   Concerning...Tornado Watch 176...

   The severe weather threat for Tornado Watch 176 continues.

   SUMMARY...Thunderstorm clusters will propagate east this evening.
   Some risk for a brief tornado, or hail/wind gusts can be expected.

   DISCUSSION...Remnants of a long-lived MCV are tracking into
   northeast OK early this evening. This feature appears to be
   weakening within a broader corridor of convection that is now
   spreading across eastern OK into western AR. Scattered supercells
   have been common along the southern fringe of this complex of
   storms, enhanced by low-level warm advection along the northern-most
   extent of higher buoyancy. Latest MRMS data suggests hail is common
   with the strongest updrafts, especially over southern Little River
   County AR. With the LLJ expected to increase across the southern
   High Plains later this evening, MCV may continue to weaken as it
   progresses into northwest AR. Until then, the greatest risk for
   severe storms will be across southwest Arkansas.
