.DISCUSSION...
Drier conditions are expected today with light southerly winds,
but winds may gust to around 20 mph along the coast in the
afternoon as the seabreeze moves inland. Min RH is expected to
fall to 30 to 40 percent for most areas this afternoon. A low
pressure and frontal boundary approach the area on Friday with
higher coverage of showers and better chances for wetting rains
over much of the area.
