A progressive upper level disturbance, paired with the support from a maximum jetstream wind flow, trekked across the Four Corners region and resulted in numerous showers and thunderstorms. While these storms moved quickly they were still very efficient rainfall producers which led to localized heavy runoff and at least two flash floods where thunderstorms trained behind one another.
