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...

Isolated thunderstorms will increase over East Texas, Southeast
Oklahoma, and possibly portions of Southwest Arkansas and Western
Louisiana this afternoon, and spread across the remainder of the
region tonight. Brief heavy rainfall will be possible, with
additional shower and isolated thunderstorm redevelopment possible
across Southeast Oklahoma and adjacent Southwest Arkansas late
tonight. A couple of isolated severe thunderstorms are possible
across portions of Southeast Oklahoma and East Texas through this
evening. If any severe storms develop, damaging winds and large
hail will be the primary risks.

.DAYS TWO THROUGH SEVEN...Monday through Saturday...

Showers and thunderstorms will increase across the region Monday
with the passage of an upper level disturbance. Isolated strong to
severe thunderstorms can not be ruled out over East Texas, Southeast
Oklahoma, adjacent sections of Southwest Arkansas, and Western
Louisiana, with locally gusty winds and brief heavy rainfall
possible. Showers and thunderstorms will increase once again
Tuesday afternoon and continue through much of this week, with the
threat for locally heavy rainfall and flash flooding possible
through Thursday over East Texas, Southeast Oklahoma, Southwest
Arkansas, and possibly Western Louisiana. Cumulative rainfall
amounts of three to five inches are possible over these areas,
with isolated higher amounts in excess of eight inches possible,
especially over portions of East Texas. This rainfall will result
in new rises and possible flooding on area creeks and bayous,
rivers and lakes. Isolated severe thunderstorms will be possible
each day as well, with damaging winds the main threat. These
showers and thunderstorms are expected to gradually diminish
across the region by Saturday.
