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
   monitored.

   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.
