Forecast issued at 4:15 pm EST on Tuesday 17 January 2017.
A high in the Tasman Sea extends a ridge over southeast Queensland and along much of the east coast, whilst an area of low pressure over the Northern Territory will move westwards over the next few days. A moist and unstable air mass extends over the north and west of the state, though the focus for storm activity and heavy falls will largely focus about the Gulf Country and far north of the state. A broad area of low pressure will gradually extend into the southern half of the state mid to late week, resulting in heat wave conditions developing in parts of southern Queensland, extending into central districts and throughout the southeast quarter of the state. Instability and the chance of storms will gradually increase through southern districts from mid-week with showers and storms becoming increasing likely.
