Mar 18, 2008
Very heavy rain began developing late on the 17th in northern and western Arkansas, and continued on the 18th as a powerful storm system approached from Texas. The system dredged copious moisture from the Gulf of Mexico, and sent it toward Arkansas with a deep southerly wind flow. Well above normal precipitable water was noted, which enhanced rainfall efficiency across the region.
