Weather News - Cold change roars through NSW as southeast QLD bakesRob Sharpe, 2 September 2014
A cold change is sweeping through New South Wales today and it can be seen like never before on the new Weatherzone homepage.
A front and trough is moving through northeastern NSW today, bringing showers, a few thunderstorms and cooler southwesterly winds. The system crossed through Sydney this morning, but the strongest winds are yet to come.
A low pressure system is developing in the Tasman Sea today and is already producing gusty winds and rain in Victoria. As this low intensifies and travels north along the NSW coast it will produce powerful winds and plenty of showers. This low has prompted a severe weather warning for the coastal fringe of the Illawarra, Sydney, Hunter and Mid North Coast. Wind gusts are could reach 100km/h tonight or on Wednesday morning due to the strong pressure difference between the low offshore and the high over the mainland.
Meanwhile, in Queensland, warm northwesterly winds are spreading into the southeast of the state ahead of the front and trough. The gusty and dry nature of these winds have sparked a fire weather warning for the Southeast Coast district. Brisbane is likely to see its warmest day since April, with a forecast maximum of 29 degrees, making many Australians further south a bit jealous.
Wherever you are in Australia you can now see the affects of this complex system on the new Weatherzone homepage using the zoom map. This map shows the isobars and forecasts for today and tomorrow as well as live radar, satellite and observations for the whole nation.

Weather News - Wintry blast to bring snow to NSW rangesBrett Dutschke, 1 September 2014
A wintry blast is about to drop temperatures by as much as 10 degrees across New South Wales and also bring snow to the ranges, as far north as the Queensland border.
A cold front will cross the west and south of NSW during Monday and the rest of the state during Tuesday, bringing showers, small hail and mountain snow.
Snow should fall right along the ranges, developing in the south during Monday night, central parts on Tuesday morning and northern parts on Tuesday evening, possibly even reaching far southern Queensland at night.
Snow is only a small risk for most towns given that is likely to generally fall above about 1200 metres.
Guyra, on the Northern Tablelands, has a higher chance than most towns, being about 1300 metres above sea level.
Snow in Guyra during September occurs once every two or three years and last occurred in 2011.
During Wednesday the cold, unstable air will move off the coast, allowing inland NSW to dry out fairly quickly.

Weather News - Spring starting damp in WABrett Dutschke, 2 September 2014
The Southwest Land Division is starting spring as winter ended, wet, helping grain crops recover after a drier-than-normal winter
The Southwest Land Division dried out during August then picked up reasonable rain at the end of the month and is about to get spring off to a wet start, giving grain farmers some hope.
Most of the region had a drier-than-average winter and could do with some rain to help grain crops continue their recovery. It was a short winter with most places seeing above average rainfall during July. Only a few small areas in the Division, including Bridgetown, Jacup, Katanning and Lake Grace, ended up with a wetter than average season.
Between now and this time next week low pressure troughs will form over the region and draw moisture from the Indian Ocean to scatter rain over a large area.
One system will slowly move through between now and Thursday and another stronger system will do a more effective job over the weekend and early next week.
All up, rain will reach north of Carnarvon and as far east as Eucla and fill almost all the gaps in between, including the wheat belt, where it is still badly needed. Some of the wheat belt only gained less than one millimetre late last week while the Donnybrook area flooded.
All up during the next week the heaviest falls will be near the west coast, widespread 10-to-30mm. There is potential for the odd 50mm-plus-total south of Perth, most likely in the Bunbury-Donnybrook area.
Rain will become lighter as it travels east with eastern parts of the wheat belt likely to gain less than 10mm.
One of the areas most desperate for rain is Bencubbin and Merredin which only picked up just over half their winter average of 130mm. These areas typically gain 20-to-25mm during September and should pick up 10-to-20mm in the coming week.
Looking further ahead, computer models indicate potential for some follow-up rain during the following week, taking much of the region close to its September average.
The next few weeks are critical given we are entering a dry time of year and this spring looks like it will end up drier than normal.
