Forecast issued at 4:30 pm EST on Tuesday 2 September 2014.
A vigorous surface trough lies through far eastern districts and is expected to move off the southern east coast during the evening and then off the remaining east coast overnight. Cool south to southwesterly winds are expected across the whole state of Wednesday in the wake of the trough. A ridge of high pressure will then build across much of the state from Thursday through until Saturday.
Forecast for the rest of Tuesday
Fine and mostly clear across. Moderate to fresh northwesterly winds about coast parts of the Capricornia, Wide Bay and Burnett and Southeast Coast districts, becoming fresh and gusty west to southwesterly during the early evening. Fresh and gusty south to southwesterly winds elsewhere.
Wednesday 3 September
Fine and sunny conditions for much of Queensland. Early frosts are likely through the southern and southeastern interior. A large south to southeasterly swell is expected to develop through Gold Coast waters from the late afternoon or evening. Fresh and gusty southwesterly winds about the southeast of the state. Moderate to fresh south to southwest winds elsewhere. Maximum temperatures will be several degrees below the September average in the dry southerly flow.
Thursday 4 September
A large high will enter the Great Australian Bight, extending a ridge and dry airmass into Queensland with fine and mostly sunny conditions expected across the state. The clear skies and lighter winds should lead to early frosts through the southern, central and southeast interior. The deep low in the Tasman Sea will continue to extend a large south to southeasterly swell into Gold Coast waters.
Friday 5 September
The high should move slowly east across southeast Australia whilst the low in the Tasman Sea will move eastwards towards New Zealand. Much of the state should be fine and sunny, although an upper trough may produce isolated showers about the southeast interior. Early frosts will continue over the southern, central and southeast inland. Swells should tend to ease over far southern waters as the low in the Tasman Sea moves to the east.
Saturday 6 September
The high should remain slow moving over southeast Australia, extending a ridge along the east coast of Queensland. An upper level trough will possibly enter southeast Queensland, leading to the chance of isolated showers about the southeast interior, mainly about the Granite Belt and Border Ranges. The remainder of the state should be fine and mostly sunny. Early frosts should continue about the Granite Belt.
Sunday until Tuesday
The high should continue to move slowly eastwards into the Tasman Sea through the outlook period, extending a firm ridge along the east Queensland coast. There remains some uncertainty about the development of an upper trough over Queensland through the outlook period but the most likely scenario is for isolated showers and possible storms over central and southeastern districts on Sunday to contract eastwards on Monday and Tuesday.
The next routine forecast will be issued at 4:30 am EST Wednesday.
