A clusters of thunderstorms rapidly evolved into a 100 km long squall line. By 1051 UTC, the southern half of the squall line took the shape of a Line Echo Wave Pattern (LEWP). Updrafts were strengthening as evident in increasing radar reflectivities between 3 and 6 km. Between 1057 and 1103 UTC, a significant bowing line segment and associated rear-inflow notch (Przybylinski 1995) developed over northwestern Montgomery County, or just west of the city of Montgomery.
