Remnants of a complex of showers and thunderstorms and an attendant upper level disturbance over Southern and Eastern Oklahoma will trigger scattered showers and thunderstorms this afternoon over portions of Northeast Texas, Southeast Oklahoma, Southwest Arkansas, and North Louisiana, especially as the air mass destabilizes with daytime heating. Isolated strong storms capable of producing gusty winds and brief heavy rainfall will be possible, with minor flooding of low lying, poor drainage areas possible as well in the slow moving storms. Isolated to scattered showers and thunderstorms should continue into this evening before gradually diminishing late. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Scattered showers and thunderstorms will remain possible over much of the region Saturday, as a weak surface front becomes stationary over portions of East Texas and North Louisiana, and weak upper level disturbances aloft traverse the front. Isolated strong storms capable of producing gusty winds and brief heavy rainfall will be possible along the frontal zone Saturday, but the threat for heavy rainfall and flash flooding will increase late Saturday night through Monday as another thunderstorm complex develops and moves east along the front. The front may begin to slowly lift back north late Monday, thus diminishing the heavy rainfall and flood threats. Showers and thunderstorms are expected to become more isolated to widely scattered Tuesday through Thursday, but new rises along the Red and Sulphur Rivers and their tributaries are likely for much of next week. .SPOTTER INFORMATION STATEMENT... Activation of emergency managers, spotter networks, and amateur radio operators, may be needed tonight.
