Forecast issued at 5:17 am EST on Thursday 28 August 2014.
A low pressure system centred over the northern Tasman Sea extends a trough westward to a small low circulation off the NSW north coast. The small low is moving towards the northwest and is expected to pass near the far northern NSW/southeast Queensland coast this morning before moving away to the northeast later in the day. A ridge of high pressure lies across the southern Tasman Sea cradling these systems and producing southeasterly winds over NSW. A low pressure centre is likely to remain over the central Tasman Sea through to the weekend, then gradually move towards New Zealand as a weak ridge develops over New South Wales. The next cold front is forecast to move across the region early next week.
