Although organized severe storms are not expected, a few storms may briefly pulse up to produce damaging winds to go along with torrential rainfall and frequent lightning. These storms may reach just east of the Mississippi River, possibly impacting adjacent portions of southern Illinois and west Kentucky. Most of this activity should be done by 5 PM. Outside of the thunderstorms and their outflows, heat indices over southeast Missouri, southern Illinois and far west Kentucky will range from 100 to 105 this afternoon. .DAYS TWO THROUGH SEVEN...Monday through Saturday Isolated afternoon thunderstorms are forecast for part of southeast Missouri and southwest Illinois on Monday. These storms should remain below severe limits. Heat index values will top out again near 100 degrees mainly during the afternoon hours on Monday across southeast Missouri and southern Illinois. Scattered to numerous thunderstorms are forecast Tuesday through early Wednesday morning. These thunderstorms are expected to move slowly southeast in a broken line through the outlook area. Some of the storms will likely become severe late Tuesday afternoon and evening, with damaging winds the primary hazard, followed by isolated large hail. Heavy rain will be a greater hazard during the evening hours. The Storm Prediction Center has issued a Slight Risk of Severe Thunderstorms for Tuesday and Tuesday night, extending from Benton Illinois and the Land Between the Lakes northeast into parts of southeast Illinois, southwest Indiana, and the Pennyrile region of west Kentucky. A Marginal risk of severe thunderstorms covers the remainder of the outlook area Tuesday and Tuesday night. .SPOTTER INFORMATION STATEMENT... Spotters over southeast Missouri should be prepared for activation this afternoon. Activation may be requested throughout the area Tuesday afternoon and evening. DRS
