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

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

No hazardous weather is expected.

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

An upper level trough will approach the Four State Region from the
west late on Monday with showers and thunderstorms accompanying
this trough. Excessive heavy rainfall will begin affecting
portions of the Middle Red River Valley of Northeast Texas,
Southeast Oklahoma and Southwest Arkansas as early as Monday Night
but especially on Tuesday. This heavy rain threat will progress
slowly south and east, encompassing the remainder of the Four
State Region Tuesday Night, Wednesday and Wednesday Night before
exiting the region on Thursday. Flooding could become widespread
across portions of the region, especially where we see training
of thunderstorms Tuesday through Wednesday Night. Flash Flood
Watches will likely become necessary for portions of the Four
State Region as early as Monday Night but especially Tuesday
through at least Wednesday Night.

In addition to the heavy rainfall threat, there will be a threat
of strong to severe thunderstorms across portions of the region as
well Tuesday through Wednesday with damaging wind gusts, large
hail and isolated tornadoes also possible.


Activation of emergency management personnel...amateur radio
operators...and storm spotters will not be needed.
