   Valid 281200Z - 291200Z

   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM NORTHEAST TX
   INTO PARTS OF THE MID/UPPER MS VALLEY...

   ...SUMMARY...
   Strong to potentially severe thunderstorms will be possible Sunday
   across a broad area from northeast Texas into parts of the upper
   Mississippi Valley. Large hail, damaging winds, and a couple
   tornadoes will all be possible.

   ...Northeast TX into parts of the upper MS Valley...
   A broad region of at least some severe potential is expected on
   Sunday from northeast TX into parts of the upper MS Valley.
   Uncertainty remains high due to the influence of extensive
   antecedent convection leading into the D3/Sunday period. 

   A negatively tilted shortwave trough and attendant surface low are
   forecast to move from the central Plains toward the upper MS Valley
   on Sunday. Extensive convection will likely be ongoing at the start
   of the period from Texas toward the lower MO Valley, and potentially
   farther north into parts of the upper Midwest. Some lingering severe
   threat could accompany this morning convection, especially toward
   the ArkLaTex region where somewhat more favorable
   moisture/instability will be in place. 

   Widespread cloudiness/convection across much of the warm sector will
   tend to limit diurnal destabilization, though deep-layer shear will
   remain favorable for organized storms, and some
   heating/destabilization will be possible in the wake of morning
   convection. 

   One area of potential redevelopment will be immediately ahead of the
   ejecting shortwave trough from eastern KS into western MO and
   southern IA, where a few stronger cells/clusters could pose a threat
   of hail, isolated damaging gusts, and perhaps a tornado. 

   Vigorous redevelopment will also be possible along the
   western/southern periphery of persistent convection near the
   ArkLaTex region, where rich moisture and favorable wind profiles
   could support at least an isolated threat for all severe hazards.
   Some threat could linger into Sunday night across this area,
   potentially aided by an upstream low-amplitude shortwave trough that
   will be approaching the southern Plains.
