A westerly flow persists over southern parts of the state, with another cold
front expected move along the south coast later in the day. Isolated showers are

SW Land Division, tending scattered about the southeast coast in the morning.
Showers will contract to the south coast by the afternoon. A band of isolated
showers and thunderstorms are expected in the northeast interior and far
northeast Pilbara.
On Friday a ridge of high pressure will lie just to the south of Perth. Isolated
showers are forecast about south coast parts during the morning, contracting to
the southwest coast during the afternoon. Isolated showers and thunderstorms
should continue through the central interior and southern inland parts of the
Pilbara, reaching the coast in the evening.
On Saturday another cold front will approach the southwest of the state with
isolated showers about west coastal parts extending to southwest of a line
Jurien Bay to Lake Grace in the afternoon. Showers will become scattered near
the south coast in the afternoon and evening. Isolated showers and thunderstorms
will continue through the southwest Pilbara, northeast Gascoyne and the
Interior, tending scattered in the afternoon.
