  • Storm time medium-scale traveling ionospheric disturbances occur regularly near the base of storm-enhanced density in the continental US
  • Disturbance wavefronts developed primarily during storm main phase at evening–midnight local times, elongated NW-SE, and traveled southwestward
  • Disturbance onset coincided with intense electric fields and zonal propagation was synchronized with enhanced westward thermospheric winds
