While the center of attention will be on the risk of strong tornadoes over parts of the Plains into Tuesday night, the risk of severe weather will continue Wednesday over the Mississippi Valley.
During Wednesday and Wednesday night, the risk to lives and property will continue with lesser impact ranging from power outages and downed trees to travel disruptions and foiled activities.
There is the potential for thunderstorms with damaging wind gusts, large hail and flash flooding from central Indiana, southwestward to the upper Texas coast Wednesday.
Cities in the path of the severe thunderstorms during the day and early evening hours Wednesday include Indianapolis, Peoria, Ill., St. Louis, Paducah, Ky., Memphis, Little Rock, Ark., Greenville, Miss., Shreveport, La., and Houston.
During the overnight hours Wednesday, the storms will continue to march eastward at increasing forward speed. The storms are likely to reach from Ohio to southern Alabama, southern Mississippi and southeastern Louisiana.
During Thursday and Thursday night, strong to locally severe thunderstorms are likely to affect the central and southern Appalachians and Piedmont areas to as far south as northern Florida.
It is possible that downpours and thunderstorms could affect activities during activities at the 2013 Masters Tournament at Augusta, Ga., Thursday afternoon into Friday morning.
The thunderstorms that have the potential to bring tornadoes and very large hail to the Plains Tuesday will organize into a solid line of thunderstorms by Wednesday. The weather community refers to this as a squall line.
While the risk of tornadoes is somewhat lower this day, there could still be a few brief tornadoes produced in the strongest storms along and ahead of the line.
