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

.DAY ONE...Today and Tonight...

Scattered showers and thunderstorms will be possible today across
portions of Southeast Oklahoma, Southwest Arkansas, and the
eastern sections of Northcentral Louisiana, as an upper level
disturbance moves across these areas. Isolated strong
thunderstorms can not be ruled out, with locally gusty winds and
brief heavy rainfall possible before diminishing this evening.
However, additional showers and thunderstorms are expected to
develop late tonight over Eastern Oklahoma and Western Arkansas,
which will shift south into Southeast Oklahoma and Southwest
Arkansas. Isolated strong to severe thunderstorms will be possible
with these storms late, with damaging winds and brief heavy
rainfall possible. Given the saturated grounds over Southwest
Arkansas, any prolonged heavy rainfall could result in localized
flash flooding late tonight.

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

Scattered showers and thunderstorms will be possible Friday across
Southeast Oklahoma, Southwest Arkansas, and Northcentral
Louisiana, before diminishing from north to south during the day.
Isolated strong to severe thunderstorms will be possible during
the morning, capable of damaging winds and brief heavy rainfall,
and even localized flash flooding over Southwest Arkansas.
Afterwards, hot and humid conditions are expected this weekend,
with heat indices near or exceeding 105 degrees. Isolated showers
and thunderstorms will be possible over Southwest Arkansas and
Northcentral Louisiana Friday through Monday, before a weak
surface front moves through the region late Sunday through Monday.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel...amateur radio
operators...and storm spotters may be needed today and tonight for
any isolated strong or severe thunderstorms that may develop. Please
relay any information about observed severe weather to the NWS
while following all local, state, and CDC guidelines.
