Wider weather episode

During the late afternoon hours on July 24th, strong to severe thunderstorms developed across southeastern Illinois and southwestern Indiana ahead of a surface cold front located immediately to the northwest. Ahead of the cold front, temperatures across southwestern Indiana surged into the low-to-mid 90s during the afternoon on the 24th, with dewpoints residing in the mid-70s. This allowed for 3000-4000 J/kg of mixed-layer CAPE, leading to explosive convective development during the mid-to-late afternoon hours. By the time storms entered south central Indiana, decreased insolation reduced instability somewhat; however, storms were still strong enough to produce isolated wind damage across Dubois and Crawford County. As the cold front's forward progress had nearly stalled, the moist unstable air mass persisted over southern Indiana into the early overnight hours, leading to continued elevated convection which contributed to isolated flash flooding issues.
