Hello, Miriam at the Bureau with your national weather forecast for tomorrow, Tuesday the 13th of January.

Taking a look at tomorrow's weather map, we can see several low pressure troughs around the country, through the west, the north and the east. Now, we are likely to see some thunderstorms around these low pressure troughs, but rainfall totals are really going to be focused through the north-east, through Queensland, where the risk of heavy falls and flooding is ongoing.

We may see some cooler than average conditions through parts of the far south-east tomorrow, but generally milder than average conditions elsewhere, with heat certainly starting to build across those northern and central parts of the continent.

Let's take a state-by-state look at tomorrow's forecast now, starting with Queensland.

Showers and storms are forecast across much of Queensland tomorrow, certainly through those northern, central and eastern areas. In the north, we've got the remnants of ex-Tropical Cyclone Koji moving through, likely to bring further heavy falls and the risk of flooding to those areas. This severe weather event is still ongoing, so we have issued a dedicated severe weather update video around this situation, where you can find all the details around the rain and the flooding.

But for Tuesday, we also have the risk of severe thunderstorms bringing locally heavy falls to parts of the south-east as well. That includes parts of the south-east coast, the Wide Bay and Burnett, and pushing across some of those inland areas as well. So flash flooding will be a risk where those storms do develop.

Cooler than average conditions are expected under that cloud and rain, while milder than average temperatures are expected across the southern inland and the far west. For Brisbane tomorrow, showers on the way with a top of 28 °C.

In New South Wales tomorrow, there is the chance of morning fog across some of our eastern districts. Partly cloudy through the east and mostly sunny elsewhere. We could see a few isolated showers moving through those eastern areas, with generally low rainfall totals expected.

We could also see a few isolated thunderstorms developing through the afternoon, mainly across the north-west slopes and plains, and parts of the far south-east too. Any storms tomorrow are likely to be non-severe and not bring too much rain to the gauges. For Sydney tomorrow, a mostly sunny day with a top of 29 °C.

Down in Canberra, mostly sunny with a top of 33 °C.

In Victoria tomorrow, we could see some areas of smoke persisting across the state, as well as some morning fog through parts of Gippsland. Then it will be a warm and mostly sunny day north of the ranges, cooler and cloudier in the south.

We could even see the chance of an isolated shower or two across parts of central Victoria and the Eastern Ranges through the afternoon. For Melbourne, it will be mostly dry, partly to mostly cloudy, with a top of 22 °C.

In Tasmania tomorrow, the chance of morning fog across some of those northern inland areas. Partly cloudy skies across the state, with the chance of a few showers moving through mainly in the afternoon and predominantly focused through those northern inland areas.

Temperatures generally within a few degrees of the average, slightly cooler in the east and far south. For Hobart tomorrow, partly cloudy skies and a top of 20 °C.

In South Australia tomorrow, warm and sunny across the state. Temperatures close to or above average statewide. It could feel a little bit fresher through some of those southern areas once an afternoon sea breeze kicks in. For Adelaide, a top of 31 °C, sunny and dry.

In Western Australia, hot to very hot temperatures are forecast through those northern and central parts in particular, with heatwaves building, including severe to locally extreme intensity heatwaves through some of those northern areas.

We are also likely to see high fire dangers across many of our western and southern districts, largely driven by fresh winds at times. A few isolated showers along the south coast, and the chance of thunderstorms extending from northern parts of Western Australia, through the Pilbara, those inland and central areas, down through the Goldfields and towards the south coast.

Storms are not likely to bring too much rainfall tomorrow, but they could produce some gusty to locally damaging winds at times. For Perth tomorrow, a mostly sunny day with a top of 30 °C.

In the Northern Territory tomorrow, hot to very hot conditions are expected throughout the Territory. Heatwaves are building, mostly focused through those central areas. Dry and sunny further south, but we could see the chance of a thunderstorm or two across the Top End.

For Darwin tomorrow, a shower or two, a possible thunderstorm, and a top of 33 °C.

Now, you can find the detailed forecast for your area via the Bureau’s website, the BOM Weather app, or via our social media. Have a great day, and we'll catch you next time.
