Thunderstorms developed along an outflow boundary in a very moist airmass. Storms were fed by strong low level winds. In addition to aiding buoyancy, these winds also contributed to significant low level wind shear. Some storms produced weak tornadoes and locally heavy rain that led to flash flooding.
