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

.DAY ONE...Tonight...

...A Flash Flood Watch is in effect through 6 am Thursday
Morning...
Scattered showers and thunderstorms will become numerous overnight
across portions of the region. Periods of excessive heavy rainfall
associated with a very slow moving frontal boundary may result in
areas of flash flooding as training of showers and thunderstorms
will likely occur over the watch area. Rainfall totals of 3-6
inches of rainfall expected. Some isolated higher amounts are
possible.

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

Persistent southwest flow aloft will provide 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.

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

.DAY ONE...Tonight...

Scattered showers and thunderstorms will be possible overnight but
the more widespread rainfall will likely hold off across the
region until the day Wednesday.

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

As a cold front moves slowly south and east into the region during
the day Wednesday, showers and thunderstorms will become numerous
with two to four inches of rainfall possible during the day
Wednesday into Wednesday Night. Persistent southwest flow aloft
and south winds at the surface will remain over the Four-State
Region providing ensuing moisture and disturbances resulting in an
unsettled and wet weather pattern through the end of the week and
into the weekend. As soils become saturated, the potential for
flooding and flash flooding will likely increase across the region
as we go through the remainder of the work week.

.SPOTTER INFORMATION STATEMENT...

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