A strong upper level low pressure system that settled over Northern Mexico became stationary over the ArkLaTex region from March 8- March 12, 2016. This system alone produced over 500% more than average monthly rainfall in the state of Louisiana. The strong El Nino contributed to a stronger than normal Aleutian Low. A cutoff low funneled flooding precipitation into the Lower Mississippi Valley. Rainfall amounts of over 20 inches were recorded in some locations. Many locations in northern Louisiana experienced extreme flooding; from this, many historical records were broken. Most lakes and rivers matched or exceeded record crest marks. This analysis goal is to provide an overview of the synoptic aspects of the storm, and provide more insight into the consequential effects of the flood event.
