No warnings for Queensland
Forecast issued at 4:30 pm EST on Thursday 13 July 2017.
Weather Situation
A high pressure system over the Tasman Sea extends a firm ridge along the east coast of Queensland with showers and fresh southeasterly winds likely along parts of the coast. The high will move slowly eastwards and weaken during the next few days with showers and winds decreasing along the central and tropical east coast as the ridge slackens in response. An upper trough and associated surface trough are likely to move across Queensland on Friday and Saturday, most likely moving off the southeast coast on Sunday. A drier airmass is expected to move over the interior of the state in the wake of the surface trough.
Forecast for the rest of Thursday
A slight to medium chance of showers about the east coast and adjacent inland, increasing to a high chance about the north tropical coast. Fine and mostly clear elsewhere. Mostly moderate east to southeasterly winds, fresh and gusty at times about the northeast coast and Cape York Peninsula.
Friday 14 July
A slight to medium chance of showers about the east coast and adjacent inland, increasing to a high chance about the northeast tropical coast. Warm daytime conditions are likely over much of the state's interior, with a slight chance of showers over the southern interior during the afternoon and evening. Fine and mostly sunny conditions elsewhere. Morning frost patches are possible about parts of the southeastern interior. Mostly light to moderate northeast to southeasterly winds, fresh and gusty at times about the northeast coast and Cape York Peninsula.
Saturday 15 July
The surface trough should move east across the interior, most likely moving into eastern parts during the evening. This surface trough should combine with an associated upper trough to produce isolated showers and even some possible storms with the passage of these features, mostly in the south. Showers are expected to remain about the northeast coast in an onshore flow. Warm daytime conditions are likely ahead of the surface trough, with cooler and drier air extending into western parts in the wake of the trough.
Sunday 16 July
The surface trough will most likely push off the southern coast during the morning, with showers clearing the southern east coast at the same time. The high will push further east, with showers expected to remain about the northeast coast in the onshore flow. Another high will move into northern New South Wales in the wake of the trough, extending a cooler and drier air mass over southern and western areas, with morning frost likely about parts of the southern interior.
Monday 17 July
The high will shift east into the northern Tasman Sea and continue to extend a ridge along the east Queensland coast with showers possible in the onshore flow. A broad low pressure system approaching Tasmania will extend a surface trough into western Queensland, though little to no rainfall is expected with the trough's passage. Temperatures will tend to be warmer than the July average over much of the state, especially in the interior, though early morning frosts will be possible near the New South Wales in the southern interior.
Tuesday until Thursday
The low will move into the southern Tasman Sea and head towards New Zealand during the outlook period, with the surface trough sweeping east and north across the state. Showers will be possible ahead of the trough's passage on Tuesday with temperatures well above the July average. The possibility of showers will contract to the far northeast tropics on Wednesday and Thursday as the cooler and drier air mass moves through southern, central, southern tropical districts. Temperatures will revert to near normal in the wake of the trough under the influence of the cooler and drier air mass.
The next routine forecast will be issued at 4:30 am EST Friday.
