.DISCUSSION...High temperatures will be a few degrees above
average today and tomorrow with dry conditions for most locations.
Monsoonal moisture begins to move into the area starting Tuesday,
and thunderstorm chances are expected to last through the end of
the week. Cannot rule out a few isolated dry thunderstorms, but
moisture should be sufficient to produce wetting rains with most
activity. Light winds are expected away from any outflows.
Note: Thunderstorms imply gusty and erratic winds.
Note: Please see operating plan for detailed zone descriptions at:
