Australia -- Queensland Weather Update

MELBOURNE - Aug 20/17 - SNS -- The current forecast for the state of Queensland was released by Australia's Bureau of Meteorology.

Weather Situation
A large high pressure over southeastern Australia extends a firm ridge into Queensland. The high will weaken while shifting northeast, most likely moving into the northern Tasman Sea by late this evening. A dry air mass will result in extensive early frosts over the central and southern inland this morning. A long period, south to southeasterly swell extends into southern Queensland waters this morning, expected to abate during the afternoon. An upper trough and an associated cloud band will shift east over the south of the state, generating some patchy light rain and possible isolated storms with its passage, more likely nearer to the New South Wales border, before clearing the southern coast early Tuesday. A ridge will then extend into western Queensland from Tuesday whilst a slow moving, weak surface trough will extend from the central interior into the southeast inland. A new high pressure system will most likely develop over southeastern Australia late in the week, with winds then gradually tending more onshore about the east Queensland coast.
Forecast for the rest of MondayThe slight chance of showers about the east coast and nearby inland, more likely over the central coast and near Fraser Island. A cloud band with some patchy light rain and possible isolated storms shifting east over southern districts, more likely nearer to the New South Wales border and possibly reaching the Gold Coast at night. Fine and sunny elsewhere. Daytime temperatures increasing in the northwest. Another cold morning for much of the state away from the far northern tropics, with areas of morning frost over inland parts, particularly central and southern districts. Moderate to fresh north to northeasterly winds over the interior. Light to moderate southeast to northeasterly winds elsewhere, fresh about the far northern tropics. South to southeasterly swell over southern waters abating from the afternoon.Fire Danger -  Very High over the Maranoa and Warrego district.Tuesday 22 AugustThe upper trough and associated cloud band with possible patchy light rain is expected to move through the southeast and into the Coral Sea early in the morning. The slight chance of showers will occur again in the far southeast through the afternoon however as a surface trough becomes slow moving from the central interior of the state to the southeastern interior. Very dry conditions will extend into western Queensland to the west of the surface trough. The slight chance of light showers will persist over the northeast tropical coast where the wind flow remains more onshore. Maximum temperatures will increase further over most of the state, particularly through central and southern districts. Possible early frosts will be confined to the Granite Belt.Wednesday 23 AugustA weak coastal trough will move through far southern Queensland waters in the morning. An inland surface trough will remain slow moving from the central interior to the southeastern inland of the state, with dry conditions persisting to its west. A slight chance of a shower about the central east, to the east of this feature. The slight chance of a shower will persist about the northeastern tropics in an onshore wind flow, more likely over the northeastern Peninsula. Morning frosts will likely occur over the southeastern inland and through the Maranoa to the Carnarvon Ranges as drier conditions extend into the region again. Maximum temperatures will remain above the August average through much of the state, particularly through central parts, the Maranoa and Warrego and southeastern districts.Thursday 24 AugustThe inland surface trough will remain slow moving from the central interior into the southeastern inland whilst a coastal trough will likely extend into far southern Queensland waters. An upper level trough will extend north into southern Queensland, combining with the relatively moist air mass ahead of the surface trough to result in the slight chance of showers through central districts into the far southeast, increasing to a a slight to medium chance through the Wide Bay and about the exposed southern coast. The slight chance of a light shower will persist about the northeast tropical coast, with fine and dry conditions elsewhere. Morning frosts will remain possible over the southeastern interior, particularly the Granite Belt. Maximum temperatures will remain above average over much of the state.Friday until SundayA slow moving high pressure centre will likely develop over southeastern Australia on Friday whilst another, stronger high centre will shift east into the Great Australian Bight through the weekend. This will result in winds tending more onshore about the east Queensland coast. The surface trough over the central interior of the state will likely move slowly west through the weekend, possibly extending from the northern interior through the Central West and Warrego by Sunday. A series of upper level troughs will move north into southern Queensland through the outlook period, combining with the onshore wind flow to result in some showers developing over southeast and central parts of the state, possibly extending further into the central and southern interior through the weekend as the surface trough shifts west. The upper trough may amplify further on Sunday, resulting in an increased chance of storms near the surface trough over the interior, though there is some uncertainty associated with this development. The slight to medium chance of showers will develop over the remaining east coast and nearby inland, becoming more likely through the weekend as the onshore wind flow increases. Maximum temperatures will remain generally near or a bit above the August average over most of the state. Morning frosts will remain possible over the southeastern interior.The next routine forecast will be issued at 4:30 pm EST Monday.Product IDQ10700
