the Central Plains on Saturday. Grapefruit sized hail gutted Hastings, Neb., and Wheeler, Kan., while an 86 mph wind gust ripped through Wall, S.D., with many reports of gusts exceeding 60 mph in central Kansas and southern Nebraska.
