National weather forecast: Front crosses south-east; storms for Qld

Another front crosses the south-east states, while storms contract north through Queensland on Wednesday, November 4th.

G’day from the Bureau. David here to take a look at the weather around the country for tomorrow, for Wednesday.

And what we’ll see is we’ll see these showers and storms off the New South Wales and Queensland coast. They’ll contract offshore in the early hours of Wednesday morning.

Then we’ll see a cold front sweep across the south-east states over the course of the day, bringing showers and gusty storms to the south-east.

We’ll see storms continue about parts of Central Queensland and up into the Top End, although those storms will be pushed north, north of this inland trough, by this large ridge of high pressure, which is coming in to dominate the weather through southern WA, through SA as well.

And as I say, pushing those showers and storms further north. It’s also really hot in northern Australia at the moment.

Temperatures up into the low to mid 40s across many parts of northern Australia. So heatwave warnings are in effect this week.

So let’s take a look around the grounds now, starting with Queensland, and in the south-east it’ll be a warm and dry and sunny day.

Brisbane going for a top of 33 degrees.

The trough will be moving north, taking the showers and storms with it up to Wide Bay, Capricornia and Central Queensland, so severe storms are possible in the afternoon through those areas, with damaging winds, large hail and heavy rain all a threat.

But much clearer skies through southern Queensland after Tuesday’s thunderstorm outbreak, warming right up in the west and the north, reaching the low 40s in western Queensland and the high 30s up on Cape York.

So a heatwave warning for severe heatwave conditions is in effect for the Cape York Peninsula, where it is getting unseasonably hot.

For New South Wales and the ACT, we’ll see again the showers and storms move off the coast in the early hours of Wednesday morning.

So much of eastern New South Wales, there’ll be a few showers around during the day on Wednesday, but it’ll be largely a dry day.

And then in the west, in the south, we’ll see these showers and storms increase and move east over the course of the day, reaching Canberra in the evening, where it’ll be a top of 24 degrees, and then some showers in the evening.

Sydney mostly dry for the most part, 25 degrees, and then maybe some showers reaching there in the very late evening.

In Victoria, it’ll be a windy day, both ahead of and behind this cold front, which we’ll see come into frame here.

Showers and thunderstorms will extend from the west during the day, reaching Melbourne in the early afternoon, most likely bringing the risk of some damaging winds, with severe thunderstorms through parts of western Victoria, including around Horsham and the Wimmera in particular, and showers gradually contracting east later in the day.

Quite cool behind the front too, with snow above about 1,400 metres on the Alps later in the day on Wednesday.

For Tasmania, similar story, starting off mostly sunny and then we’ll see cloud increasing and rain and showers developing from the west during the day.

Hobart, a sunny start and then showers in the afternoon, with a top of 21 degrees, and again getting quite cold behind this system.

Snow falling above about 1,100 metres later in the day on Wednesday.

For South Australia, a very different story across the state.

Showers and a few thunderstorms and gusty winds in the south.

Quite cool, with a top of 17 degrees in Mount Gambier, Adelaide at a top of 21 degrees.

Showers reaching there in the late morning and then clearing up quickly through the afternoon.

Quite windy, as I said, right through southern South Australia, up through the gulfs as well. And that’s because of the temperature gradient.

Look at the different temperatures here: 17 degrees in Mount Gambier and as high as 38, 39 degrees up in Marree in the North-East Pastoral district.

So that extreme temperature gradient across the length of South Australia, that’s what creates the windy conditions, particularly through the Spencer Gulf at this time of year, where the sea breeze can really roar in from the south through Port Augusta and Whyalla.

For Western Australia, we’ll see a high-pressure system come into frame here. That’s going to be the dominant system.

A little bit of morning fog inland, but then a beautiful sunny day right across southern WA, Perth warming up with a sunny top of 27 degrees and really pleasant conditions across the board there. A different story as we get further north, though, through northern WA.

Extreme heatwave conditions for some of the districts in northern WA, and heatwave conditions also for parts of the Northern Territory, where, as you can see, temperatures are nudging 40 degrees, even up into the mid 40s through inland parts of the Pilbara on Wednesday.

So really warm to hot to very hot indeed through the Northern Territory and northern WA. Showers and storms north of the trough line, so Tennant Creek and north generally.

Darwin, partly cloudy, with a top of 35 degrees. Just a slight chance of a shower or storm on Wednesday.
