   Concerning...Severe Thunderstorm Watch 247...

   The severe weather threat for Severe Thunderstorm Watch 247
   continues.

   SUMMARY...A severe threat is expected to continue through late
   tonight from far eastern Oklahoma into northwest Arkansas and
   southwest Missouri. Wind damage and a tornado threat will be
   possible along the leading edge of a squall-line. Weather watch
   issuance may become necessary to the east of WW 247.

   DISCUSSION...The latest radar imagery shows a linear MCS over
   northeastern Oklahoma in the southeast portion of WW 247. The linear
   MCS is associated with a rear inflow jet which is supporting a wind
   damage threat along the leading edge of the line. In addition, the
   Tulsa WSR-88D VWP shows a looped hodograph with a 0-3 km storm
   relative helicity of 325 m2/s2. For this reason, a tornado threat
   could also continue with the line as it moves eastward into northern
   Arkansas. Although the severe threat may become more isolated with
   time, weather watch issuance can not be ruled out at this time.
