NOTES ON THE WEATHER FOR WESTERN AUSTRALIA
Issued at 4:55am WST on Saturday the 4th of July 2009

SYNOPTIC SITUATION AND FORECAST EXPLANATION:
A high pressure ridge lies over central parts of the SW Land Division, with a
mid level cloud band extending from the Pilbara through the Gascoyne,
Goldfields, southern Interior and into northeastern parts of the Central Wheat
Belt. Isolated showers are expected with the cloud band. The cloud band will
contract eastwards during the day and clear the west Pilbara and west Gascoyne
by during the morning and lie over the Interior, Eucla, eastern Southeast
Coastal district and adjacent Goldfields by the evening. Fine weather will
continue through the remainder of the state.

FUTURE DEVELOPMENTS:
On Sunday the mid level showers should clear the east of the Southeast Coastal
district during the morning and become confined to the eastern Eucla and
southeast Interior by Sunday evening. Fine weather is forecast for the remainder
of the state, until some isolated showers develop about the Southwest district
towards evening as a cold front approaches. 
On Monday a cold front will move across the SW Land Division, expected to be
near the SW Capes about sunrise, moving eastwards to lie over eastern parts of
the SW Land Division, SW Gascoyne and western Goldfields by the evening.
Widespread showers are expected with the front, tending more scattered in
eastern inland areas. Some moderate to heavy falls are possible about western
districts. Isolated showers will persist in the onshore stream in the wake of
the front.
On Tuesday a weak ridge of high pressure will develop in the wake of the front
with isolated showers about southern parts of the Central West, Lower West,
Southwest and adjacent South coastal districts. Isolated showers are also
expected over the far west Pilbara, Gascoyne, northern Goldfields, Eucla and
southern Interior.
