Jul 4, 2013
A very anomalous pattern set up across the U.S. in early July featuring a persistent upper level trough over and just west of the Mississippi Valley and a downstream ridge off the Mid Atlantic Coast. This brought deep layer moist tropical air into the Southeast for several consecutive days resulting in torrential rains, flash flooding and river flooding. While several episodes of severe weather also occurred during this period, the heavy rain and accompanying flooding were the primary impacts.
