concerning taf sites ktul/krvs/kbvo/kmlc/kxna/kfyv/kfsm/krog.
Mainly VFR conditions will prevail through the forecast period.
Some patchy fog may develop tonight, with kbvo most likely to see
reduced visibilities. An isolated shower or thunderstorm cannot be
ruled out, especially at the Arkansas sites, but the chances are
too low to include in the taf's, except at kfsm early this
morning.
