   Valid 221200Z - 231200Z

   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM NORTHWEST
   TEXAS INTO MISSOURI...

   ...SUMMARY...
   Isolated severe thunderstorms are possible on Sunday from northwest
   Texas to central Missouri.

   ...Southern Plains to Missouri...

   An upper trough over the central/southern Rockies Sunday morning
   will track east over the central/southern Plains. Around 40-50 kt
   southwesterly flow will overspread northwest TX into KS/OK and MO
   ahead of this feature. At the surface, A cold front will develop
   southeast across the Mid-MS Valley to southern Plains. Convection
   may be ongoing across portions of the central/southern Plains to the
   Mid-MS Valley Sunday morning, resulting in some uncertainty in
   airmass destabilization through peak heating. Nevertheless, a
   seasonally moist airmass and favorable vertical shear will support
   organized thunderstorm clusters during the afternoon/evening ahead
   of the advancing cold front. Some risk for damaging gusts will
   accompany this activity from northwest TX into central MO.
