.DISCUSSION...
A weak tropical wave/upper level trough will provide support for scattered
showers and thunderstorms each afternoon through Sunday. These storms will
be capable of periods of torrential downpours and frequent lightning. Storms
will also be capable of producing outflow boundaries that could result in
short lived, but rapid, changes in wind speed and direction. Away from storms,
light southerly winds will prevail today through the weekend. As discussed on
the phone, an updated forecast that includes more detailed information for Sunday
may be requested Saturday.
