   The severe weather threat for Severe Thunderstorm Watch 337

   SUMMARY...A complex of thunderstorms will continue pushing
   south/southeast this evening, with some ongoing threat of damaging
   winds and perhaps marginally severe hail. The overall intensity
   trend should be downward through the overnight hours, but there may
   be some lingering potential for stronger gusts into the early
   morning hours.

   DISCUSSION...A bowing complex of thunderstorms, with a mature
   trailing stratiform region, is advancing across northeast Oklahoma
   late this evening. Surface observations within the trailing region
   depict pressure rises of about 2-3 mb/hr, suggesting outflow will
   further surge southeast through the overnight. Rich boundary-layer
   moisture ahead of the line has ensured only modest nocturnal cooling
   so far, such that an increase in convective inhibition has been
   slow. Thus, while storm cores will likely weaken some, becoming
   progressively displaced from the surging outflow, a threat of gusty
   damaging winds may persist. Additionally, warm-air advection related
   to the low-level jet may foster additional development along the
   western/upwind flank of the complex. These cells may also pose a
   threat of marginally severe hail and locally damaging winds through
   the early overnight hours.
