...Heavy rainfall potential for Thursday through Sunday...
An upper low will move westward across Southeast Louisiana to South
Central Louisiana by Sunday. The low will combine with an
abnormally moist airmass across the region resulting in multiple
days of widespread rainfall. Some heavy rainfall will be noted
during the day on Thursday especially across southern portions of
Mississippi. The heaviest period of rainfall overall will be from
Friday into Saturday. Much of the heavier rainfall will occur during
the heating of the day and into the early evening hours. Rainfall
totals along and south of Interstate 20 will range from 5 to 8
inches with some locally heavier totals amounts possible.
North of Interstate 20 rainfall amounts will range from 2 to 4 inches
with some locally heavier amounts possible.
The biggest concern will be flash flooding associated with some of
the intense heavy periods of rainfall that are possible. The
potential for intense periods of heavy rainfall is possible across
most of the area. Many of the rivers will experience significant
below flood stage rises. Much of the minor river flooding will be
limited to areas along and south of Interstate 20 where antecedent
soil conditions are generally wetter. Some minor river flooding is
possible even across areas north of Interstate 20 wherever intense
heavy rainfall occurs, especially some of the flashier river basins
such as the Big Black River and some tributaries of the Pearl River.
Please stay informed as system evolves over the next 2 to 4 days.
