Australia -- Queensland Weather Update

MELBOURNE - Feb 20/12 - SNS -- The current forecast for the state of Queensland was released by Australia's Bureau of Meteorology.

Warning Summary at issue time
Flood Warnings are current for various rivers and
streams.

web site www.bom.gov.au/qld
Weather Situation
A surface trough extends from the northwest of the state to the New South
Wales coast. The coastal section of the trough and an associated cooler S'ly
wind change will move north along the far southern Queensland coast late today.
An upper level trough will also move over southeastern Queensland today. A deep,
moist E to NE wind flow extends over the far northern tropics.
Forecast for the rest of Tuesday
Showers and thunderstorms over southeast districts, mostly during the
afternoon and evening. Some thunderstorms are likely to be severe. Isolated
showers and thunderstorms over the southern and central interior between Emerald
and Charleville, increasing to scattered in the afternoon. Patchy rain and
thunderstorms easing to isolated showers over the southern border west of
Goondiwindi during the morning. Patchy, mostly light rain and isolated gusty
thunderstorms in the west. Scattered showers and thunderstorms over the northern
tropics. Isolated showers and thunderstorms elsewhere, mostly inland during the
afternoon. Light to moderate SE to NE winds through the northern tropics. A hot
day over much of the remainder of the state with moderate N to NW winds, fresh
at times along the southern coast ahead of a cooler, gusty S'ly change extending
from the south during the day.
Forecast for Wednesday
The surface trough will most likely reach Fraser Island early and then
weaken, with a general SE to NE wind flow extending along the east coast. The
upper trough will contract off the southeast coast, while a new upper trough
will intensify as it moves into southwestern Queensland. This new trough will
thicken a cloud band over parts of central and southern Queensland to its east,
resulting in rain areas, showers and thunderstorms. Showers and thunderstorms
will continue through the northern tropics in the deep E to NE wind flow.
Isolated showers and thunderstorms are expected over the central coast and
through the southern tropics.
Forecast for Thursday
Some uncertainty exists with the movement of the upper trough, but at this
stage it will most likely remain slow moving over southwestern Queensland and
intensify further into an upper low. Unstable conditions will subsequently
persist over much of the state, and should combine with a moist SE to NE wind
flow to produce fairly widespread showers and thunderstorms.
Forecast for Friday
The upper low will most likely retreat westwards into northeastern South
Australia. A moist and generally unstable airmass will persist over much of the
state, with showers and thunderstorms likely over many districts.
Outlook for Saturday, Sunday and Monday
The upper low will most likely move further south over southern Australia and
weaken. Shower and thunderstorm activity should therefore weaken over the
interior. A slow moving high over the Tasman Sea will extend a firm ridge on to
the east Queensland coast. The deep, moist SE to NE wind flow will maintain
shower activity on the east coast and adjacent inland, most likely more
widespread with thunderstorms north of about Gladstone.
The next routine forecast will be issued at 4:10 pm EST
Tuesday.
