Showers and thunderstorms will increase late this afternoon through tonight across Northeast Texas, Southeast Oklahoma, Southwest Arkansas, and portions of North Louisiana, north of a stationary front over Southeast Texas and Central Louisiana, and ahead of an approaching upper level disturbance. Given the extent of instability aloft, isolated strong to severe thunderstorms will be possible over these areas, capable of producing large hail and possibly locally gusty winds. Locally heavy rainfall will also be possible as well where these storms move repeatedly over the same areas, which may result in minor flooding of low lying, poor drainage areas. .DAYS TWO THROUGH SEVEN...Friday through Wednesday... Showers and thunderstorms will be ongoing Friday morning across portions of Southern Arkansas, East Texas, and North Louisiana, before diminishing from west to east during the day with the departure of the upper level disturbance. An isolated strong to severe thunderstorm can not be ruled out Friday morning over these areas, capable of producing large hail and locally gusty winds, before these threat diminish for the afternoon. Isolated to scattered showers and a few thunderstorms may redevelop along and north of the front as it drifts north into portions of Lower East Texas and North Louisiana Friday night, before the front lifts back north as a warm front out of the region Saturday. Additional showers and thunderstorms will increase across the region Sunday afternoon through Tuesday as a cold front gradually shifts back southeast through the area. The threat for isolated strong to severe thunderstorms and locally heavy rainfall can not be ruled out across the region during this timeframe, before drier conditions settle in by Wednesday. .SPOTTER INFORMATION STATEMENT... Activation of emergency management personnel...amateur radio operators...and storm spotters may be needed tonight for portions of Northeast Texas, extreme Southeast Oklahoma, Southwest Arkansas, and extreme Northern Louisiana. 15
