   Mesoscale Discussion 1075

   0823 PM CDT Sat Jun 17 2017

   Areas affected...Southern into eastern Kansas into western Missouri

   Concerning...Severe Thunderstorm Watch 346...

   Valid 180123Z - 180330Z

   The severe weather threat for Severe Thunderstorm Watch 346
   continues.

   SUMMARY...Severe hail and wind remain possible across the entire
   watch area. Storms are expected to eventually affect far northern
   Oklahoma late this evening, and another watch could be required at
   that time.

   DISCUSSION...Storms continue to fill in along the surface trough
   from near Dodge City northeastward into Missouri. A very unstable
   air mass remains in place with 4000-5000 MLCAPE observed on the 00Z
   DDC and TOP soundings, respectively. Good mid to high level flow
   exists, especially over northeastern portions of the area with the
   upper jet sinking southward. Although low-level flow remains weak, a
   few cells have show midlevel rotation at times, supporting longevity
   and hail size. With time, the main cold front is expected to
   interact with and undercut the existing corridor of storms, with a
   more linear mode expected. Then, a southward drift, which could
   bring locally damaging winds into northern Oklahoma.
