Queensland Forecast

No warnings for Queensland

Forecast issued at 4:30 am EST on Tuesday 22 August 2017.

Weather Situation

An upper trough will move east over southeastern Queensland and into the Coral Sea early this morning. A surface trough will shift east over the interior of the state today to extend from the northern interior through the central interior and into the southeastern inland by this evening. The trough will remain slow moving on Wednesday before shifting east through Thursday, possibly reaching the far southeast coast late Thursday night and then shifting north through southern waters during Friday. A new upper trough will move north towards southern Queensland on Thursday, increasing instability over the southeast of the state. This upper trough should then shift east into the Coral Sea during Friday. A high pressure system will move east into southeastern Australia on Friday, gradually extending a firm ridge onto the east Queensland coast. Winds will then tend more moist onshore about much of the east coast through the weekend.

Forecast for the rest of Tuesday

Patchy high cloud and possible isolated showers or storms clearing the southeast early this morning with an upper trough. The slight chance of light showers developing through the southeast this afternoon. Sunny with very dry conditions through western Queensland. The slight chance of light showers over the far northeast tropical coast. Maximum temperatures will increase further over most of the state, particularly through central and southern districts. Possible early frosts about the Granite Belt. Mostly moderate southeast to northeast winds for much of the east coast, tending north to northeasterly south of Fraser Island. Moderate west to southwest winds elsewhere.

Fire Danger - Very High about the Peninsula district.

Wednesday 23 August

A weak coastal trough will move through far southern Queensland waters in the morning. An inland surface trough will remain slow moving from the central interior to the southeastern inland of the state, with dry conditions persisting to its west. The slight chance of isolated light afternoon showers will occur through central and southeastern districts east of this feature, mostly over inland parts. The slight chance of light showers will persist about the northeast tropical coast. Morning frosts will likely occur over the southeastern inland and through the Maranoa to the Carnarvon Ranges as drier conditions extend into the region again. Maximum temperatures will remain above the August average through much of the state, particularly through central and southern districts.

Thursday 24 August

The inland surface trough will originally extend from the central interior into the southeastern interior though will likely move slowly east over the southeast of the state, possibly reaching Gold Coast waters late in the day. An upper level trough will extend north into southern Queensland, combining with the relatively moist air mass ahead of the surface trough to result in the slight to medium chance of showers and thunderstorms over the southeast, more likely over the Sunshine Coast and Wide Bay where the surface trough will likely remain to the west for much of the day. The slight chance of a light shower will persist about the northeast tropical coast north of Cairns, with fine and dry conditions elsewhere. Morning frosts will remain possible over the southeastern interior, particularly the Granite Belt. Maximum temperatures will remain above average over much of the state.

Friday 25 August

The surface trough is likely to move northwards through southern waters and into the Wide Bay district but it will remain slow-moving through the central inland and northern interior. The upper trough will move east through the southeast of the state and into the Coral Sea. Conditions will therefore stabilise through the day, though there may be some early storms over the Capricornia and Wide Bay districts before this occurs. The slight chance of showers will occur the central coast east of the surface trough, and may also develop through the far southeast though with little to no rain expected. The slight chance of light showers will persist over the far northeast tropical coast. A high will shift east into southeastern Australia, extending a firm ridge and a dry air mass into the interior of Queensland in the wake of the trough. The drier conditions will result in morning frosts becoming more widespread over parts of the southern and southeast interior.

Saturday until Monday

A high pressure centre will remain slow moving over southeastern Australia through the outlook period whilst a new, stronger high centre will likely develop over the southern Ocean or Great Australian Bight. The high centres will extend a firm ridge and moist onshore winds onto the east Queensland coast and nearby inland, with a slight to medium chance of showers developing, more likely over the northeast tropical coast. The surface trough over the northern interior and central inland will likely move slowly west to possibly extend from the northern interior to the Warrego by Monday, though there is some uncertainty associated with its movement. An upper level trough will extend into the south of the state on Saturday and should then amplify through the remainder of the outlook period, particularly on Monday. This will result in an increased chance of showers over the southeast of the state and through to the central and southern interior near the inland trough, with possible storms over the central and southern interior. Note however there is some uncertainty associated with this development. Maximum temperatures will remain generally near or a bit above the August average over most of the state. Morning frosts will remain possible over the southeastern interior.

The next routine forecast will be issued at 4:30 pm EST Tuesday.
