Weather influences

• On the 1st a high-pressure system moved offshore into the Tasman Sea and extended a ridge northwards and onshore wind flow along the east Queensland coast
• The ridge along the east Queensland coast remained in place on the 2nd as the high pressure system remained in the Tasman Sea

 

• On the 3rd the ridge decayed as a high pressure system remained over the Tasman Sea. A surface trough and cloud band shifted eastwards reaching the east Queensland late in the day.
• Early on the 4th a surface trough shifted eastwards off the east Queensland coast, allowing a high pressure system in the Great Australian Bight to extend a strengthening ridge over the state. This extended a cool and dry air mass across the state.
• The high pressure system remained in the Great Australian Bight on the 5th and 6th and continued to extend a strengthening ridge and a cool dry air mass across the state.
• On the 7th the high pressure moved to near Tasmania extended a ridge over the state and continued to extend a cool and dry air mass over most of the state.
• The high pressure system moved over south-eastern Australia and into the Tasman Sea on the 8th and extended a ridge along the east Queensland coast and moist onshore wind flow along the east Queensland coast.
• A large high pressure system on the 9th and 10th drifted further eastwards in the Tasman Sea, with an associated ridge starting to weaken along the east Queensland coast. The moist onshore flow however continued to extend along the east Queensland coast
• On the 11th the high pressure system shifted further eastwards with the associated ridge along the east Queensland coast weakening as a consequence. A surface trough shifted eastwards into central districts of the state and extended warm air into east Queensland
• A surface trough and cold front shifted eastwards on the 12th over central and eastern parts of the state clearing the southern Queensland coast in the evening. An upper level trough shifted eastwards over the inland of the state. The proceeding high pressure system and ridge shifted further offshore.
• On the 13th a high pressure system near Tasmania extended a strengthening ridge across the state in the wake of the cold front and surface trough that cleared off the coast. The ridge combined with a deepening low pressure system off the New South Wales coast moving into the Tasman Sea to extend a dry west to south-westerly flow over much of the state. An upper level trough shifted eastwards through the region.
• On the 14th a high pressure system near Tasmania maintained a ridge across the state and combined with a deepening low pressure system slowing eastwards over the Tasman Sea to extend dry and cool west to south-westerly wind flow over southern Queensland.
• A high pressure system to the south of Tasmania on the 15th to 17th maintained a ridge through central Australia and across to the east Queensland coast. This combined with a deep low over the northern Tasman Sea to maintain a cooler and drier air mass over most of the state.
• On the 18th a high pressure system over the south Tasman Sea maintained a weak ridge along the east Queensland coast extending a dry and stable air mass across the state.
• A weak high pressure system on the 19th over southern Queensland extends a weak ridge over the north, light wind flow over the south before a new high pressure system over southern Australia started to extend a new ridge over southern Queensland. This is maintaining a relatively dry air mass and settled conditions over most of the state.
• On the 20th a high pressure system in the Great Australian Bight extended a strengthening ridge across the south. A weak south-westerly wind change moved through the southern Queensland coast as a trough moved off the New South Wales coast. The ridge maintained a stable and dry air mass across the state.
• The high pressure system continued to build over the Great Australian Bight on the 21st continued extending a strengthening ridge over the state. A strong upper level trough moved eastwards over central Australia, moving into western Queensland late in the day, which extended a band of high cloud over much of the state
• On the 22nd the high pressure system shifted slowly eastwards over the Great Australian Bight and continued to extend a ridge over the south of the state. A pronounced upper level trough shifted east wards into central parts of the state. This extended a cloud band over eastern parts of the state but remained outside of the region.
• On the 23rd the high pressure system over south-eastern Australia shifted slowly moved eastwards and extended a ridge across the south of the state. A weakening upper trough shifted eastwards into the region later in the day with resulting rainfall from the instability.
• The ridge over the south on the 24th relaxed as a high pressure system shifted eastwards. A deepening coastal trough and a weak low pressure system started to develop off the southern Queensland coast bringing further unstable conditions.
• On the 25th a high pressure system over the southern Tasman Sea shifted eastwards while the ridge relaxes further over the southern half of the state. A coastal trough deepened along with a weak low moved southward along the southern Queensland coast reaching Sandy Cape late in the day. A surface trough and upper level trough shifted eastwards over the south also, with further rainfall occurring over the region.
• The high pressure system over the south Tasman Sea on the 26th shifted further eastwards relaxing the ridge over the south of the state. A coastal trough and low pressure system continued to shift southwards along the southern Queensland coast in the morning before moving southwards and developed into a significant low pressure system off the central New South Wales coast. In the wake of the trough another trough and an upper level trough moved eastwards clearing the region in the evening with a strong high pressure system building over southern Australia extending a dry air mass in its wake.
• On the 27th a deep low pressure system shifted southwards along the southern Queensland coast. A high pressure system in the Great Australian Bight extended strengthening ridge into the state. The relative dry west- south-westerly flow between these systems lead to settled conditions.
• The deep low pressure system on the 28th slowly moving eastwards off the southern New South Wales coast and started to weaken, whilst the high pressure system shifted northwards into South Australia and extended a ridge into the state. A dry and stable air mass continued to remain in place.
• On the 29th and 30th the high pressure system remained over South Australia and continued to direct a dry and stable air mass into the region
• The high pressure system moved into south-eastern Australia and extended a ridge over the state with a dry and stable air mass remaining in place.
