Nation Swelters, Southern Storms Loom

Taking a look at tomorrow's weather map, we can see a couple of low-pressure troughs lying across the continent. The first, extending from central areas into the east, is driving very hot conditions, particularly across the Northern Territory, parts of New South Wales, and throughout Queensland.

A second low-pressure trough is moving from Western Australia into South Australia tomorrow, joining up with a cold front and low-pressure trough to produce wet and stormy weather across parts of central and southeastern Australia.

Further west, more settled weather is on the way, with cooler southerly flow pushing up across Western Australia.

Now, we've issued two other videos here at the Bureau today to better tell that weather story. The first is a severe weather update focused on the heat and elevated fire dangers expected across parts of northern and eastern Australia over the coming days. The second is a weather update focused on the wet and stormy weather brewing further south. If you want more detailed information on either of those stories, we recommend you check out our other videos.

For now, though, we're going to take a brief state-by-state look at tomorrow's forecast, starting with Queensland.

There is a chance of morning fog along the central and southeast Queensland coasts tomorrow, then a generally sunny and settled day. It will be very hot, with temperatures above average throughout the state, particularly through central and southern inland areas. Severe heatwave conditions are even building across far western parts of Queensland.

For Brisbane tomorrow, a sunny day is on the way with a top of 30 degrees.

In New South Wales, expect a hot and generally sunny day. Temperatures will be particularly high across the northern, inland, and northwest of the state. We are likely to see a few very light passing showers in the far south, and the chance of an afternoon thunderstorm across the central west and parts of the east coast between the Illawarra and the Mid-North Coast. These thunderstorms are likely to be isolated, non-severe, and not bring much rainfall.

For Sydney tomorrow, expect a mostly sunny day with a top of 23 degrees.

Down in Canberra, there may be a shower or two with a top of 30 degrees.

In Victoria, cloud and showers will build throughout the morning. Showers will tend to be scattered in the afternoon across the western districts with the chance of a thunderstorm there too. We may see double-digit rainfall totals across parts of the Wimmera and Southern Mallee tomorrow, with generally low rainfall totals elsewhere.

For Melbourne, expect a top of 20 degrees with showers developing.

In Tasmania, isolated showers will continue across western parts of the state, with generally dry conditions through the east. Winds will be fairly moderate. Tomorrow is a bit of a break from the wet and windy weather we've been seeing recently.

For Hobart tomorrow, expect a cloudy day with a top of 17 degrees.

In South Australia, showers, rain areas, and thunderstorms will extend throughout the state, driven by the low-pressure trough and cold front approaching. Ahead of the rain, very hot conditions are expected in the north and northeast, with cool to mild conditions further to the southeast. Rainfall totals are likely to be patchy across inland parts of the state, but moderate falls are possible across parts of the Eyre Peninsula and the southeast. There may also be damaging wind gusts or large hail in parts of the northwest pastoral region, possibly through the afternoon.

For Adelaide tomorrow, expect a top of 26 degrees with showers and a thunderstorm or two developing.

In Western Australia, isolated showers and thunderstorms will occur across the interior of the state, gradually easing back as the low-pressure trough moves into South Australia. Partly cloudy skies and a few showers are expected in the south, with generally dry conditions further inland.

For Perth, expect a partly cloudy day and a top of 21 degrees.

In the Northern Territory, hot conditions are expected with temperatures well above average in most places and heatwave conditions continuing around the Tiwi Islands and across parts of the west and Top End. It will be a bit drier for the Top End, with just a few light showers in the far west. Showers and thunderstorms are also possible from the Kimberley in Western Australia, pushing down across southwestern parts of the territory. They are unlikely to bring much rainfall but could produce some strong and gusty winds in the far southwest of the Northern Territory.

For Darwin tomorrow, expect a top of 36 degrees with mostly sunny skies.
