Environment

A vigorous low pressure system moving through Nebraska brought the necessary ingredients together for a severe weather outbreak across the region. In the mid levels of the atmosphere (15,000-20,000 ft above the ground), strong winds and cold temperatures overspread a warm, moist air mass streaming north from the Gulf of Mexico to create the necessary instability and vertical wind shear for severe thunderstorm development. The supercells that produced the tornadoes across eastern Nebraska and southwest Iowa developed along a Pacific front that extended south from an area of low pressure that moved from central into northeast Nebraska during the day.
