   The severe weather threat for Severe Thunderstorm Watch 397

   SUMMARY...Severe gusts of 70-80 mph and isolated large hail remain
   possible with a southward-moving complex of storms in Severe
   Thunderstorm Watch 397.

   DISCUSSION...Latest radar data from KUEX shows a gradually
   upscale-growing complex of storms tracking southward at around 30-35
   kt across south-central Nebraska. While a consolidated cold pool
   appears to be intensifying, intense/separated supercell structures
   remain evident along/immediately behind the gust front. Given these
   persistent separated supercells and a favorable supercell wind
   profile downstream (upwards of 70 kt of effective shear and a
   large/looping hodograph), instances of large to very large hail up
   to around 2.75 inches remain possible in the near term. However, the
   overall severe risk should be transitioning to a damaging-wind
   threat, owing to the gradual upscale growth. This upscale growth
   should be aided by increasingly orthogonal deep-layer shear to the
   consolidated cold pool and a strengthening southerly low-level jet
   (around 40 kt sampled by downstream VWP). If more robust upscale
   growth does occur, 70-80 mph gusts could become more common.
