Weather influences

• A large high pressure system moving eastwards over southern Australia maintained a cool and dry airmass over southern districts of the state in the wake of a trough that cleared off the coast early in the day.
• On the 2nd the large high pressure system drifted eastwards over the Great Australia bight maintaining a cool and dry air mass over most of the state. This combined with a complex low pressure system shifting eastwards over south-east Australia to extend a dry west to south-westerly airflow
• The low pressure system moved out into the Tasman Sea on the 3rd while the large high pressure system in the Great Australian Bight extended a ridge and a cool and dry airmass over most of the state.
• As the high pressure system shifts eastwards on the 4th winds tended onshore along the southern Queensland coast but stable conditions remained over the south
• On the 5th the high pressure system slowly shifted eastwards over south-east Australia maintaining a ridge over southern and central districts of the state and dry and stable airmass. Winds remained onshore along the east Queensland coast but with settled conditions over the region
• The high pressure system shifted eastwards into the western Tasman Sea on the 6th and across the central Tasman Sea on the 7th and 8th maintaining the ridge and a dry air mass over most of the state, with winds remaining onshore along the east Queensland coast
• On the 9th the high pressure ridge decayed over the south of the state as the high pressure system moves further east. This was ahead of the surface trough that shifted eastwards over the interior of the state that brought some instability to the south-east of the state
• On the 10th a trough shifted eastwards over the south-east of the state clearing later in the day and offshore and further northwards in the evening. This extended a cloud band with some instability with its passage
• On the 11th a large high pressure system extended a ridge and onshore winds along the east Queensland coast, with showers confined to the exposed southern and northern east coast of the state. Stable conditions otherwise
• A large high pressure system in south-east Australia on the 12th extended a ridge along the east Queensland coast, with stable conditions over southern Queensland
• On the 13th a weak ridge extends along the east Queensland coast as the high pressure system shifts eastwards in the Tasman Sea. A trough and upper trough over the interior of the state extended a cloud band eastwards across the state with little rain
• A weak ridge continued to extend along the east Queensland coast on the 14th as a high pressure system shifts eastwards over the Tasman Sea. An upper level trough and surface trough shifted eastwards over central and the southern inland parts of the state, reaching the east coast in the evening. A surface trough also deepened in response to the upper level trough.
• A high pressure system shifted eastwards over the southeast Australia and into the Tasman Sea on the 15th that extended a ridge along the east coast with showers along the exposed east coast. Settled conditions otherwise.
• On the 16th a high pressure system in the Tasman Sea slowly shifted eastwards and continued to extend a ridge along the Queensland east coast. This brought showers along the Queensland east coast including the southern coast.
• The ridge strengthened on the 17th as the high pressure system drifted eastwards over the Tasman Sea. This continued to bring some shower activity to the Queensland east coast on the 17th and 18th.
• On the 19th the high pressure system extended a weakening ridge along the east Queensland coast as the high pressure system drifts eastwards over the Tasman Sea. Showers along the east Queensland coast continued in the onshore flow.
• The high pressure system continued to extend a weakening ridge along the east Queensland coast on the 20th maintaining some coastal shower activity of eastern Queensland. A surface trough over the interior of the state brought some instability over central and southern districts with rain areas
• On the 21st a high pressure system near New Zealand extended a weakening ridge along the east Queensland coast. A surface trough shifted eastwards across to the east Queensland coast and mostly cleared the east Queensland coast late in the day under the influence of an upper trough. This brought moisture and unstable conditions with its passage including the south-east of the state. A high pressure system over southern Australia extended a ridge with cool air following the trough
• A large high pressure system over the Great Australian Bight extended a ridge over the southern and central Queensland on the 22nd. A complex low pressure system over the Tasman Sea combined to continue to extend a cold and relatively dry airflow over southern Queensland.
• On the 23rd a large high pressure system combined with a complex low pressure system off the southern New South Wales coast and in the Tasman Sea to extend a cold and relatively dry air mass over the south
• On the 24th to 26th a broad low pressure system remained slow moving over the Tasman Sea, which combined with a large high pressure system in the Tasman Sea to maintain a cool and relatively dry south-westerly flow over most of the state
• A broad area of high pressure over central Australia on the 27th and 28th extended a weak ridge over the south of the state, while a broad low pressure system remained slow mobbing off the New South Wales coast. The combination of these system continued to maintain a cool and relatively dry airmass across the state. A broad upper level trough shifted eastwards across the state with some high cloud but brought stable conditions.
• On the 29th a high pressure system over south-east Australia shifted slowly eastwards, while extending a strengthening ridge and a dry southerly flow over most of the state. Cold air aloft brought some shower activity to the region.
• A high pressure system contracted eastwards into the Tasman Sea and extended a ridge over the east Queensland coast on the 30th. This extended a relatively dry southerly air flow over most of the state, though winds started to tend more onshore along the east Queensland coast with increased moisture.
• On the 31st a high pressure system over New Zealand moved slowly eastwards while extending a weakening ridge over the Queensland east coast. This brought generally stable conditions over most of the state.
