Forecast issued at 4:30 am EST on Tuesday 29 July 2014.
A ridge and dry airmass will dominate weather over much of the state during the next few days, with daytime temperatures remaining above average through southern, central and western districts. A trough will shift east over southern Queensland on Friday, with warm northerly winds to its east tending cool southwesterly in its wake. Little or no rainfall is expected with the trough passage. A strong high pressure system will enter the Great Australian Bight on Friday, extending a firm ridge into western Queensland in the wake of the trough.
Forecast for the rest of Tuesday
Isolated light showers about the north tropical coast. Fine and sunny elsewhere. A cold morning through the southern, central and southeast inland with some early frosts. Daytime temperatures generally above average away from the tropics. Moderate to fresh east to southeasterly winds about the tropics and central coast. Moderate westerly winds developing over southern districts and tending northerly near the southern coast in the afternoon. Mostly light winds elsewhere.
Wednesday 30 July
A weak ridge will persist through southern Queensland and about the north tropical coast. Much of the state will remain fine with only isolated showers expected about the east tropical coast and also possibly developing near the central coast as low level moisture increases. Early frosts will continue through the southern and southeastern inland, while daytime temperatures will remain above average away from the tropics.
Thursday 31 July
A trough will most likely enter southwestern Queensland late in the day, though no rainfall is expected to accompany it due a dry airmass persisting. Daytime temperatures will warm further through western and southern districts in the northwesterly winds ahead of the trough, though early frosts will continue through the southern and southeast inland. A moist onshore wind flow should result in isolated shower activity about the east coast and nearby inland near and north of Yeppoon.
Friday 1 August
The trough is expected to shift east over southern Queensland, most likely contracting off the southern coast during the evening. Little or no rainfall is expected with the passage of the trough. Warm northwesterly winds ahead of the trough will tend cooler southwesterly in its wake. A new, strong high will enter the Great Australian Bight, extending a firm ridge through western Queensland in the wake of the trough. Some light shower activity may occur near the north tropical coast, mostly during the morning. Widespread morning fogs are likely through eastern districts.
Saturday until Monday
The strong high is expected to move slowly east over southern Australia, maintaining a firm ridge over Queensland. Cool southerly winds will extend further through western and southeastern Queensland on Saturday, with early frosts returning to inland parts. Fresh to strong southeasterly winds and isolated showers will develop about the east coast, possibly extending to nearby inland parts on Monday. The ridge should maintain fine and mostly sunny conditions through the interior.
The next routine forecast will be issued at 4:30 pm EST Tuesday.
