   Areas affected...Northeast Oklahoma and Northwest Arkansas

   Concerning...Severe Thunderstorm Watch 331...332...

   Valid 140239Z - 140345Z

   The severe weather threat for Severe Thunderstorm Watch 331, 332
   continues.

   SUMMARY...Bowing line of storms will move into north-central
   Oklahoma this evening, with the risk of damaging winds. A new severe
   thunderstorm watch has just been issued.

   DISCUSSION...A large bowing MCS has evolved across southeast central
   KS, with 50+ knot wind gusts being recently reported at multiple
   ASOS sites.  This activity is expected to surge southeastward across
   north-central and northeast OK along and south of a remnant outflow
   boundary.  Ample CAPE/moisture and increasing mesoscale organization
   of the bow could maintain a severe risk as far east as northwest AR.
