   Mesoscale Discussion 0958
   NWS Storm Prediction Center Norman OK
   0554 AM CDT Sun May 29 2022

   Areas affected...Western/Central IA

   Concerning...Severe potential...Watch possible 

   Valid 291054Z - 291300Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Isolated large hail possible over the next few hours.

   DISCUSSION...Showers and thunderstorms have increased in coverage
   and intensity over the past hour or so across western and central
   IA. This trend will likely continue for the next few hours as the
   low-level jet and associated warm-air advection persist. A
   predominantly multicellular storm mode is anticipated, but steep
   mid-level lapse could still result in a few updrafts strong enough
   to produce hail. Overall severe coverage is uncertain, meriting
   lower watch probability, and convective trends will be monitored
