This Hazardous Weather Outlook is for south central Arkansas,

Higher chances for strong to severe thunderstorms return today as a
stronger disturbance moves through the region. Damaging winds will be
the greatest threat, but large hail can't be ruled out. Heavy rain
from these thunderstorms can boost the potential for a flash flooding
threat through tonight.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

Another round of damaging wind gusts will be possible on Sunday, as
a cold front moves into the region. Showers and thunderstorms remain
in the forecast for portions of the region each of the following days
until late next week, along with some of the warmest temperatures of
the year. Afternoon highs could approach the mid to upper 90s by the
middle of next week.

.SPOTTER INFORMATION STATEMENT...
