Forecast issued at 4:30 pm EST on Saturday 25 April 2015.
A strong high lies in the Southern Ocean off southwestern Australia and will move slowly eastwards over the next few days, extending a strengthening ridge into Queensland with generally fine, dry and cool conditions continuing.
Forecast for the rest of Saturday
A slight chance of showers over Cape York Peninsula and Torres Strait. Fine and mostly clear elsewhere. Moderate to fresh and gusty south to southwesterly winds in the far west, with light to moderate west to southwesterly winds elsewhere.
Sunday 26 April
Fine and sunny for the majority of the state, fine and mostly sunny over the far northern Peninsula. Moderate to fresh and gusty southwesterly winds extending over southeast districts, with light to moderate south to southwesterly winds elsewhere. Temperatures will drop to be well below average over the interior of the state.
Fire Danger - Very high in the Central Highlands and Coalfields, the Herbert and Lower Burdekin, the Central Coast and Whitsundays and in the Capricornia districts.
Monday 27 April
A high will push east into far southern parts of the Great Australian Bight, maintaining a firm ridge and a dry, cool airmass over much of the state. Fine and sunny conditions for most of the state, with just a slight chance of a late shower about the southeastern coastal strip. Temperatures remaining well below average, particularly over the interior. Some early morning frost is possible about the Maranoa, Granite Belt and and eastern Darling Downs.
Tuesday 28 April
The high will shift further eastwards through the Great Australian Bight. Another cold morning is expected over much of the state, with some early frosts possible over the Maranoa, eastern Darling Downs and Granite Belt. Maximum temperatures will also remain well below average in the west. Winds will gradually tend more moist onshore about the southern coast and nearby inland, with the slight to medium chance of showers developing. A slight to medium chance of showers will also persist about northern Cape York Peninsula and Torres Strait. Fine and sunny conditions are expected elsewhere.
Wednesday 29 April
The high shifts further eastwards through southern Victoria. A cold morning in the interior of the state, with the slight chance of frost over the northern Maranoa and Warrego district. Maximum temperatures remain well below average in the far west, but warm a little elsewhere over the interior. East to southeasterly winds are expected to push moisture into the east of the state, with a slight to moderate chance of showers over the east coast and southeast Queensland, enhanced by an intensifying upper trough lying over the southwest. Fine and sunny conditions are expected elsewhere.
Thursday until Saturday
The large high should continue moving slowly eastwards through the Tasman Sea during the forecast period, maintaining a firm ridge over Queensland. The upper trough will continue shifting eastwards, entering southeastern Queensland on Friday. A surface trough will deepen over the interior and shift east, also entering the southeast of the state on Friday. The moist wind flow to the east of the surface trough will combine with instability provided by the upper trough to generate showers and possible storms near and to its east, particularly over southeast districts, contracting eastwards during the outlook period. Moisture will also increase about the northern and eastern tropics with a slight to medium chance of showers developing. Daytime temperatures will remain cool through western and southern districts, particularly under the cloud cover in the southeast.
The next routine forecast will be issued at 4:30 am EST Sunday.
