The derecho developed just east of Omaha, Nebraska in the late evening hours of July 4. The storm raced east at 60 mph (100 km/h) as it passed through eastern Indiana and northwest Ohio by 8 a.m. on July 5. It continued east and dissipated over the Delmarva Bay area in the early evening hours that same day.
Six people were killed and 67 were injured.
This derecho event was similar to several other windstorms that occurred throughout the summer of 1980. Like the summer of 1998, a strong high-pressure ridge sat over the central and southern Plains creating a massive heat wave and drought. The bow echo systems were kept north and east of the high-pressure ridge and moved southeast. The Heat Wave of 1980 is among the billion-dollar disasters listed by NOAA.
