SYNOPTIC SITUATION AND FORECAST EXPLANATION:

A weak cold front brushed the south coast early this morning with a weak ridge
over southern parts of the state. Isolated coastal showers between Bremer Bay
and Israelite Bay in the onshore airstream.  

On Tuesday the high pressure ridge will strengthen to the southwest of the state
with another cold front moving along the south coast late in the day. Isolated
showers over the South Coastal and southern half of the South East Coastal
districts, extending into southern parts of the Southwest district during the
afternoon and evening and along the Eucla coast late evening.    

On Wednesday, the cold front will lie over far southeastern parts of the state
in the early morning with isolated showers over the South Coastal, South East
Coastal, adjacent Great Southern, adjacent Goldfields and Eucla at first.
Showers expected to contract east and clear the SW Land Division, Goldfields and

Interior for a period during the day. A middle level disturbance moving over far
southeastern parts of the state may also bring isolated thunderstorms over the
far east of the South East Coastal district and southern Eucla, contracting east
and clearing during the day. Fresh and gusty E/SE winds over northern parts of
the state as a high pressure system begins to move south of the state in the

By Thursday, the high pressure system will lie near the south coast with
isolated showers over far eastern parts of the South East Coastal district and
Eucla in the onshore airflow contracting to coastal parts by the early
