Australia -- Queensland Weather Update

MELBOURNE - Oct 22/13 - SNS -- The current forecast for the state of Queensland was released by Australia's Bureau of Meteorology.

Weather Situation
A high (1024 hPa) over the eastern Tasman Sea extends a firm ridge along the east Queensland coast. The ridge will gradually relax over the next few days as the high shifts further east and weakens. A surface trough over southwestern Queensland will shift east over the interior of the state during today before contracting off the southern Queensland coast late Thursday. This trough will then extend northwards along the east coast to about St Lawrence during Friday. A mid level trough will move west through the northern tropics during today.
Forecast for the rest of WednesdayIsolated showers and thunderstorms developing near the trough in western parts of the state, increasing to scattered in the southern interior during the afternoon and evening. Isolated showers about the east coast north of Fraser Island decreasing during the day. Isolated showers and thunderstorms also developing late in the day about the Gulf coast. Moderate to fresh and gusty north to northeasterly wind winds ahead of the trough will give way to cooler, fresh and gusty south to southwesterly winds in the wake of the trough. Moderate northeast to southeasterly winds elsewhere in the state.Fire Danger -  High to Very High throughout much of the state.Thursday 24 OctoberThe eastward moving trough will generate scattered showers and isolated gusty thunderstorms over southeast and southern central districts. Some thunderstorms could be severe over parts of the southeast. Isolated showers and thunderstorms will develop on the inland section of the trough through the northwest and central interior. A large high will move east into the Great Australian Bight, extending a firm ridge into southwestern Queensland in the wake of the trough with dry, sunny and cooler conditions expected. A moist onshore wind flow will result in isolated showers over the tropics north of about Lockhart River, with isolated thunderstorms again expected along the west Peninsula coast.Friday 25 OctoberThe trough and an associated cooler south to southeasterly wind change is expected to move north through southern Queensland waters into Capricornia waters. The inland portion of the trough is expected to remain slow moving through the central interior. This will result in isolated showers increasing to scattered through the central interior, Capricornia and northern Wide Bay with isolated gusty thunderstorms possible. Isolated showers and thunderstorms are also possible near the trough through the central west into the tropical interior and southern Gulf of Carpentaria coast. Isolated showers will occur over the southeast near and east of the Great Dividing Range in a moist onshore wind flow and should be more scattered near the coast during the morning due to the trough passage. Isolated light showers will also possibly develop over the northeast tropical coast.Saturday 26 OctoberMost of the unstable conditions and thunderstorm activity should contract offshore with the passage of an upper level trough, however isolated showers are expected to persist over the Capricornia, Central Coast and adjacent inland. Isolated thunderstorms are possible over the central highlands. The coastal trough will weaken near the central coast leading to scattered showers about the coast during the morning. The high will move slowly east towards southeastern Australia, extending a ridge along the east Queensland coast with isolated showers along much of the remainder of the coast. Thunderstorm activity remains likely near the southern Gulf of Carpentaria coast.Sunday until TuesdayAnother upper trough is expected to bring scattered showers to the southeast during Sunday, but will ease into Monday. The high will move into the Tasman Sea and continue to extend a ridge along the eastern Queensland coast during Monday. Isolated showers are possible along the east coast before contracting northwards later on Monday as the ridge weakens and a new trough system enters western Queensland. The atmosphere will destabilise ahead of the trough in western and southern Queensland on Tuesday, with increasing potential of showers and thunderstorms across the southwest and south of the state.The next routine forecast will be issued at 4:30 pm EST Wednesday.Product IDQ10700
