Wider weather episode

A strong nocturnal low-level jet interacting with a nearly stationary frontal boundary triggered a Mesoscale Convective System (MCS) over northern Missouri during the pre-dawn hours of June 17th. The large thunderstorm cluster tracked east-southeastward along the boundary, producing significant wind damage and flash flooding. The storms were focused along and southeast of a Rushville...to Springfield...to Shelbyville...to Robinson line. Numerous trees and power lines were blown down. In addition, very heavy rainfall of 3 to 5 inches along and south of a Jacksonville to Effingham line created pockets of flash flooding.
