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

.DAY ONE...This afternoon and tonight.

Strong to severe thunderstorms will begin to develop this afternoon
across much of the Four-State region and become more widespread this
evening into the overnight hours. Some of these storms could produce
large hail and damaging thunderstorm wind gusts. While conditions are
not conducive for a widespread tornado outbreak, isolated tornadoes
cannot be ruled out. In addition to the severe weather threat will be
an excessive heavy rainfall threat this afternoon through overnight
across much of the region. That excessive heavy rainfall threat will
shift farther south and east into more of North Central and Northeast
Louisiana the first half of Friday. Low-lying and poor drainage flood
prone areas will be the most susceptible to flash flooding late today
through tonight and into early Friday.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.

While showers and thunderstorms will be possible across portions of
the Four-State Region next week, atmospheric instability does not
appear significant enough or the development of strong to severe
thunderstorms at this time.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will most likely be needed this afternoon into the
evening and overnight hours for the threat of severe thunderstorms.
