Australia -- Queensland Weather Update

MELBOURNE - Oct 21/13 - SNS -- The current forecast for the state of Queensland was released by Australia's Bureau of Meteorology.

Weather Situation
A high (1026 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 will enter western Queensland on Tuesday and should then shift east over the interior of the state during Wednesday. A mid level trough will move from the Coral Sea onto the northeast tropical coast late Monday or early Tuesday and should then shift west through the northern tropics during Tuesday and Wednesday, increasing the instability over this region.
Forecast for the rest of MondayCloudy periods with isolated showers about the east tropical and central coasts, more frequent about the Cassowary Coast. Possible isolated showers and gusty thunderstorms over areas south and west of about Quilpie and through the far western Gulf Country, though with little or no rainfall expected. Fine and mostly clear elsewhere. Moderate to fresh and gusty northwest to northeasterly winds through the west and southern interior. Fresh and gusty southeasterly winds about the east coast north of about Yeppoon. Light to moderate east to northeasterly winds elsewhere.Tuesday 22 OctoberMostly cloudy with isolated showers and thunderstorms are expected in the northern tropics and near the Gulf of Carpentaria, with showers tending more scattered about the North Tropical Coast. Isolated showers along the southern tropical and central coasts will contract northwards during the day. Isolated showers and gusty thunderstorms are possible in the southwest, though little or no rainfall is expected. Fine and mostly sunny conditions are expected elsewhere. Hot conditions and elevated fire dangers will persist through the southern and southeastern interior in the fresh and gusty northerly wind flow ahead of the trough, particularly through the southwest. Winds are expected to shift fresh and gusty south to southwesterly in the wake of the trough. Fresh and gusty southeasterly winds about the east coast north of the Capricornia coast. Light to moderate east to northeasterly winds elsewhere.Fire Danger -  Severe in the Maranoa and Warrego and Channel Country. High to Very High elsewhere.Wednesday 23 OctoberThe trough will move eastwards over the interior of the state and will most likely extend from the Gulf Country to the southwestern Darling Downs at night. Isolated showers and gusty thunderstorms are expected to develop near the trough in the southern and central interior, and Gulf Country, increasing to scattered in the southern interior during the afternoon and evening. The ridge will relax further along the east Queensland coast and the mid level trough will shift further west, resulting in a decrease in shower activity along the northeast tropical coast during the day. The mid level trough will most likely result in isolated showers over the Peninsula district, increasing to scattered showers and isolated thunderstorms in the afternoon and evening. Isolated light showers will possibly occur about the central, Capricornia, and Fraser coasts in an onshore wind flow. Fine and mostly sunny conditions are expected elsewhere. The hot conditions and enhanced fire dangers will spread through the Maranoa and Warrego into southeast districts in the moderate to fresh and gusty north to northeasterly wind flow ahead of the trough. A cooler, fresh and gusty south to southwesterly wind flow will develop in the wake of the trough.Thursday 24 OctoberThe trough will continue moving eastwards and will most likely contract off the southern Queensland coast late in the day. The trough is expected to generate scattered showers and gusty thunderstorms over southeast and southern central districts with its passage. Temperatures will also rise to be well above the October average through these parts in the fresh northerly wind flow ahead of the trough. Isolated showers and thunderstorms will possibly 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 Cooktown, with isolated thunderstorms again expected along the west Peninsula coast.Friday 25 October
The trough is expected to move north along the Capricornia coast and remain almost stationary in the interior with showers and thunderstorms primarily focused near the trough in the Capricornia, Wide Bay and southern central interior. Isolated showers and thunderstorms are also possible near the trough from the northern central interior up to the southern and eastern gulf coast. A cooler more stable south to southeasterly wind change will extend through areas in wake of the trough with fine and sunny conditions apart from isolated showers in the southeast and along the Peninsual coast.
Saturday until MondayThe unstable conditions and thunderstorm activity should contract offshore during the weekend with the passage of an upper level trough. The high will move slowly east towards southeastern Australia, extending a ridge along the east Queensland coast with isolated showers along much of the coast on Saturday before decreasing as the ridge weakens. The thunderstorm activity about the west Peninsula coast shifts to the Gulf Country coast on Saturday and Sunday before most likely clearing on Monday. A new trough system will possibly enter the southwest on Monday with increasing instability leading to a greater chance of showers and thunderstorms in the southern interior.The next routine forecast will be issued at 4:30 am EST Tuesday.Product IDQ10700
