A semi stationary front across the plains over a three day period remained the focus for thunderstorm development on June 11th. The thunderstorms developed initially on the high plains and spread east and intensified producing several large hail events and an isolated tornado in western Nebraska. Overnight as the low level jet strengthened storms continued producing heavy rainfall over already saturated grounds that led to flash flooding.
