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.

Showers and thunderstorms will continue across much of the area this
afternoon. A Marginal Risk (Level 1/5) for severe weather remains
in place for our nearly the entire Four State Region, save for our
southwesternmost zones of deep east Texas. Damaging winds and large
hail look to be the primary associated hazard with these storms.

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

The next organized severe weather threat will develop on Saturday,
with areas along and north of the I-30 corridor included in a
Marginal Risk (Level 1/5) and our extreme northern zones in a Slight
Risk (Level 2/5). Damaging winds and hail look to be the primary
associated hazards with these storms, as well as brief periods of
heavy rainfall. Thunderstorm chances continue on a near-daily basis
through the course of the coming week, with the best chances for
stronger storms being across the northern and eastern zones of the
CWA, into southwest Arkansas and parts of north & central Louisiana.

Temperatures are on track to climb back into the mid to upper 90s
late this weekend and into next week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed.
