Australia -- Queensland Weather Update

MELBOURNE - Nov 23/11 - SNS -- The current forecast for the state of Queensland was released by Australia's Bureau of Meteorology.

Warning Summary at issue time
For the latest warning information please check the Bureau's
web site www.bom.gov.au/qld
Weather Situation
A weak ridge will maintain a moist onshore wind flow over much of the east
coast during the outlook period. This moist air feeds into a slow moving surface
trough that extends from the northwest of the state into the Maranoa. A coastal
trough and an associated S'ly wind change will move north into far southern
Queensland waters on Thursday. An upper level low will develop to the southwest
of the state this evening and remain slow moving into Thursday, maintaining a
thundery rain band over much of the interior.
Forecast for the rest of Wednesday
A band of rain and thunderstorms stretches from the northwest of the state,
through the central interior and into the Maranoa and Warrego district and
southeast interior. Moderate to locally heavy falls are expected within this
cloud band. Showers and thunderstorms over the northern tropics and through the
southern tropical interior. Showers and isolated thunderstorm over the Southeast
Coast district, increasing to thundery rain areas south of Brisbane tonight.
More isolated shower and thunderstorm activity elsewhere over central and
southeast districts with thunderstorms occurring mainly inland. Mostly fine in
the southwest with only isolated light showers. Light to moderate NE to NW winds
over eastern districts, fresh at times near the coast.  Moderate to fresh S to
SE winds in the west.
Forecast for Thursday
A cloud band with rain and thunderstorms will continue to extend from the
central interior through the Maranoa and Warrego and Darling Downs and Granite
Belt districts. Widespread moderate falls with some localised heavy falls are
expected within the band through areas east of about Longreach to Charleville.
Patchy rain and thunderstorms through the northwest of the state. Mostly fine
elsewhere in the west with only isolated showers over the southern Channel
Country. Rain areas and isolated thunderstorms over the Southeast Coast district
and southern Wide Bay and Burnett with some moderate falls, possibly locally
heavy near the S'ly wind change.  Showers and thunderstorms through the northern
tropics and southern tropical interior with some moderate falls possible with
storms. More isolated shower and thunderstorm activity elsewhere over the east
coast. Cool maximum temperatures over much of the interior and southeast.
Moderate to fresh NW to NE winds over the far southern coast ahead of a S'ly
wind change extending from the south. Light to moderate SE to NE winds elsewhere
over eastern districts. Moderate SW to SE winds in the far west, tending moist
NW to NE elsewhere over the interior.
Forecast for Friday
The upper level low will begin to move towards southeastern Australia. Fine
conditions are expected over the southwest. The thundery rain band will persist
elsewhere over the southern and central interior with some moderate to locally
heavy falls likely. Showers and thunderstorms will continue through the
northwest with some moderate falls likely with thunderstorms. Scattered showers
and possible isolated thunderstorms are expected in a continued moist and
unstable airflow on the east tropical coast. The coastal trough will weaken over
the southern Queensland coast and a ridge should then suppress activity with
only showers expected. Maximum temperatures will again be below average under
the thundery rain band and in the southwest of the state.
Forecast for Saturday
The upper level system will move southeast over southeastern Australia. The
thundery rain band should therefore weaken and contract east over southeastern
districts and the central interior of Queensland, most likely reaching the
southeast coast by the afternoon. Some moderate falls remain likely,
particularly with thunderstorms. Isolated showers are expected along the Wide
Bay and central coasts ahead of the rain band. Instability should decrease over
the northeast tropical coast, with more isolated shower and possible
thunderstorm activity expected. Showers and thunderstorms will continue
elsewhere over northern Queensland with some moderate falls likely with storms.
Fine conditions are expected south and west of Longreach.
Forecast for Sunday
A deep ridge should develop on the east tropical coast south of Coen with
only isolated showers expected. Unstable conditions will persist elsewhere over
northern Queensland with showers and isolated thunderstorms expected. The upper
level low will most likely contract east off the Victorian coast into the Tasman
Sea. The patchy, thundery rain band over southeastern and central districts will
therefore weaken further into shower and isolated thunderstorm activity and
contract northeast to be north of about Richmond to Fraser Island. Fine
conditions are expected elsewhere.
Outlook for Monday, Tuesday and Wednesday
The upper low will decay on Monday, though a weak surface trough should
maintain some shower and thunderstorm activity through the far northwest and the
central interior. This shower and thunderstorm activity should then become a
little more extensive through the central and southern interior on Tuesday and
Wednesday ahead of a new surface trough moving into western districts. Isolated
showers on the east tropical and central coasts should increase to scattered
from Tuesday with possible isolated thunderstorms due to a trough moving west
over the Coral Sea. Showers and possible isolated thunderstorms should occur
through southeast districts, mostly inland.
The next routine forecast will be issued at 4:45 am EST
Thursday.
