Some of the storms will be strong to severe, with large hail, damaging winds and a few tornadoes possible. Later this evening and into Sunday morning, the potential for strong to severe storms will continue, as a cold front moves through the state. These thunderstorms could also become severe, with damaging winds possible with the strongest storms as this activity looks to form into a larger, more organized line or complex. Large hail and a few brief tornadoes will also be possible as this line or complex moves southward through much of Arkansas Sunday morning. Locally heavy rain will also be possible, resulting in an isolated flash flood threat. .DAYS TWO THROUGH SEVEN...Sunday through Friday Sunday morning, the threat for seeing severe weather will have decreased, but the cold front will still be dropping south across the state. Additional thunderstorms will be possible Sunday afternoon and evening across the southeast half of the state as the cold front pushes through this region of Arkansas. Additional strong to severe thunderstorms may again be possible during this period. Calmer and drier conditions will be seen for Monday into Tuesday. The threat for hazardous weather will then become low. .Spotter Information Statement... Spotter activation may be needed tonight and early Sunday. && Visit NWS Little Rock on the web.
