Showers and thunderstorms are expected to increase later this morning through the afternoon across Lower East Texas, much of North Louisiana, and Southcentral Arkansas, near a surface boundary progressing southeast into these areas from a decaying complex of showers and thunderstorms early this morning. Strong daytime heating within a very moist air mass in place will contribute to strong instability this afternoon, such that some of these storms may become severe near and south of Interstate 20 across Lower East Texas and North Louisiana, with damaging winds and locally heavy rainfall possible. While these storms should push out of the area late this afternoon, additional showers and thunderstorms are expected to redevelop by late afternoon through this evening over portions of North Texas and Southern Oklahoma, which should gradually progress east southeast into Southeast Oklahoma, Northeast Texas, and adjacent sections of Southwest Arkansas later tonight. There will be the potential for at least isolated severe thunderstorms with damaging winds to develop over these areas tonight, with the threat for locally heavy rainfall and localized flash flooding. .DAYS TWO THROUGH SEVEN...Monday through Saturday... Showers and thunderstorms will increase once again across the region Monday, as an upper level trough slowly progresses east across the area. An isolated severe thunderstorm threat can not be ruled out Monday, with damaging winds and locally heavy rainfall possible. Localized flash flooding will be possible as well where storms producing heavy rainfall continue to move repeatedly over the same areas. While these showers and thunderstorms should diminish Monday night, additional scattered showers and thunderstorms will be possible across the region Tuesday and Wednesday, with some of the stronger storms producing locally gusty winds and brief heavy rainfall. The approach of another upper level disturbance over Oklahoma and the Red River Valley late Wednesday will result in scattered to numerous showers and thunderstorms over portions of extreme Northeast Texas, Southeast Oklahoma, Southwest Arkansas, and portions of the I-20 corridor of North Louisiana Wednesday night and Thursday morning, before diminishing from west to east Thursday afternoon. .SPOTTER INFORMATION STATEMENT... Activation of emergency managers, spotter networks, and amateur radio operators, may be needed later today through tonight across the region. $$ 15
