Weather Situation
A high pressure system [1025 hPa] west of Tasmania is moving slowly east and
strengthening. A trough lies off the north tropical Queensland coast, while
another trough lies over the Queensland interior. An intensifying upper level
trough lies over far western Queensland.
Forecast for the rest of Tuesday
Scattered showers and thunderstorms over the northeast tropics with moderate
falls. Areas of rain and thunderstorms from the southern tropical coast into
central districts and the southern interior east of about Charters Towers to
Cunnamulla with some moderate to heavy falls. Isolated showers over the far
southeast corner, increasing this evening with possible isolated thunderstorms
over the eastern Darling Downs. Mostly fine in the west, just the chance of
isolated showers over the Warrego and southern Channel Country. A cool day over
most of the interior. Mostly moderate SE to NE winds, shifting SW to SE over the
west.
Forecast for Wednesday
The inland surface trough should move west in response to the ridge
strengthening off the southern Queensland coast. The upper level trough is
expected to tilt towards the southeast, extending cloudy conditions and thundery
rain areas over southeastern districts with some moderate falls. Thundery rain
over central districts is expected to ease to showers and isolated thunderstorms
during the day as the trough tilts south. Showers and storms will continue over
the tropics. Showers and isolated storms over remaining parts east of about
Normanton to Cunnamulla. Mostly fine elsewhere, just the chance of isolated
showers over the southern Channel Country.  Moderate SE to NE winds over the
eastern half of the state, freshening about the coast south of about Bowen as
the high intensifies further in the Tasman Sea. Light to moderate SW to SE winds
in the west. Cool daytime temperatures over much of the state.
Forecast for Thursday
The inland surface trough is expected to move a little further west as the
high in the Tasman Sea continues to build a ridge along the east Queensland
coast. The upper level trough should weaken over the southeast with early
thundery rain areas easing to showers in the afternoon. Some instability
persists with possible isolated afternoon thunderstorms over the southeastern
interior. Showers and thunderstorms elsewhere over the state east of about
Burketown to Cunnamulla, with the thunderstorms occurring chiefly inland. Mostly
fine elsewhere with just the chance of isolated showers and late thunderstorms
over the eastern Channel Country and northwest due to the surface trough
shifting west. Light to moderate SW to SE winds in the far west. Moderate SE to
NE winds elsewhere, fresh at times along the southern and central coasts.
Forecast for Friday
The high will remain slow moving over the Tasman Sea though will start to
weaken later in the day. A surface trough will persist through southwestern
Queensland while a new upper level trough will move over western Queensland.
Unstable conditions should therefore persist through much of the state to the
east of the surface trough, with scattered showers and isolated thunderstorms,
tending to thundery rain at times from the southern tropics through central
districts and the southern interior with possible moderate to locally heavy
falls. Isolated showers and early drizzle areas in the southeast. Mostly fine in
the far west with just the chance of isolated showers or afternoon
thunderstorms. Moderate SE to NE winds across the state, fresh at times along
the coast south of about Bowen.
Forecast for Saturday
The high will continue to weaken over the southern Tasman Sea. The upper
level trough moves east over the state while another trough system is expected
to intensify over the Great Australian Bight. Rain areas and thunderstorms
should persist over central districts and the southern interior east of
Charleville, easing from the west during the day as the upper trough shifts
east. Remaining unstable through the tropics with scattered showers and
thunderstorms, chiefly during the afternoon and evening. Isolated showers over
the southeast, increasing to rain at times north of the Sunshine Coast. Mostly
fine in the west with just the chance of isolated afternoon and evening showers
and thunderstorms. Light to moderate SE to NE winds, fresh at times about the
coast south of Bowen.
Outlook for Sunday, Monday and Tuesday
The high will remain slow moving and weaken further over the southern Tasman
Sea. Some uncertainty exists with the movement of a trough system over the Great
Australian Bight but the most likely scenario is for it to intensify further and
move slowly east. A broad area of instability and associated shower and
thunderstorm activity should therefore continue to extend over northern, central
and western parts of the state. Generally isolated showers persisting about the
southeast. Cool daytime temperatures continuing, particularly over the southern
and central interior.
The next routine forecast will be issued at 4:45 am EST
Wednesday.
