This Hazardous Weather Outlook is for portions of southwest
Arkansas and southeast Oklahoma.

.DAY ONE...Today and Tonight...

Isolated showers and thunderstorms will be possible this afternoon
over Southeast Oklahoma and the northern sections of Southwest
Arkansas, as a warm front lifts north across these areas. Showers
and thunderstorms may become more scattered tonight over the
areas, interacting with increasing instability and upper level
disturbances moving northeast atop the front. Isolated severe
thunderstorms will be possible, with large hail and damaging winds
possible, with the severe threat diminishing late.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday...

Showers and thunderstorms will increase across Southeast Oklahoma
and Southwest Arkansas Saturday afternoon and night, along and
ahead of a slow moving cold front that will approach the area late and
associated upper level storm system that will drift east into West
Texas and Oklahoma. Given the strong wind shear and instability
ahead of the front, some storms may become severe, with large
hail, damaging winds, and isolated tornadoes possible. There is
also an enhanced threat for locally heavy rainfall, which may
result in flash flooding as these storms develop and move slowly
and repeatedly over the same areas. Widespread rainfall amounts
of three to five inches with isolated higher amounts are
possible, before the showers and thunderstorms diminish by
daybreak Sunday. Additional scattered showers and thunderstorms
are possible Wednesday with the passage of a cold front.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency managers, spotter networks, and amateur
radio operators, may be needed this evening over Southeast
Oklahoma.

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

.DAY ONE...Today and Tonight...

Isolated showers and thunderstorms will be possible tonight over
portions of extreme Northeast Texas and extreme Southern Arkansas,
but hazardous weather is not expected. However, a tight pressure
gradient will result in southerly winds increasing to 15 to 20
mph with gusts to 30 to 35 mph late this morning, persisting
through the afternoon and overnight.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday...

Scattered showers and thunderstorms will be possible across East
Texas, extreme Southern Arkansas, and North Louisiana Saturday
afternoon, as an upper level disturbance lifts northeast across
the area. Given the extent of wind shear and instability expected
to be in place, isolated severe thunderstorms can not be ruled
out, with large hail and damaging winds possible. However, the
severe weather threat will increase Saturday night as showers and
thunderstorms increase along and ahead of a slow moving cold
front that will approach the area late and associated upper level
storm system that will drift east into West Texas and Oklahoma.
Some of these storms may become severe, with large hail, damaging
winds, and isolated tornadoes possible. Locally heavy rainfall
will also be possible in the stronger slow moving storms, which
may result in minor flooding of low lying, poor drainage
areas, with rainfall amounts ranging from one to three inches.
Additional scattered showers and thunderstorms are possible
Wednesday with the passage of a cold front.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency managers, spotter networks, and amateur
radio operators, should not be needed today or tonight.
