Forecast issued at 4:30 pm EST on Sunday 24 September 2017.

Weather Situation

A high over the Tasman Sea extends a ridge onto the tropical east coast of Queensland. A vigorous surface trough lies over the southwest of the state and will move slowly eastwards over the southern interior during today and Monday. Hot, dry and gusty northwesterly winds will extend over much of southern Queensland ahead of this feature, resulting in very high to severe fire dangers on Monday. The trough will then weaken while shifting a little further west on Tuesday. A series of weak upper troughs will maintain some instability over the south of the state, though any resulting storms are not expected to have much if any rain associated with them. Temperatures will remain well above the September average over much of the southern half of the state and the northwest in the week ahead. A coastal trough may provide a slight drop in temperature to the southern coast on Tuesday and Wednesday. A new trough will most likely move east into the interior of the state on Thursday, again resulting in enhanced fire dangers. The southerly flow in the wake of the trough will likely provide a large drop in temperature to areas in the far southwest of the state from Thursday, while hot to very hot conditions will persist over remaining southern districts.

Forecast for the rest of Sunday

Mostly fine in the tropics with just the slight chance of a light shower over Torres Strait. The slight chance of showers and storms over the southern interior southeast of Quilpie into the southeastern inland, more likely nearer to the New South Wales border though with little to no rainfall expected. Moderate southeast to northeasterly winds in the tropics. Light winds in the far southwest. Fresh to strong and gusty north to northwesterly winds elsewhere, locally damaging wind gusts over the remaining southern interior south and west of Mitchell.

Monday 25 September

The slight chance of isolated showers and storms over southern districts southeast of about Quilpie to Ipswich, though with little to no rainfall expected. Some cloud will develop over the northern Channel Country and northwest of the state in the afternoon though with no rain expected. Fine and mostly sunny elsewhere apart from the slight chance of a light shower through Torres Strait. Hot, gusty northwesterly winds ahead of the trough will continue to result in enhanced fire dangers over parts of the southern interior and southeast. Light to moderate southeasterly winds in the far southwest. Moderate to fresh southeast to northeasterly winds over the northern tropics. Fresh and gusty north to northwesterly winds elsewhere.

Fire Danger - Severe over the Maranoa and Warrego and Darling Downs and Granite Belt districts. Very high over remaining western and southern districts and through the central and northern interior.

Tuesday 26 September

A new high pressure system will move east into southeastern Australia. The inland surface trough over the south of Queensland will likely shift to the west in response to the building ridge about the east coast. A coastal trough will possibly move north from New South Wales along the far southern Queensland coast. The slight chance of isolated afternoon showers and storms will persist in the far south of the state, though with little to no rainfall expected. Hot conditions will persist over the interior and southeastern interior of the state, while the coastal trough will likely result in a slight drop in temperature near the southern coast.

Wednesday 27 September

The surface trough is likely to decay over inland Queensland, while a new cold front develops through central Australia and moves east towards the state. Northwesterly winds will strengthen in the far southwest of the state ahead of this feature and very hot conditions will extend through the southern and central interior. The coastal trough near the southern coast will continue to moderate temperatures a little there. Cloud will likely increase in the far southwest of the state late in the day ahead of the cold front though with no rainfall expected. Fine conditions will persist elsewhere apart from the slight chance of a light shower over the very far northern Peninsula.

Thursday 28 September

The cold front will move further east over southeastern Australia, with an associated vigorous surface trough moving east over the interior of Queensland. Temperatures will drop significantly in the far southwest of the state in the wake of the trough. A strong and gusty northwesterly wind flow will extend over the remaining southern interior and southeastern corner of the state with very hot conditions and enhanced fire dangers expected. Some high cloud will extend into the far southwest and along the southern border ahead of an upper trough though with little to no rainfall expected.

Friday until Sunday

The trough will likely weaken while remaining slow moving on Friday. Yet another trough will possibly move east over southeastern Queensland during Saturday. A new high pressure system to the southwest of Western Australia will then extend a firm ridge into southern Queensland in the wake of the trough on Sunday. Temperatures will likely remain above the September average over much of western, central and southern Queensland though should start to moderate from Sunday as a ridge builds over the east Queensland coast. Some high cloud will likely extend over the far southern interior during Friday and Saturday ahead of an upper trough with possible isolated showers and storms though with little rainfall expected. There is some uncertainty associated with the movement of the upper trough. At this stage the most likely scenario is for it to move further eastwards over the interior of Queensland on Sunday, with the slight chance of isolated showers or storms possibly extending east into the southeast of the state. The tropics will remain fine apart from the chance of isolated light showers near the coast in an onshore wind flow..

The next routine forecast will be issued at 4:30 am EST Monday.
