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...Today and Tonight...

Isolated to scattered showers and thunderstorms will be possible
this afternoon over portions of Deep East Texas, North Louisiana,
and Southcentral Arkansas, near a weak upper level disturbance
that will drift west southwest over these areas. Locally gusty
winds and brief heavy rainfall will be possible with the stronger
storms, before they diminish during the evening with the loss of
heating. In addition, temperatures will climb into the lower and
mid 90s today, and when combined with the humidity, will result in
heat indices ranging from 100 to 105 degrees. Those that must
be outside today should drink plenty of water, wear lightweight,
loose fitting clothing, and take frequent breaks in the shade or
in air conditioned facilities.

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

Isolated to scattered showers and thunderstorms will be possible
over much of the region Monday near the weak upper level
disturbance over Southeast Texas and Central Louisiana, as well as
another upper level disturbance and associated weak cool front
that will enter extreme Northeast Texas and Southwest Arkansas
during the afternoon. These showers and thunderstorms are expected
to continue developing Monday night as the weak front and
associated upper level disturbance slowly shift south across the
region, diminishing from north to south across East Texas and
North Louisiana along and south of the Interstate 20 corridor
Tuesday. Locally gusty winds and brief heavy rainfall will be
possible with the stronger storms Monday through Tuesday morning,
before slightly cooler and drier air spill south behind the front.
Warm and dry conditions will persist for the remainder of the work
week, before isolated to widely scattered showers and
thunderstorms return to portions of Lower East Texas and North
Louisiana Saturday.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel...amateur radio
operators...and storm spotters should not be needed through
tonight.
