No. 173: Rawinsonde released from Barksdale AFB at 1500 CST. Shreveport under influence of very tight low of a local nature which extended through the 500 mb. level. In all probability, rawinsonde balloon path was circular following isobar curvature around Shreveport, hence balloon was seen approximately two hours later in the same area.
