COME on Big Trev! 

The Bureau of Meteorology has produced arguably the most important weather forecast map of 2019, showing widespread rain for some of Queensland's most desperate areas.

BOM's eight day forecast shows 50mm-plus falls for the eastern half of the drought stricken Northern Territory and a big part of South West Queensland.

The bureau's forecast shows Tropical Cyclone Trevor located over the northeast Gulf of Carpentaria is dominating the weather.

"The system is likely to continue to reintensify rapidly and is expected to take a more southwestward track across the Gulf, making landfall over the southwest Gulf coast most likely on Saturday," the BOM forecast reads.

"A surface trough extends from north west Queensland, through the central interior to the far south east of the state. The trough will start to move slowly westwards today over southern parts of the state and will combine with moist air to its east to lead to mostly isolated showers and thunderstorms.

Then Cyclone Trevor is forecast to continue to move away from Queensland, possibly making landfall over the southeast Top End in Northern Territory.

By Sunday a surface trough over the southern parts of the state will combine with a new upper trough over the central Australia to lead to isolated showers and thunderstorms over the southern parts of the state, BOM says.

On Monday the new upper trough will strengthen and move eastwards combining with a surface trough over the southern and central interior as well as possibly the remnants of tropical cyclone Trevor, BOM says.

"This leads to showers, thunderstorms and rain areas over south western and western districts. Isolated showers and thunderstorms over northern Queensland. Maximum temperatures will cool in the west and south west as cloud cover and precipitation increases."

BOM qualifies the forecast maps saying they are produced from computer models and contain no input from weather forecasters.

Fingers (and toes) crossed the machines have it right.
