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

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

Scattered showers and thunderstorms will continue to develop and
move into the area with a chance for storms to become severe
during the late afternoon and into the evening. Main threats other
than heavy rainfall and possible flash flooding will be high and
damaging winds and an isolated tornado. A lake wind advisory will
remain in effect until 6 PM CST that will produce Southerly winds
of 15-25 MPH with higher gusts to 30-35 MPH. A cold front will be
entering Southeast Oklahoma and parts of Southwest Arkansas , and
Northeast Texas around and after midnight which should help the
showers and thunderstorms to form into a linear band. Rainfall
amounts of three to five inches will be possible with higher
amounts to six inches.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday...

Persistent Southwest flow aloft providing ensuing
moisture and disturbances resulting in an unsettled and wet
weather pattern through the week and into the weekend. Adding to
the mix will be the South winds at the surface over the southern
half of the Four-State Region to the Southeast of the frontal
boundary that will be sending moisture over the boundary. Moderate
to heavy rainfall will continue into Wednesday and Wednesday
night. The cold front will become nearly stationary and remain a
focus for thunderstorms. As soils become saturated, the potential
for flooding and flash flooding becomes moderate for the northwest
sections of the forecast area. Later in the week, moderate to
heavy rainfall will be shifting eastward across the region thus
maintaining the potential for flooding.

.SPOTTER INFORMATION STATEMENT...

Emergency management personnel...amateur radio operators...and
storm spotters may be needed tonight through late Wednesday.
