Excessive Rainfall Possible on Friday for the Missouri Valley and South Central US
Widespread thunderstorms are expected from the Missouri Valley, through Arkansas, and into eastern Texas and western Louisiana. Deep moisture in place across this region will allow for thunderstorms producing heavy rainfall. Widespread rainfall accumulations of over one inch can be expected for most of this region, with locally higher amounts in excess of four inches possible in some locations. Given the recent rains in these areas, additional rainfall will aggravate any additional flooding.
