A Severe Thunderstorm Watch will possibly be issued this evening for the Texas Panhandle and South Plains. An upper level storm system is making progress towards the region early this evening. As it approaches we should see thunderstorms begin to develop and increase in coverage tonight. With supportive windshear and an unstable atmosphere some of the storms will likely be severe with large hail and damaging straight-line winds. The severe weather threat could continue into the overnight hours until the storms move east into Oklahoma.
