   Areas affected...Parts of east central Arkansas

   Concerning...Severe Thunderstorm Watch 109...

   Valid 120455Z - 120700Z

   The severe weather threat for Severe Thunderstorm Watch 109
   continues.

   SUMMARY...A couple of strong storms persist, with some lingering
   risk for hail into the 1-2 AM time frame.

   DISCUSSION...Thunderstorm intensities have generally been weakening
   the past hour or so, but a few stronger cores persist along the
   western flank of a lingering convective cluster rooted within a zone
   of enhanced lower/mid tropospheric warm advection.  One or two of
   these, near and east-southeast of Searcy toward the Memphis area,
   continue to occasionally produce at least small to marginally severe
   hail.  This probably will continue to gradually diminish during the
   next couple of hours, as short wave ridging builds northeastward. 
   After 06-07Z, the primary warm advection driven storms may become
   focused near the crest of this ridging, across the Missouri Bootheel
   vicinity into parts of western Kentucky and Tennessee, but it is not
   clear that destabilization will become supportive of an appreciable
   increase in potential for severe hail.
