This Hazardous Weather Outlook is for portions of south central
Arkansas, southwest Arkansas, north central Louisiana, northwest
Louisiana, southeast Oklahoma, east Texas and northeast Texas.

.DAY ONE...This Afternoon and Tonight...

Showers and thunderstorms will increase across much of East
Texas, Southeast Oklahoma, Southwest Arkansas, and Western
Louisiana this afternoon, ahead of a strong upper level storm
system that will slowly shift east across Oklahoma. A warm front
will begin to move north into East Texas, north Louisiana, and
possibly extreme southern Arkansas late this afternoon and
evening, with showers and thunderstorms expected to intensify near
and south of this boundary where weak instability interacts with
moderate wind shear and large scale forcing ahead of this storm
system. This may yield isolated strong to severe thunderstorms
tonight over East Texas and portions of North Louisiana, with
damaging winds and marginally severe hail possible. However, the
primary threat will be locally heavy rainfall, as widespread
rainfall amounts of one to three inches areawide, with isolated
higher amounts. This may result in minor flooding of low lying,
poor drainage areas, before the showers and thunderstorms diminish
from west to east late tonight.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

Showers and isolated thunderstorms will diminish across southcentral
Arkansas and northcentral Louisiana Sunday morning as this storm
system shifts east across Arkansas into northern Mississippi.
Scattered showers and isolated thunderstorms will return to the
region Wednesday and Friday, near and ahead of a couple of cold
frontal passages that will move through the area. However, no
hazardous weather is expected at this time.


Activation of emergency managers, spotter networks, and amateur
radio operators, may be needed tonight for isolated severe
thunderstorms and the potential for minor flooding.
