Three ,derechos, struck the Ozarks, Ohio, and Tennessee valleys June 2017 Northern Plains Derecho: June 11, 2017: During the morning hours of June 11, 2017, a dangerous derecho tracked eastward out of South Dakota, across Southern and Central Minnesota, and through Northern Wisconsin into the Upper Peninsula of Michigan.
Derechos, are almost always caused by a type of weather system known as a bow echo, which has the shape of an archer’s bow on radar images. These in turn are a specific type of mesoscale convective system, a term that describes large, organized groupings of storms.
Derechos, can form during any time of the year, but they're most common during the summer months when the air is extremely hot, very moist, and instability is abundant. The worst ,derechos, tend to form between June and August during or right at the end of a blockbuster heatwave.
Derechos, are high-impact events; they are one area where society would benefit greatly from increased meteorological knowledge. BAMS: What was the biggest challenge you encountered in your work to update the derecho definition? SC: Having thoughts on introducing any new idea is one thing, but putting those concepts into words is another.
