March 2008 Flood Event Review
A large upper trough with a closed upper low slowly moved east across the Central United States March 17th through the 19th. This allowed a strong southerly flow to transport copious amounts of moisture from the deep south into the Midwest.  Several waves of low pressure moved along a nearly stationary frontal boundary that remained just south of the forecast area, across northern Arkansas and extreme southern Illinois. Several rounds of rain and thunderstorms brought locally heavy rainfall to much of the forecast area, with the greatest amounts confined along and south of Interstate 44 in Missouri and Interstate 70 in Illinois. Total rainfall ranged from less than an inch across portions of west central Illinois to almost 10 inches in southern Reynolds County, Missouri. The excessive rainfall led to flash flooding of low lying areas and major flooding on local rivers and creeks for the next week. Many people were affected by this event, with millions of dollars in damage recorded across the forecast area.
