Earlier this week there were two events that could be classified as a derecho. Both were just west and south of the Grand Rapids area. We did get a good Thunderstorm and a lot of rain from the 1st one and less lightning are less rain from the 2nd one. Here is some information on derechos in general. Derechos can cause extensive damage, with wind speeds rivaling some tornadoes In the Midwest summer is full of all sorts of weather events, but few pack as much destructive power. A derecho can cause wind speeds of over 100MPH. Damage can be almost as severe as a tornado. And they cover a much larger area than a tornado. According to NWS data, derechos are most common between May and July, when nearly two-thirds of the events have historically occurred. Derechos develop with a “bow echo.” Thunderstorms experience a phenomenon called “updrafts” early in their formation, when warm surface air rises until condensation begins forming, ultimately transitioning to rain. This forces cool air toward the ground on the back end of a storm, which has the effect of generating strong winds near the ground. As the line of storms strengthens, updrafts continue on the edge of the storm and the mass of rain-cooled air at the surface expands the storm horizontally, pushing it forward more quickly and generating higher wind speeds. In certain instances, those winds sustain for hundreds of miles. Derechos can and have happened Michigan here are 3 of the bigger ones in Michigan. July 16, 1980: This derecho moved through extreme Southern Michigan. July 13, 1995: This derecho moved across Upper Michigan and Lower Michigan, causing millions of dollars in damage, three deaths, and several injuries. In Roscommon County alone, 100,000 trees and 100 miles of power lines were blown down. May 31, 1998: This derecho hit West Michigan, causing an average speed of 70 mph and winds of up to 130 mph. The storm killed four people, injured 146, and caused an estimated $172 million in damage. The Federal Emergency Managers Association declared 13 counties a Federal Disaster Area.
