Forecast issued at 4:30 pm EST on Wednesday 2 December 2015.
An upper trough and an associated patchy cloud band over southeast and central Queensland will move east this evening and contract off the southern and central coast early Thursday. A surface trough extends from the northwest of the state into the western Darling Downs, with unstable conditions extending over areas near and to its east. This trough should retreat slowly west over the interior of the state from Thursday. A coastal trough will enter far southern Queensland waters late tonight and shift north to the central coast during Thursday and Friday. A high will enter the Tasman Sea on Friday, extending a firm ridge about the east Queensland coast in the wake of the trough.
Forecast for the rest of Wednesday
A cloud band with patchy, thundery rain over central and southeast districts will move east, clearing the southern coast in the evening. A medium to high chance of showers and storms is expected over the southeast - some storms may be severe. A slight to medium chance of showers and storms from the northwest into the central west. Fine and clear conditions through the southern interior. A medium to high chance of showers over the northeast tropics, with possible isolated storms. Moderate southeast to northeast winds in northern and eastern districts. Moderate to fresh and gusty south to southwesterly winds extending through western areas and the southern interior.
Thursday 3 December
A medium chance of showers in the far southeast following the passage of the coastal trough, with cooler and windy conditions expected south of the trough. Fine and sunny conditions will persist through the southwest of the state. A slight to medium chance of showers and storms over most remaining areas, increasing to a high chance over the Wide Bay and Capricornia districts near the coastal trough. A medium to high chance of showers and storms are expected about Cape York Peninsula. Moderate to fresh and gusty south to southeasterly winds in southeast parts behind the coastal trough. Moderate to fresh and gusty south to southwesterly winds extending through western areas and the southern interior. Moderate southeast to northeast winds elsewhere.
Fire Danger - Very High in the North West district.
Friday 4 December
The high in the Tasman Sea will extend a ridge along the Queensland east coast with fresh to strong southeasterly winds leading to a slight to medium chance of showers about the east coast and adjacent inland, more likely on the central and southern tropical coasts with possible isolated storms due to the coastal trough moving north over the area. The inland surface trough should shift further west into western Queensland, with the slight chance of showers and storms over the interior near and to its east, increasing to a medium chance in the northwest.
Saturday 5 December
The high in the Tasman Sea will start to weaken though maintain a ridge over eastern Queensland with onshore winds producing a slight chance of showers about much of the east coast. The surface trough in the far west of the state will result in the slight chance of showers and storms, more likely about the far northwest of the state where moisture levels are higher. The slight chance of a shower will extend into the tropical interior, with possible isolated storms over the northern Peninsula. Remaining areas should be fine and mostly sunny.
Sunday 6 December
The high will weaken further though a new high will enter the Tasman Sea on Monday, maintaining a weak ridge along the east Queensland coast. A more stable upper pattern will develop over much of the state through the outlook period until a new upper trough enters western Queensland on Tuesday. Storms are expected to contract to far western parts of the state before extending further east over the interior on Tuesday as the new surface and upper trough enter western Queensland. Mostly fine conditions are expected in the tropics and through the east. Hot conditions will again develop through western Queensland during the outlook period as winds tend northerly ahead of the new surface trough.
The next routine forecast will be issued at 4:30 am EST Thursday.
