.DISCUSSION...
Main concerns today are the timing of a cold front/wind shift at
spot location and another day of hot temperatures.  Currently, showers are
well north of the spot location in northern Oklahoma. At this time, the front
and wind shift is not expected to reach the site until late afternoon and
early evening. This is also the time when widely scattered showers and
thunderstorms may develop and produce strong outflow winds.

A north wind is expected Friday with lingering chances for rain.
