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 surface trough extends from the northern Gulf Country to Yeppoon. An upper
trough is expected to move east off the southern Queensland coast during today.
A deep low pressure system offshore of the New South Wales coast will move north
during today and approach far southern Queensland waters early Sunday before
shifting east into the Coral Sea. This will extend an increasing S'ly swell
through southern exposed waters during the weekend.  A high [1037 hPa] south of
Tasmania extends a ridge over western Queensland and the southern interior.
Forecast for the rest of Saturday
Partly cloudy with scattered showers and isolated gusty thunderstorms over
central districts north of about Clermont and the far southeast tropics.
Isolated showers and possible thunderstorms over the northeastern Gulf Country.
Isolated showers and possible thunderstorms through Torres Strait, contracting
northeast during the day. A cool day through southern Queensland, with possible
early light frost patches about the Maranoa and the Darling Downs and Granite
Belt districts. Moderate to fresh and gusty SW to SE winds southwest of a line
from Kowanyama to Yeppoon. Moderate SE to NE winds through the northern
Peninsula. Light and variable winds elsewhere. A Very High fire danger in the
Northwest district.
Forecast for Sunday
The surface trough lying from the Gulf Country to central Queensland is
likely to weaken, but is still expected to generate isolated showers over parts
of central Queensland and the far eastern tropics. Isolated light showers are
also expected over the southern Peninsula and northeastern Gulf Country. Another
cool morning is expected in western, southern and central inland parts
Queensland, with possible early light frost about the Maranoa and the Darling
Downs and Granite Belt districts. The next upper trough is expected to extend
high cloud across far southern Queensland during the day though with little
rainfall expected.
Forecast for Monday
The upper trough will move rapidly east across southern Queensland, while
another will approach the southwest border at night. This will maintain areas of
cloud over southern Queensland though little rainfall is expected. A new surface
trough is expected to move across the central and southern Queensland interior.
This surface trough will most likely be assisted by the upper trough to generate
isolated showers over central districts. A trough and associated shower and
thunderstorm activity through northeast stretches of Torres Strait will start to
shift southwest towards Cape York Peninsula. Mostly fine conditions are expected
along the northeast tropical coast with just the chance of isolated light
showers. Maximum temperatures will be above average across most of the interior
ahead of the surface trough, particularly in the northwest.
Forecast for Tuesday
The new upper trough and surface trough are both expected to move east into
eastern Queensland, with scattered showers and gusty thunderstorms over central
and southeast Queensland in the afternoon and evening, mostly over areas south
of about Yeppoon. Showers and isolated thunderstorms are expected over far
northern Cape York Peninsula and Torres Strait in a moist and unstable airmass.
The high cloud over western Queensland and the southern interior is likely to
generate some patchy light rain, with maximum temperatures generally below
average in this area. Maximum temperatures will remain generally above average
through remaining parts of the state.
Outlook for Wednesday, Thursday and Friday
A series of upper troughs are expected to move east over the south of the
state. The surface trough is expected to  contract off the far southern coast
during Wednesday and shift north into central districts, during Thursday,
gradually contracting the area of showers and isolated thunderstorms into
central Queensland and the southeast tropics. A new ridge is expected to develop
along the southern Queensland coast from Thursday with isolated showers near the
coast in the onshore wind flow. This ridge will then extend along the remainder
of the east coast by the end of the week with isolated to scattered showers
about most east coastal districts. Cloud will most likely increase through
western Queensland again from late Thursday ahead of a new upper trough
developing over central Australia, with the possibility of patchy light rain.
Widespread showers and isolated storms will persist through northern Cape York
Peninsula and Torres Strait in a moist and unstable airmass. Temperatures will
remain generally a little below average in the southwest, and near or slightly
above average elsewhere.
The next routine forecast will be issued at 4:10 pm EST
Saturday.
