Forecast issued at 4:40 am EST on Thursday 28 August 2014.
A complex low pressure system lies offshore over the far southern Coral Sea and is expected to shift south into the Tasman Sea during today. A second low centre lies near the southeastern Queensland border over water and is expected to intensify during today. The complex low system is expected to move towards the New South Wales coast during Friday, and move eastwards away from the coast on Saturday. A weakening surface trough lies through the southeast of the state and is expected to contract offshore during this morning. A slow moving high in the southern Tasman sea will maintain a ridge through western and northern Queensland through the remainder of this week.
Forecast for the rest of Thursday
A Severe Weather Warning for Damaging Winds and Dangerous Surf is current for Southeast Queensland and Queensland waters south of Sandy Cape. Scattered showers and rain areas clearing off the far southeast coast by about dawn. Otherwise, isolated showers about the southeast coast, becoming less likely during the afternoon and evening. Fine and mostly sunny conditions expected elsewhere. Gale force southerly winds and a powerful southeasterly swell over southern Queensland waters. Mostly moderate south to southeasterly winds elsewhere
Fire Danger - Very High over the Gulf Country, North Tropical Coast and Southeast.
Friday 29 August
An upper low and a complex low pressure system lying over the northern Tasman Sea are likely to move southwest towards the central New South Wales coast. Elsewhere a ridge extending from a high east of New Zealand will strengthen and dominate the weather over Queensland. Fine and sunny conditions expected across much of Queensland, with just the chance of some isolated showers over the exposed coast and islands of southeastern Queensland and also about the central and tropical coasts. Powerful surf conditions are likely for southeast Queensland waters, and are expected to ease during the afternoon. Early frosts are again possible through the southern central interior.
Saturday 30 August
The upper low and the surface low are expected to move eastwards away from the east Australian coast. The ridge will maintain fine and sunny conditions across most of Queensland, with only isolated light showers possible about tropical coast in a weak onshore flow. Early frosts are again possible about the southern and central interior of the state.
Sunday 31 August
A high will drift slowly eastwards over southeast Queensland, maintaining a ridge along the tropical east coast. This will lead to fine and sunny conditions across much of the state, with only isolated light showers possible about the tropical coast in a weak onshore flow.
Monday until Wednesday
The high will drift slowly to the east, extending a ridge along the tropical east coast. This will lead to fine and sunny conditions across much of the state, with only isolated light showers possible about the tropical coast in a weak onshore flow. A weak surface trough is expected to push into southwestern Queensland during Monday and cross the south of the state on Tuesday and offshore by Wednesday. The airmass ahead of this feature should be too dry to support any precipitation, although isolated showers about the southern border cannot be totally ruled out. Early frosts will persist until Monday about the southern and central interior of the state due to a dry airmass. Daytime temperatures will increase on Monday and Tuesday across the interior and south due to west to northwesterly winds, then fall once more following the passage of the trough.
The next routine forecast will be issued at 4:30 pm EST Thursday.
