There was barely a break between the exit of the earlier morning severe convection, and development of the next round during the afternoon and early evening on May 30th across southwest Minnesota.  A series of impulses moved northeast during the day, with a leading strong wave moving out of Nebraska by early afternoon. Storms blossomed near a cold frontal boundary toward the James River Valley, despite the limited diurnal destabilization, due to steep mid-level lapse rates which brought MLCAPE up to 1500-2000J/kg in the warm sector. Strong mid-level winds led to long, linear hodographs. With a warm front also lingering north of Interstate 90, storms that interacted with enhanced low-level shear in the vicinity of various boundaries produced a few brief tornadoes, but strong deep-layer forcing eventually resulted in an evolution toward linear structures with mainly damaging wind.  Near the core of the upper level wave, a secondary band of thunderstorms developed across Nebraska during the late afternoon and raced northeastward through early evening, featuring mainly damaging wind gusts.
