Weather hazards expected... Limited Tornado risk. Elevated Hail risk. Elevated Thunderstorm wind damage risk. Significant Flooding risk. Significant Lightning risk. DISCUSSION... Multiple rounds of thunderstorms with heavy rain will continue to impact the outlook area the remainder of the afternoon through tonight. Torrential rainfall will continue to train from southwest to northeast across the area which will cause significant flooding to occur. There is an elevated risk for strong to severe storms generally across far south central Missouri. The strongest storms will be capable of producing large hail to the size of golf balls, wind gusts in excess of 60 mph and perhaps an isolated tornado. Flash flooding will be likely, especially south of a Pittsburg Kansas to Lake of the Ozarks line as additional waves of thunderstorms with heavy rain will impact the area through tonight. Additional rainfall amounts of two to four inches of rainfall with embedded higher amounts will be possible. This will lead to extensive flash flooding and moderate to major flooding on most of the rivers and streams in the area. Some record crest levels are even expected. A Flash Flood Watch is in effect for the entire outlook area through Sunday. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Residual flooding will continue Sunday through at least the first half of the workweek next week. There will be an additional risk for showers and a few thunderstorms by mid week next week. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed in the next three hours for areas mainly southeast of a Salem to Gainesville line. && More detailed information can be accessed at: http://www.weather.gov/sgf/sitrep This product in graphical format...along with other weather... hydrological and climate information...at http://www.weather.gov/sgf Lindenberg
