Flash Flood — Marion, IN

Aug 30, 2022

An upper trough and associated cold front slowly approached central Indiana, focusing the transport of deep moisture into the region. Several rounds of strong thunderstorms impacted much of the area from late afternoon on the 29th into the early morning of the 30th. Mean tropospheric wind as low as 15 knots promoted slow storm motion, which led to locally heavy 1-day rainfall totals and isolated flash flooding from near Terre Haute to the Indianapolis Metro area.
