Australia -- Queensland Weather Update

MELBOURNE - Oct 20/13 - 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 from today 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. Isolated showers near the southern and Capricornia coasts, mainly during the morning and early afternoon. 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 sunny elsewhere. A hot day in the west and through the southern interior with moderate to fresh and gusty northwest to northeasterly winds. Fresh and gusty southeasterly winds about the east coast north of about Yeppoon. Light to moderate east to northeasterly winds elsewhere.Fire Danger -  Very High over much of the interior, increasing to Severe in the Channel Country district.Tuesday 22 OctoberA trough will enter and move over the southwest of the state, resulting in increasing cloud through the southwest with isolated showers and possible gusty thunderstorms, though little or no rainfall is expected. 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. The ridge along the east Queensland coast will weaken further, while a mid level trough will enhance shower activity about the northeast tropical coast. Isolated shower activity is expected about the remaining east coast north of about Yeppoon. Isolated thunderstorms about the western Gulf Country and may also develop about western Cape York Peninsula late at night. Fine and mostly sunny conditions are expected 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. Cloud will increase further through the southern interior with isolated showers and gusty thunderstorms expected, increasing to scattered near the trough 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 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 until SundayShowers and thunderstorms are expected to focus through the Capricornia, Wide Bay, northern Darling Downs and southern central interior on Friday as a cooler, more stable south to southeasterly wind change extends through areas to the south. The unstable conditions and thunderstorm activity should then 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 otherwise. A weak trough will most likely persist through the northwest and central interior with patchy cloud developing during the afternoon though little or no rainfall is expected. The thunderstorm activity about the west Peninsula coast shifts to the Gulf Country coast on Saturday before most likely clearing on Sunday. Dry and sunny conditions should persist in the southwest.The next routine forecast will be issued at 4:30 pm EST Monday.Product IDQ10700
