What Is Bow Echo?
A line of storms on radar that bulges out in the middle like an archer's bow. The bulge is where the strongest straight-line winds usually are. In technical terms: A bow-shaped radar echo, roughly 20-200 km long, produced by a rear-inflow jet descending to the surface behind the apex; associated with damaging straight-line winds at the apex and bookend vortices, including brief tornadoes, on the flanks (especially the north end).
