July 9 - 13, 2012 - Heavy Rainfall and Storm Totals

A weak frontal boundary pushed south into northern Alabama and southern Middle Tennessee on July 9, 2012. This front interacted with a tropical feed of moisture transported north from the Caribbean Sea and produced much needed heavy rainfall through July 13, 2012.  In fact, in many locations in northern Alabama between 2 and 4 inches fell during this time.   In some locations in Lauderdale, Lawrence, and Morgan counties 5 to over 6 inches of rainfall has been reported. Below is an image of rainfall totals for the event beginning at 7 am on July 9th and ending at 7 am on July 13th.
