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...
Southerly winds persisted across the Four-State Region this
morning, resulting in the maintenance of low level moisture. The
atmosphere will become very unstable across the Middle Red River
Valley of northeast Texas, southeast Oklahoma, and southwest
Arkansas late this afternoon through this evening. An approaching
upper level trough from the Southern Plains and the impingement of
a cold front will likely generate strong to severe thunderstorms
across the aforementioned areas this evening into the overnight
hours of early Sunday morning. Large hail, damaging wind gusts,
and a tornado or two will be possible along with locally heavy
rainfall. During Sunday, the entire Four-State Region sees the
possibility of seeing strong to severe thunderstorms along and
ahead of a southeastward moving cold front as well.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...
The cold front will be progressing southeastward across the Four-
State Region, interacting with a warm, moist and unstable
atmosphere and resulting in the development of scattered
thunderstorms. Some of these thunderstorms will become strong to
severe with large hail and damaging wind gusts being the primary
threats. The unsettled weather pattern will continue through next
week as the cold front returns to the region as a warm front,
which will advect in a warm and moist airmass. As a result,
isolated to scattered showers and thunderstorms will be possible
next week, though the potential for widespread hazardous weather
will be low.

.SPOTTER INFORMATION STATEMENT...

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