   Areas affected...eastern Oklahoma...northern Arkansas...and
   southern-east-central Missouri

   Concerning...Severe potential...Watch unlikely 

   Valid 042053Z - 042230Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Scattered strong thunderstorms are possible this afternoon
   and evening from eastern Oklahoma across northern Arkansas and into

   DISCUSSION...Scattered thunderstorms have developed along and ahead
   of a cold front from eastern Oklahoma into northwest Arkansas and
   into Missouri. The airmass ahead of this cold front is moderately
   unstable with MLCAPE around 1500 to 2000 J/kg. Effective shear is
   relatively weak (<30 knots per SPC mesoanalysis), but VWPs closer to
   the cold front (INX and SGF) are sampling greater 0-6 km shear
   between 25 and 30 knots. This, in addition to low-level convergence,
   will support more robust updrafts near the cold front. A few strong
   to isolated severe storms will be possible this afternoon. However,
   height rises and broad synoptic scale subsidence should preclude a 
   more organized severe weather threat and the need for a watch.
