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...Today and tonight.

Scattered to numerous thunderstorms are expected by late afternoon
into the evening and overnight hours as a strong cold front shifts
into the region. Some storms may be strong to severe with damaging
winds and hail possible, along with a non-zero tornado threat that
cannot be completely ruled out.

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

Additional thunderstorms will be possible through the remainder of
the weekend into much of next week as the cold front will stall near
the coast and lift back northward Monday as a warm front. Meanwhile,
multiple upper level disturbances will transition across the region
through mid week and bring locally heavy rainfall with some storms.
These periods of heavy rainfall may present some possible flooding
concerns through the middle of next week with total event rainfall
amounts generally expected to range between 3-6 inches along with
isolated totals possible.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel, amateur radio
operators, and storm spotters may be needed today and tonight.
