The cold front that initiated severe weather across central and southern Iowa the previous day stalled mid-way across the state, keeping conditions fairly primed for storms. A weak area of low pressure to the west in the Colorado/Wyoming/Nebraska area developed and initiated in the early evening hours, eventually conglomerating into a potent MCS. By the time it reached Iowa, the strongest areas of the MCS resided across the northern third of the state, producing numerous damage reports and some severe hail. The line weakened through the overnight hours, eventually becoming sub-severe shortly after crossing Interstate 35.
