s="...SUMMARY...
   Severe thunderstorms are most likely across north-central/northeast
   Texas and the Ark-La-Tex region during the late afternoon and
   evening. Destructive hail and wind, along with a few tornadoes are
   possible. Severe thunderstorms are also expected across the
   Mid-South and Ohio Valley.
 
   ...North-central/northeast TX and southeast OK/ArkLaTex...
   In the wake of a decaying MCS across the Lower Mississippi River
   Valley, a northwestward-extending outflow boundary will continue to
   modify/drift northward with rapid/strong destabilization this
   afternoon particularly along and south of it. A quick
   reestablishment of lower/some middle 70s F surface dewpoints will
   occur into prior-MCS-impacted areas, with MLCAPE in excess of 4000
   J/kg expected for parts of north-central/northeast Texas into far
   southeast Oklahoma and the nearby ArkLaTex. Special 19Z observed
   soundings are expected from Fort Worth/Shreveport to help better
   gauge/confirm this destabilization trend and the degree of capping."
