The same upper level low pressure system that helped to trigger shower and thunderstorm development across the Central Plains Friday night produced widespread heavy rain across the region Saturday and Sunday. This caused extensive river flooding across northeastern Kansas, and ponding of water over roadways and low lying areas across the region. Numerous reports of flooded roadways and homes were received.
