COMET Case Study 012: Gravity Waves and the Palm Sunday Tornadic Outbreak (27 March 1994) Data at UCAR/JOSS/NOAA/CODIAC

Abstract: This case spans the tornadic outbreak on Palm Sunday (27 March 1994)
in Alabama. Gravity waves were triggered with deep convection that
developed in northeastern Texas. The waves modulated mesolows that
developed along a cold front and acted to force the severe convection
in Alabama.

This event was one of the Significant Weather Events of 1994 and
resulted in 20 deaths, 320 injuries, and $107 million in damages.
