.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.
