This Hazardous Weather Outlook is for portions of the Missouri Ozarks and extreme southeast Kansas. .DAY ONE...Today and Tonight. Weather hazards expected... Elevated tornado risk. Elevated hail risk. Elevated thunderstorm wind damage risk. Elevated flooding risk. Significant lightning risk. DISCUSSION... A few strong to severe thunderstorms are possible this morning generally west of the Highway 39 corridor. Large hail up to the size of quarters and wind gusts in excess of 50 mph could evolve with a few of the most intense storms. A second round of thunderstorms will be possible this afternoon and evening. These storms could be more robust and capable of producing large hail to the size of golf balls and wind gusts in excess of 60 mph. A tornado or two will be possible, particularly across southern Missouri this afternoon and this evening. Given the wet soil conditions combined with elevated streamflows, widespread rainfall will likely lead to flash flooding in some areas. Low water crossings and low lying roads next to flashy streams will have the greatest risk of flooding today and tonight. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday. Thunderstorm chances will increase Monday and Tuesday of next work week. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed this afternoon and evening over all of extreme southeast Kansas and the Missouri Ozarks. && 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 Cramer
