   Concerning...Severe Thunderstorm Watch 275...277...

   Valid 102102Z - 102230Z

   The severe weather threat for Severe Thunderstorm Watch 275, 277
   continues.

   SUMMARY...A cluster of stronger storms including intermittent
   supercell structures will pose a threat for strong wind gusts and
   isolated large hail across northwestern portions of WW277. Across
   the rest of the watch, isolated severe weather remains possible.

   DISCUSSION...Thunderstorms continue to organize posing a threat for
   severe winds and isolated large hail across WW277. These storms are
   ongoing in a very warm and moist environment characterized by
   surface temperatures and dewpoints in the upper 80s to near 90 and
   low to mid-70s F respectively. Aloft, warmer temperatures have
   limited lapse rates to around 6.5 to 7.5 C/km. While modest, the
   lapse rates and high boundary-layer moisture are maintaining MLCAPE
   of 1500-2000 J/kg. Wind profiles from the KILN VAD show mostly
   unidirectional hodographs with limited shear above 6 km. The
   combination of shear and buoyancy should continue to support
   organized storms in the form of upscale growing clusters and
   intermittent supercells. The main threat is expected to be damaging
   winds given DCAPE values over 1000 J/kg. The moderate buoyancy may
   support isolated large hail, but competing updrafts, and warm 500 mb
   temps near -7 c should keep the threat secondary. 

   A cluster of storms across portions of Auglaize, Shelby, and Logan
   counties will likely pose the most significant threat for damaging
   winds over the next few hours. Storms are forecast to continue
   growing upscale into a squall line through this evening with
   continued potential for damaging winds downstream.
