Weather hazards expected... Limited Hail risk. Limited Thunderstorm wind damage risk. Limited Flooding risk. Significant Lightning risk. DISCUSSION... Scattered showers and thunderstorms will impact far southern Missouri generally south of Highway 60 into this evening. A localized strong to marginally severe storm will be possible with the strongest storms and be capable of producing hail to the size of nickels and wind gust to 50 mph. After activity diminishes tonight, showers and thunderstorms will spread back over far southern Missouri and extreme southeastern Kansas late tonight into early Friday morning. This activity could produce heavy rainfall which may result in localized flooding. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. Periods of heavy showers and a few thunderstorms will impact the outlook area Friday and Friday night before tapering off Saturday evening. Storm total rainfall will generally range from 2 to 4 inches with locally higher amounts possible across far southern Missouri. Rainfall of this magnitude over a large area has the potential to produce flooding in flood prone and poor drainage areas and low water crossings. Flooding of larger main stem rivers may also develop. A Flood Watch is in effect for southern Missouri and far southeastern Kansas late tonight through Friday night. There is a limited risk for strong to locally severe storms Friday across far southern Missouri near the Arkansas border if enough instability can develop. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed through tonight. && 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 Hatch
