Episode Narrative During the late afternoon and evening hours of Easter Sunday, a large and strong upper level low clashed into an air mass where high levels of moisture were being pulled northward. This resulted in scattered severe storms which produced penny to half dollar sized hail and damaging winds. Most of the hail occurred across NW portions of the forecast area while the damaging winds occurred across the southern third. All of the convective wind damage occurred within the Highway 84 corridor from Natchez to Laurel as a bowing line of storms moved through this area and downed numerous trees. Some of the winds were as high as 70 or 80 mph across portions of Lincoln, Lawrence, Jefferson Davis, and Covington Counties. In addition to the damaging winds and hail, heavy rain and substantial flash flooding occurred. The heaviest rains fell along and south of the Highway 84 corridor from Brookhaven to Laurel where 4 to 6 inches fell with a few select locations likely reaching 7 inches.

Aside from the convective winds, which occurred from the line of thunderstorms, a wake low wind event occurred across the northeast portion of the forecast area (locations E of I-55 and N of I-20). This wake low occurred as higher surface pressures were held on to by the stratiform rain shield. As the back edge of the rain pushed east, surface pressures are allowed to drop rapidly in response to the main surface low which was located over southern Arkansas. The rapid drop in pressure, forced the winds to increase and shift more out of the east. As this occurred, sustained easterly winds increased to 30 to 45 mph with gusts between 50 and 60 mph. These strong winds downed many trees and caused other minor damage across the northeast portion of the area.
Event Narrative Numerous roads were flooded in Hattiesburg, which almost flooded some homes. Numerous roads were flooded in the northern portion of the county around Highway 42. Several roads were washed out as well across the northern sections. Rainfall totals ranged from 4 to 6 inches.
