...FLOOD WATCH IN EFFECT FROM 7 AM CDT THIS MORNING THROUGH THURSDAY
MORNING...

This Hazardous Weather Outlook is for southwest Arkansas, southeast
Oklahoma and northeast Texas.

.DAY ONE...Today and tonight.

Scattered to numerous showers and thunderstorms are expected to
develop today across portions of Northeast Texas, Southeast Oklahoma,
and Southwest Arkansas. Locally heavy rainfall will be possible,
which may result in localized flooding of low lying, poor drainage
areas. Additional showers and thunderstorms will track through the
region late this evening and overnight, which will result in a
renewed threat for locally heavy rainfall and localized flooding
before diminishing late. Locally gusty winds will also be possible
from these storms as well.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.

Showers and thunderstorms will shift to the southeast and diminish
across the region Thursday morning. Much cooler and drier air will
begin to filter south Friday, and especially for the upcoming
weekend. A slow warming trend will commence Monday, but dry
conditions will continue.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed today and tonight for the potential
for rainfall and flooding reports, as well as gusty winds associated
with the storms late this evening and overnight.
