Overview

A line of intense thunderstorms brought 70-90+ mph winds and widespread damage to portions of southeast Nebraska and southwest Iowa including the Omaha and Lincoln areas. Despite the widespread wind damage, this line of storms did not meet the criteria to be classified as a derecho. A derecho wind damage swath must extend either continuously or intermittently more than 400 miles (about 650 km) with a width of at least 60 miles (about 100 km). This criterion is used to eliminate more common, shorter-lived, and generally less-organized wind-producing convective systems. This particular line of storms produced damage for about 230 miles.
