   Mesoscale Discussion 1088
   NWS Storm Prediction Center Norman OK
   0343 PM CDT Thu Jul 19 2018

   Areas affected...Central North Dakota...north-central South Dakota

   Concerning...Severe potential...Watch unlikely 

   Valid 192043Z - 192245Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Storm coverage is expected to increase this afternoon and
   early evening. Isolated strong to severe wind gusts and large hail
   are possible. A WW is not anticipated, but convective trends will be

   DISCUSSION...An approaching shortwave trough will foster development
   of scattered strong to severe storms across the discussion area.
   With 30 kts of of mid-level flow, per KBIS VAD profile, and
   relatively cold temperatures aloft with a mid-level thermal trough,
   multicell storms should be capable of isolated instances of severe
   wind gusts and perhaps some large hail. With the loss of daytime
   heating and upstream mid-level ridging increasing during the
   evening, activity should wane after a few hours. The overall spatial
   extent of the threat is expected to remain isolated. A WW is not
   expected, however, convective trends will be monitored.
