Severe thunderstorms will ignite from western Texas to Minnesota and Wisconsin on Saturday with elevated violent storm risks centered on Nebraska and portions of Colorado, Iowa and Kansas.
Cities at risk for dangerous weather conditions Saturday into Saturday night include Omaha, Nebraska; Sioux Falls, South Dakota; Des Moines, Iowa; and Wichita, Kansas. Severe storms may reach part of the metro areas of Denver and Minneapolis as well.
The threat of severe weather on Saturday is higher than what has occurred elsewhere across the nation this week.
The storms could threaten Saturday afternoon and evening play at the 2014 College World Series in Omaha.
As with any thunderstorm, lightning will pose the greatest danger to those outdoors.
During this particular event, winds from the storms may not only bring risks to high profile vehicles but also may down trees and power lines. Hail may be large enough to break windows, destroy crops and damage roofs. Enough rain may fall to cause incidents of flash flooding.
The first stages of severe thunderstorm development Saturday could also yield isolated tornadoes in parts of Nebraska, northeastern Colorado, southeastern South Dakota and southwestern Minnesota.
According to AccuWeather Meteorologist Scott Breit, "We think separate severe thunderstorms on Saturday over Nebraska are likely to grow together quickly, form a large complex of storms and transform into a large hail and damaging wind event."
Breit is concerned that some of the tornadoes may be concealed by heavy rain.
This complex of storms will begin to bow eastward and southward Saturday night across Nebraska, Iowa, northern Kansas, southern Minnesota and southwestern Wisconsin.
"There will also be isolated tornadoes developing farther south late Saturday afternoon and evening along a boundary of dry air and moist air extending into western and central Kansas," Breit said.
Isolated strong to severe thunderstorms will extend into the Oklahoma Panhandle and western Texas.
On Father's Day, the risk of severe weather will extend farther east. Thunderstorms on Sunday will extend from eastern Minnesota, Wisconsin and the Upper Peninsula of Michigan to Illinois, Missouri, southeastern Kansas and part of Oklahoma.
Cities that could be impacted by the storms at some point on Sunday include Minneapolis, Milwaukee, Chicago, St. Louis, Oklahoma City and Kansas City, Missouri.
"The storms on Sunday will bring threats from large hail and damaging wind gusts," Breit said.
People who plan on being outdoors either camping, fishing or at ballgames in areas threatened by storms are encouraged to keep an eye on the weather and be alert for rapidly changing conditions. Seek shelter as storms approach.
On a positive note, the rainfall over the Plains will continue to chip away at long-term drought. Favorable weather this spring is assisting in the growth of the corn crop.
As the 2015 college football season gets underway, summertime warmth could lead to uncomfortable games across the Ohio Valley and South while storms roll across the Southeast and Upper Midwest.

Tropical Storm Kevin developed several hundred miles southwest of Mexico and is expected to strengthen slowly as it moves northward through Thursday.
A stormy weather pattern will prevail through September across much of southern South America.
While lulls in tropical activity in the Atlantic will continue, a rapid end to the hurricane season in September does not always occur during an El Nino.
Heat will be erased by an autumnlike air mass across parts of northern Europe.
