A low-pressure system formed over southern British Columbia on June 23 and  moved southeastward into Montana. Storm fronts coming from this system and another one out of California began to fully form into thunderstorms, heavy rain and hail over Nebraska and Minnesota on June 25. By late on June 26, a weak warm front became draped over the Central Plains stretching from southeastern Colorado northeastward through Kansas to northern Missouri. This became the focal point for two early morning tornadoes in central part of Kansas, including a violent and deadly F4 tornado in Wakeeney. Meanwhile, a low-pressure system formed over southern Minnesota on June 24 while another one formed over northeastern  Illinois northwest of Chicago on June 26. These systems moved eastward across the Great Lakes and Northeastern United States producing multiple rounds of severe weather here and in the Mid-Atlantic. Non-tornadic effects.
