Australia -- Queensland Weather Update

MELBOURNE - Jun 26/13 - 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 high [1030 hPa] over the southern Tasman Sea extends a ridge over central
Australia and over the tropical east Queensland coast. A complex low pressure
system over the northern Tasman Sea is moving northeast and extends a surface
trough into southern Queensland. An upper level trough over far southwestern
Queensland is expected to move rapidly eastwards today.
Forecast for the rest of Thursday
Cloudy with isolated showers and morning drizzle over southeast districts and
the southern interior, increasing to scattered showers over parts of the
southeast during the day. Areas of middle and high cloud over western, central
and remaining southern districts but with little or no rain. Isolated light
showers over the far northeastern Peninsula District. Light to moderate SW to SE
winds, fresh at times along the northeast coast and far southern coast.
Forecast for Friday
The upper trough is expected to move offshore during the morning while a more
significant upper trough moves across Western and South Australia and begins to
intensify. A new high is expected to strengthen over the Great Australian Bight,
maintaining a moister S to SE flow into southern Queensland. Cloudy over most of
the southern half of Queensland, with scattered showers and some drizzle over
southeast districts and the southern interior. Scattered showers along the
southern coast and border ranges in a fresh S to SE airflow. A cool morning in
central districts and parts of the eastern tropics.
Forecast for Saturday
The high is expected to remain near South Australia and maintain a relatively
moist S to SE airflow over the southern half of Queensland, with cloudy
conditions and isolated showers. The upper trough is expected to move across New
South Wales and towards southwest Queensland, and will help to begin deepening a
surface trough off the east Queensland coast. This will assist in maintaining
scattered showers about the Southeast Coast and the Wide Bay. Fine over the
remainder of the state. Minimum temperatures remaining below average in central
districts and parts of the eastern tropics, with maximum temperatures trending
below average in the southeast.
Forecast for Sunday
The high is expected to remain over South Australia and maintain the
relatively moist S to SE airflow over the southern half of Queensland with
cloudy conditions and isolated showers. The upper trough is expected to move
across southern Queensland and most likely intensify into an upper level low,
leading to more unstable conditions over southeast districts and the southern
interior with generally scattered showers. The surface trough off the
Capricornia and southern Queensland coasts is likely to continue deepening as
the upper trough approaches, potentially with increasing winds and showers in
these areas, though there is some uncertainty associated with these developments
at this stage. Fine over most of the tropics, with only isolated light showers
over the far northern Peninsula district and developing about the North Tropical
Coast during the day. Minimum temperatures remaining a little below average in
parts of the eastern tropics. Maximum temperatures are expected to be generally
below average in the south and west due to cloud cover and the cool S to Se
airflow.
Outlook for Monday, Tuesday and Wednesday
The upper level trough and low should continue to strengthen and reach peak
intensity over central and southeastern Queensland late Monday and Tuesday,
before moving offshore during Wednesday. The high over South Australia is
expected to move slowly eastwards while weakening, but is expected to maintain a
moist southeasterly airflow into southern and central as the surface trough
continues to deepen near or off the southern Queensland coast. The deepening of
this trough is likely to lead to an increase in the onshore flow, with cloudy
conditions and increasing showers or rain over southeast Queensland,
particularly about the coast and adjacent inland areas. Forecasts for southeast
Queensland remain uncertain at this stage, with the intensity and extent of
these showers or rain being very dependent on the position of the surface
trough. The possibility of a significant low pressure system developing within
this trough off the southern Queensland coast remains in place. Cloudy
conditions with at least some showers are likely over the southern interior and
across parts of central Queensland. In the north, it should remain fine in most
areas, though some light showers are possible about the tropical east coast.
Maximum temperatures generally below average, particularly under cloud in
southeast and central Queensland.
The next routine forecast will be issued at 4:10 pm EST
Thursday.
