Weather influences

• On the 1st a high pressure system over south-eastern Australia shifted slowly eastwards and started to weaken. This high extended a relatively dry air mass over most of the state.
• The high pressure system extended a weakening ridge over the state on the 2nd. This brought a stable air mass across most of the state.
• The high pressure system started to move out into the Tasman Sea on the 3rd and extend a ridge that weakened across the state. This extended a stable air mass across the state.
• On the 4th a weak ridge of high pressure over eastern Queensland continued to weaken while shifting offshore, which produced fine and settled conditions over most of the state.
• The ridge of high pressure on the 5th shifted out into the western Coral Sea and weakened further as the high pressure system shifts further offshore.
• On the 6th a strong upper level low pressure system over the South Australia/ Northern Territory border shifted eastwards along with an associated cold front approaching western Queensland with a ridge over eastern Queensland clearing northward and offshore.
• A strong upper level low pressure system shifted eastwards on the 7th into north-west New South Wales while tracking south-eastwards. This approached eastern Queensland later in the day and brought moist and unstable conditions with showers and thunderstorms over southern and eastern parts of the state.
• The cold front shifted eastwards over southern and eastern parts of the state while weakening on the 8th before clearing off the east coast in the afternoon. A new ridge of high pressure developed in the wake of the trough which extended a cool and dry air mass. The front extended to a low pressure system shifting eastwards over South Australia that extended a cool and dry air flow.
• On the 9th a high pressure system in the Great Australian Bight shifted eastwards and extended a ridge northwards over central Queensland and combined with a low pressure system moving into the Tasman Sea to extend a cool and dry air mass over most of the state.
• A high pressure system on the 10th over south-east Australia extended a weak ridge over the state and combined with a low pressure system shifting eastwards into the Tasman Sea to extend a cool and dry south to south-westerly flow across the state.
• On the 11th and 12th high pressure system in the Tasman Sea slowly shifted eastwards and extended a weak ridge of high pressure over the state. This continued to bring a dry and stable air mass over the state. Some showers on the exposed southern Queensland coast in weak onshore flow on the 11th.
• The high pressure system in the Coral Sea extended a weak ridge over the state on the 13th and continued to extend a dry and stable air mass over the state.
• On the 14th the high pressure ridge contracted northwards into the north of the state. A significant cold front over the west shifted eastwards and approached a trough further east, but resulting instability remained to the west of the region.
• A significant cold front shifted eastward over the state on the 15th, clearing the southern Queensland coast early in the evening while contracting offshore. This brought showers and thunderstorms over the region and the adjacent inland. A high pressure system over South Australia extended a ridge following the passage of the front.
• On the 16th a trough shifted further offshore with fine weather throughout the state. A weak high pressure system over south-western Queensland shifted eastwards and extended a dry and stable air mass throughout the state.
• The high pressure system shifted eastwards over southern Queensland extending a dry and stable air mass over most of the state on the 17th.
• On the 18th the high pressure system shifted eastwards over eastern Queensland and then moved offshore, which continued to bring a dry and stable air mass. A trough moved eastwards over the state and extended a warm and dry air mass with its passage.
• The trough continued to shift eastwards over the state on the 19th before another trough shifted eastwards over the east later in the day. Warm air shifted eastwards ahead of the trough and dry westerly flow followed the troughs over the south.
• On the 20th the trough contracted into northern and central parts of the state. Dry west to south-westerly flow over the south following the passage of the trough.
• On the 21st a high pressure system south of Western Australia and over central Australia extended a ridge over the state with stable conditions. A weak trough shifted eastwards over the state. These combined with a complex low pressure system over south-eastern Australia to extend dry westerly flow over southern and central parts of the state
• A high pressure system moved east into the Great Australian Bight on the 22nd and extended a strengthening ridge over the state. The system combined with a complex low pressure system over the southern Tasman Sea to direct a dry south to south-westerly flow over the state with cool conditions over central and southern areas of the state
• The high pressure system moved into South Australia on the 23rd and extended a strengthening ridge of the east Queensland coast. This ridge combined with a complex low pressure system shifting eastwards over the Tasman Sea to direct a dry south-westerly flow over the state with cool conditions over southern and central parts of the state.
• The ridge continued to remain in place on the 24th and 25th with a resulting stable air mass as a high pressure system remained in place over southern Australia on the 24th and moved into south-eastern Australia on the 25th
• A large high pressure system shifted eastwards over inland New South Wales on the 26th and extended a firm ridge along the east Queensland coast. Stable conditions throughout except for the odd shower along the southern Queensland coastline.
• On the 27th the high pressure system moved east and into the Tasman Sea as another high pressure system moved into the Great Australian Bight. This maintained a firm ridge along the Queensland east coast with settled conditions in the region
• The high pressure system moved through south-eastern Australia on the 28th and maintained a firm ridge along the east Queensland coast. This extended moist onshore flow along the east Queensland coast but with fine weather over the region. A weak trough moved through the region during the day
• The high pressure system moved through new South Wales on the 29th before shifting into the Tasman Sea and maintained a firm ridge along the east Queensland coast, with stable conditions.
• The high pressure system shifted further east on the 30th with the ridge along the east Queensland coast weakening, with stable conditions remaining
• On the 31st the high pressure system extended a weakening ridge over the east coast as the high pressure system shifted further east off the east coast. A weak trough moved through the east in the afternoon, before clearing south-eastern Queensland later in the afternoon before contracting further northwards. This brought warm and dry conditions.
