- The early stage of a severe straight-line wind event and MCS
- W010169Z
- The gust front ahead of this violent storm has blowing dust and scud along it. A strong burst of outflow has just begun, forcing air sharply up to form large flakes or teeth along it where the air rises most rapidly. This is the early stage of what becomes a severe straight-line wind event and MCS (Mesoscale Convective System).
