Area Forecast Discussion National Weather Service Norman OK 610 PM CDT Wed Oct 19 2016 .DISCUSSION... Please see the 00Z aviation discussion below. && .AVIATION... A cold front will continue to push southward this evening. A few showers and storms are trying to develop near OUN, LAW, and SPS right now. However, storm coverage should remain fairly low near OUN and LAW so will only include VCTS there. Over SPS, storm coverage should increase dramatically over the next 2-3 hours so a tempo group has been included there. Otherwise, expect some gusts to around 20 to 25 kt from the north behind the front with some VFR cigs around 040-050. && .PRELIMINARY POINT TEMPS/POPS...
