   Areas affected...Eastern/South-Central SD...Central NE

   Concerning...Severe potential...Watch likely 

   Valid 082016Z - 082245Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Thunderstorm development expected later this afternoon. At
   least scattered storm coverage is anticipated, with some storms
   capable of large hail and damaging downburst winds.

   DISCUSSION...Surface analysis and visible satellite imagery reveals
   a somewhat complex pattern across eastern SD into central NE over
   the past hour so. A cold front continues to move slowly eastward
   into eastern SD. This front gradually transitions to a stationary
   front across central NE. Increasing dewpoints have been noted near
   this stationary front (at LBF, TIF, and ANW in central NE) over the
   past hour or so. Mesoanalysis suggests the most of warm sector
   south/southeast of these boundaries has destabilized. Some more
   vertically developed cumulus has been noted recently in visible
   satellite imagery.

   Strong buoyancy as well as convergence along this boundary and
   within the warm sector is expected to result in convective
   initiation later this afternoon. Mid-level temperatures are slightly
   warmer here than areas farther north, which could limit storm
   coverage. Additionally, this area is on the southern edge of the
   stronger flow aloft, resulting in slightly less vertical shear. Even
   with some of these limitations, at least scattered storm coverage is
   anticipated and the robust buoyancy will still support intense
   updrafts capable of large hail and damaging downburst winds.
