.DISCUSSION...
A disturbance of monsoonal moisture will allow relative humidity
values to remain above 20 percent through Sunday, and winds will
remain light enough to keep fire weather headlines out of the
picture. However, isolated showers and thunderstorms are
expected this evening through Saturday afternoon. Erratic winds
are possible near any thunderstorms.
