A high over the southern Coral Sea extends a ridge throughout most of Queensland. A surface trough lies over inland Queensland while a weak upper trough extends over southern parts of the state. These two systems will remain slow-moving during the coming days, before a new surface trough enters the southwest of the state during Sunday and moves east across the interior.
Forecast for the rest of Friday
A slight to medium chance of showers and possible storms in the southeast quarter of the state east of about Cunnamulla to Longreach, increasing to a medium to high chance about the southeast and southeastern interior, including the Carnarvon ranges. A slight chance of showers about the east coats north of about Townsville. Fine and mostly sunny elsewhere. Mostly moderate northwest to northeasterly winds, tending south to southwesterly over southwestern parts. Winds tending moderate east to southeasterly north of about Townsville.
Fire Danger - Very High about the Peninsula district and the Upper Flinders and Goldfields district.
Saturday 29 October
The upper trough will push into the Coral Sea, while the surface trough will remain slow moving over the interior. Showers and the chance of thunderstorms are possible through the southeast of the state. The high will move into the Tasman Sea, maintaining the strong ridge along the Queensland east coast. Slight chance of showers in the onshore wind flow for the northern tropical coasts. Fine and mostly sunny elsewhere.
Sunday 30 October
The high is expected to move southeast and weaken, with the ridge along the east Queensland coast easing as a result. A slight chance of showers in the onshore wind flow about the northern tropical coast. An upper trough is expected to develop over central Australia, extending patchy high cloud over western parts. A surface trough should move east across the interior. These two systems may cause some shower and possible storm activity about far southern parts of the state.
Monday 31 October
The surface trough is expected to move east across the interior and approach the southeast coast late in the day, while the upper trough also moves east across southern parts during the day. Shower and storm activity is possible near and east of the surface trough, most likely about southeast parts.
Tuesday until Thursday
The upper trough shifts through the south of the state on Tuesday and possibly into Wednesday, while another upper trough may develop over southwestern parts during Wednesday and move east. The surface trough should remain slow-moving about the eastern interior north of about the Sunshine Coast during Tuesday and Wednesday, before weakening on Thursday. Showers and possible storms are expected over eastern parts near and east of the surface trough.
