Forecast issued at 4:30 am EST on Saturday 23 May 2015.
A strong, slow moving high pressure system over southeastern Australia will extend a firm ridge into Queensland during the forecast period. The high will start to slowly weaken early next week.
Forecast for the rest of Saturday
The slight chance of a shower near the southern coast and southern border ranges, increasing to a medium to high chance over the exposed coast and islands. Just the slight chance of a shower developing over the northern Peninsula and near the central coast. Fine and sunny through the interior. Possible early light frost near the Carnarvon Ranges and about the Granite Belt. Moderate to fresh and gusty south to southeasterly winds, strong near the southern and far north tropical coasts.
Sunday 24 May
The slow moving high over southeastern Australia will maintain a firm ridge and fresh to strong southeasterly winds about the east Queensland coast. A medium chance of showers is expected near the east coast, with a slight chance extending to the nearby inland. Fine and sunny conditions will persist over the interior. Some early light frost may occur on the Granite Belt and near the Carnarvon Ranges.
Monday 25 May
The high will remain slow moving near the New South Wales coast, maintaining a firm ridge and fresh to strong southeasterly winds about much of the east Queensland coast. A medium chance of showers is expected near the east coast, with a slight chance extending to the nearby inland. Fine and sunny conditions will persist over the interior apart from the far southwest where some high cloud should develop. Some early light frost is possible on the Granite Belt.
Tuesday 26 May
The high and ridge weakens slightly though a moist onshore wind flow will persist, with a slight to medium chance of showers expected over eastern districts. Fine and mostly sunny conditions are expected elsewhere.
Wednesday until Friday
The high will move slowly southeast over the Tasman Sea during the outlook period, gradually relaxing the ridge about the east Queensland coast. Some showers will occur over eastern districts in the onshore wind flow, more likely near the east tropical coast. Some high cloud and patchy light rain may develop through the far southwest of the state due to the passage of a series of weak upper level troughs. A surface trough will most likely enter the southwest of the state on Friday, increasing the chance of some patchy rain or shower activity. Fine and sunny conditions should persist over the remaining interior.
The next routine forecast will be issued at 4:30 pm EST Saturday.
