No warnings for Queensland
Forecast issued at 4:31 pm EST on Tuesday 7 July 2015.
A weak high pressure system over South Australia extends a weak ridge into the interior of Queensland with dry and sunny conditions persisting over much of the state during the next couple of days. A ridge along the east coast will be reinforced from Wednesday as a high near Tasmania shifts east into the Tasman Sea. Winds then will tend more moist onshore about the east Queensland coast from Wednesday onwards, with moisture also gradually extending into the central and southern interior late in the week. An upper trough and an associated surface trough are expected to move eastwards across the south of the state from very late on Thursday.
Forecast for the rest of Tuesday
Fine and mostly clear conditions across much of the state. Moderate to fresh southeasterly winds about the east tropical coast and southeast coast. Moderate southeasterly winds in the west, tending southwest to southeasterly over southeastern districts. Light winds elsewhere.
Wednesday 8 July
A slight to medium chance of showers developing in eastern districts, especially about the north tropical coast and exposed parts of the southern and central coasts. Fine and mostly sunny conditions will continue elsewhere. Early frosts are likely over the southern and southeast interior. Moderate to fresh southeasterly winds about the east coast, tending light to moderate southeast to northeast elsewhere in the state.
Thursday 9 July
The high in the Tasman Sea should shift further east whilst maintaining a firm ridge along the east coast of Queensland. An upper trough and associated surface trough will most likely approach the southwest of the state late in the day, resulting in the slight chance of a shower in the southwest. Moist onshore winds will result in the medium chance of showers extending from the central coast into the central interior and Maranoa and Warrego. The slight to medium chance of showers will also occur elsewhere along the east coast. Fine and mostly sunny conditions will continue elsewhere. Early frosts are only a slight chance in the southeast interior due to the increasing moisture.
Friday 10 July
`The high in the Tasman Sea is expected to shift slowly eastwards towards New Zealand, maintaining the ridge along the east coast of Queensland and the moist onshore winds. The trough system should move east across the state on Friday, generating a high chance of showers and possible thunderstorms with its passage, particularly over the southern interior and southeast of the state. A slight to medium chance of showers over eastern districts elsewhere. Fine and mostly sunny in the west as a drier air mass moves in behind the troughs wake.
Saturday 11 July
The trough system will rapidly move east during the day with a slight to medium chance of showers clearing eastern districts during the morning. A new large high will build over southwestern Australia and extend a dry and cooler across the state. Meanwhile a secondary surface trough will move into southwestern Queensland during the day, bringing an even colder air mass into the state.
Sunday until Tuesday
The large high will remain almost stationary over southwestern Australia as a deep low develops off the southeastern Australian coast. The combination of these two systems will result in a cold and dry air mass spreading through most of the state. Areas of morning frost are likely across much of southern Queensland with any chance of showers likely to be confined to the far northern tropics or in the far southern interior.
The next routine forecast will be issued at 4:30 am EST Wednesday.
