Australia -- Queensland Weather Update

MELBOURNE - Jun 27/13 - 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 north of New Zealand extends a surface trough into southern Queensland.
An upper level trough moving across southern Queensland is expected to move
offshore on Friday. A new high is expected to strengthen over the Great
Australian Bight on Friday, maintaining a moist S to SE flow into southern
Queensland.
Forecast for the rest of Thursday
Cloudy with scattered and areas of rain over southeast districts and the
southern interior. 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.
Forecast for Friday
Cloudy over the southern half of the state, with scattered showers and
drizzle areas over southeast districts and the southern interior and areas of
morning rain over the southeast. Isolated light showers over the far
northeastern Peninsula District. A cool morning in central districts. Light to
moderate SW to SE winds, fresh at times in the north and northwest.
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 generally isolated to scattered showers. The upper trough is
expected to move across New South Wales and towards southwest Queensland, and
will help to deepen the surface trough off the southern Queensland coast. This
will also 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 scattered showers and isolated thunderstorms. The surface trough
off the southern Queensland coast is likely to continue deepening as the upper
trough approaches, with a low likely to have formed within the trough near or
off the coast. This is likely to increase winds with at least widespread showers
and possibly rain about Fraser Island, the Wide Bay and the Southeast Coast
district. Moderate falls are likely, though there is still some uncertainty
associated with the development and position of the low. Fine over most of the
tropics, with only isolated light showers over the far northeast Peninsula
district. 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.
Forecast for Monday
The upper level trough and low should continue to strengthen and reach peak
intensity over central and southeastern Queensland. The surface low pressure
system is likely to drift slowly southwards near or off the southeast Queensland
coast with widespread showers and/or rain areas from the Wide Bay and across the
Southeast district, and into the eastern Darling Downs and Granite Belt.
Moderate to possibly heavy falls may occur about the Southeast Coast and nearby
ranges, though the intensity and extent of these falls will be very dependent on
the position of the low. Cloudy with scattered showers and areas of rain over
the remainder of the Darling Downs, with more isolated showers and drizzle areas
over the eastern Warrego and Maranoa and parts of central Queensland as the high
over South Australia maintains a moist SE airflow into these areas. Isolated
showers along the northeast tropical coast. Maximum temperatures are expected to
be generally below average across the state due to a combination of cloud cover
and the cool S to SE airflow.
Outlook for Tuesday, Wednesday and Thursday
The high over southeast Australia is expected to weaken. The upper level
trough and low is expected to lie over southeastern Queensland on Tuesday,
before moving southeast and offshore on Wednesday. At this stage, some computer
models are suggesting that the surface low pressure system near or off the
southeast Queensland coast is likely to continue drifting southwards, with the
accompanying showers and areas of rain about the southeast contracting
southwards by early Wednesday, with isolated showers in its wake. However,
forecasts for southeast Queensland still remain uncertain, with the intensity
and extent of these showers or rain being very dependent on the position of the
low pressure system. In the north, it should remain fine in most areas, though
some light showers are possible about the northeast tropical coast. Conditions
are expected to be mostly fine across Queensland on Thursday.
The next routine forecast will be issued at 4:45 am EST
Friday.
