A few strong to severe thunderstorms are possible. Damaging wind gusts would be the primary concern with any severe thunderstorms, though there is also a smaller hail and tornado threat. Due to a high amount of moisture in the atmosphere, and the tendency of storms to form and move over the same areas, stronger storms will also be capable of producing heavy rainfall. This could lead to localized flooding issues, particularly in portions of western, north central, and southeast Arkansas that have seen several inches of rain in the last 24 hours. Storms are expected to diminish during the evening hours. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday No additional hazardous weather is expected at this time. .Spotter Information Statement... Spotter activation could be needed over eastern or southeast Arkansas today. && Visit NWS Little Rock on the web. Go to http://weather.gov/lzk. 57
