Weather News - Cloud teasing SA but rain still a way offBrett Dutschke, 2 March 2015
South Australia is enduring one of its longest dry spells in years and despite cloud moving in from the northwest today, significant rain relief is a long way off.
Cloud streaming in from Western Australia is only bringing a few spots of light rain east of the Nullarbor due to an area of high pressure over the region.
A weak low pressure trough is struggling to develop over SA and should only bring decent falls to the Nullarbor and Great Victorian Desert during the next few days.
High pressure should remain dominant over the south of the state for at least another week, possibly two. Every few days a weak front is only going to deliver a few millimetres of rain south of about Adelaide while the earth further north ramins dry and cracked.
Lameroo, Kadina, Whyalla and Port Augusta have recorded any rain since mid-January, seven weeks ago. Some northern Adelaide suburbs and parts of the Mid North have not recorded rain in six weeks.
Adelaide itself has only gained one millimetre in the past 46 days, its longest spell with so little rain in eight years.
There is a chance that the city will fail to record anything in the gauge this Thursday and Saturday when two weak fronts pass and the next best chance may be another week away.
It may turn out to be the city's longest spell with so little rain in 13 years. In early 2002 Adelaide endured 62 days with a total of only one millimetre.
This is typically the driest time of the year but it is currently drier than the same time last year. It's as if the tap was switched off in mid-January. Gardens, parks and dams are all suffering despite near-average rainfall during the first half of summer.
Mt Bold, Adelaide's largest dam, is down to 45 percent capacity, its lowest level since winter 2013.

Weather News - Brisbane will turn up the heatRob Sharpe, 3 March 2015
Southeast Queensland has remained mild of late, but on Thursday the thermostat will be cranked to very high.
Heatwave conditions are lingering over western QLD at the moment, with some locations such as Birdsville and Longreach consistently reaching into the 40's, more than five degrees above average for more than 10 days.
This heat that has been lingering in the west for so long will finally surge into the southeast this Thursday. Ipswich is forecast to hit 39 degrees, which would be its hottest March day since 2007.
From the Gold Coast to the Sunshine Coast the seabreeze will limit the rising of the mercury, but it will help the humidity soar, making it feel a few degrees hotter than the temperature would suggest. In Brisbane's CBD the seabreeze should be coming in the middle of the day, but there is an outside chance that westerlies will hold it out long enough for the temperature to soar into the high 30's. This means the March record of 38.8 is at risk.
The hot and humid day will see office workers stay inside during lunch and those with free time flocking to the beaches.
A strong cool change will finally arrive in the evening. This change will also bring the end of the heatwave for western QLD bringing cooler southerly winds through most of the state. Most will be relieved to know that any future warmth spreading across the state this season won't be nearly as intense as this spell.

Weather News - Inland NSW and QLD sweat through an early autumn heatwaveAnthony Duke, 3 March 2015
Parts of southwest QLD and northwest NSW have seen and will see some very hot temperatures considering the summer season is over.
Bedourie in the QLD Channel Country reached 44.3 degrees on Monday. With the temperature set to reach above 40 degrees each day until Thursday, its likely to have seen its hottest March spell in at least 17 years.
Towns across the Upper Western of NSW are also likely to see their hottest March run of days in over a decade. By Wednesday afternoon, Brewarrina's five day average maxima is likely to be 40 degrees and its hottest March spell in 15 years.
Even the clear skies overnight won't bring much relief from the heat as temperatures threaten to remain five-to-eight degrees above the March average. Infact parts of western QLD is not likely to cool below 30 degrees until Friday morning.
The heat has been building for some days now over central Australia, meanwhile cold fronts crossing the southeast have pushed the heat north. On Wednesday evening and overnight, winds will turn southerly bringing cooler air to southwestern QLD. This should bring a few days relief, especially overnight. However, the heat should make a brief return at the start of next week.
