Rains soak southern Plains after suspected tornado touchdown in Texas

Heavy rains threatened to inundate sections of the central and southern Plains Tuesday -- a day after a suspected tornado from the same slow-moving system touched down in south-central Texas. The National Weather Service has issued a flash flood watch for sections of Texas, Louisiana, Oklahoma and Arkansas. Severe thunderstorms are forecast across much of the same area. By Wednesday morning, accumulations up to 10 inches of rain are expected in northeast Texas and southeast Oklahoma, up to 8 inches in southwest Arkansas, with 4 to 5 inches being common across the rest of the watch area, forecasters said.
