NWS Jackson MS March 21, 2012 Severe Weather and Heavy Rain

Banner

Event Summary

A slow moving storm system combined with abundant moisture to bring nearly 48 hours of rain and thunderstorms to the ArkLaMiss region, beginning the evening of March 20^th and continuing through the afternoon hours March 22^nd. Strong wind shear and forcing from this disturbance and the associated cold front brought severe thunderstorms, tornadoes and widespread flooding. The primary hazards produced by this system were tornadoes and flooding, but there were also many reports of damaging downburst winds. With rich moisture flowing north from the Gulf of Mexico, many of the storms were efficient rain makers that produced both flash flooding and river flooding. Most areas west of the I-55 corridor received 1 to 3 inches, but areas further east along the I-55 corridor received 3 to 4 inches with up to 6 to 8 inches observed for areas east of I-55.
