National Weather Update 4 July 2024: Record cold morning and rain forecast for central Australia

 

Hi, it's Christie at the Bureau here to talk to you about the cold morning that we had this morning and also the rain that's expected to develop over central Australia over the next couple of days. 

 

So, starting with this morning's cold morning, we can see these widespread light blue and white areas showing very cold temperatures across much of the country.

 

Giles 0°C in Western Australia, Alice Springs -3°C down to -4°C almost in Ceduna.

These are all places that had their coldest morning of the year.

A July record for Warrnambool in Victoria -2.4°C and down in Tasmania topping the list, -13.5°C at Liawenee.

Very cold morning in Tasmania.

And what's causing that?

Well, it's been caused by this large high pressure system that's sitting to the south of the country, and that's not only driving cold Antarctic air up over the country, but also giving us clear skies and light winds, the perfect conditions for heat to escape overnight.

We can also see that that system is driving these showers right along the east coast with onshore flow being pushed from the water onto the coast.

We also have this system over South Australia and Queensland, which is driven by a large upper low pressure system that's developing and that's initially going to start over South Australia but extend into western Queensland and by the time we get to the end of the weekend, also into parts of New South Wales as well.

Finally, we have this cold front crossing south-western parts of Western Australia on Sunday.

So, how much rainfall are we expecting with all these weather systems?

Well, over in the west, mostly single digit rainfalls with that front that's crossing, a little bit more along the coast.

But over central Australia with that patchy rainfall, possibly some thunderstorms, maybe even some locally heavy falls with those thunderstorms, we could see widespread falls of 10-30 mm, maybe even some areas up over 50 mm.

And along the east coast, with those showers continuing most days over the rest of the week and the weekend, potentially again widespread single digit rainfall but closer to the coast, again, 10-30 mm, maybe even some places up over 50 mm, particularly about the North Tropical Coast and the Cassowary Coast in particular.

So, looking at our temperatures, we are expecting another cold morning tomorrow morning, but not quite as cold as we saw this morning.

Still some frost potential through central Australia, down to 0°C at Alice Springs.

Also possibly frosty over parts of Victoria and Tasmania.

There is a Road Weather Alert for Tasmania for icy roads.

So, take care if you're in that part of the world.

Daytime temperatures tomorrow mostly below average, particularly over central and western parts of the country, and also down the eastern seaboard where those showers and some cloud will keep the temperatures a little bit suppressed. For Saturday morning, we're looking at, once again, the risk of some frost over inland parts of Western Australia and also down over Victoria and Tasmania but we will see that cloud that's developing over central Australia with that shower activity keeping the temperatures just a little bit less cold than they have been.

And finally during the day on Saturday, we're once again expecting temperatures near or slightly below average.

And that's it for our weather update.

For your location, make sure you check out the Bureau's website or app, and we'll see you again soon.

Both ‘potential’ and ‘possibly’ are English words that indicate ‘possibility’, but each has a subtly different nuance.

‘Potential’ refers to the ‘possibility’ or ‘potential’ of something happening. For example, ‘frost potential’ means ‘the possibility of frost’.

On the other hand, ‘possibly’ conveys a sense of ‘perhaps’ or ‘maybe’, expressing the uncertainty that something might happen. For example, ‘possibly frosty’ would mean ‘it might frost’.

Therefore, these words are used differently depending on the context. ‘Potential’ is generally used to indicate that there is a possibility of something happening under certain situations or conditions. Meanwhile, ‘possibly’ is used to express the uncertainty that something might happen based on specific facts.

Both ‘slightly’ and ‘a little bit’ are English expressions that mean ‘a little’ or ‘slightly’, but they have subtle nuances.

‘Slightly’ means ‘a little’ or ‘slightly’, indicating that something is a little less or a little more than usual. For example, in the sentence ‘The temperature is slightly below average’, ‘slightly’ indicates that the temperature is ‘slightly’ lower than average.

On the other hand, ‘a little bit’ also means ‘a little’ or ‘slightly’, but this expression is more colloquial and is often used to indicate that something is ‘just a little’ different than usual. For example, in the sentence ‘I’m a little bit tired’, ‘a little bit’ indicates that the degree of tiredness is ‘just a little’.

 

 

Both ‘make sure’ and ‘just in case’ are English expressions used when checking or preparing something, but they are used in different situations.

‘Make sure’ means ‘to confirm’ or ‘to ensure’, and is used to make sure something is done correctly. For example, in the sentence ‘Make sure you lock the door’, ‘make sure’ indicates that you should ensure the door is locked.

On the other hand, ‘just in case’ means ‘for precaution’ or ‘in the event that’, and is used to prepare for the possibility of an unexpected situation or problem. For example, in the sentence ‘Take an umbrella, just in case it rains’, ‘just in case’ indicates that you should take an umbrella as a precaution against unexpected rain.

 

 

 

 

 

‘driving’ and ‘driven’ are used to represent the forces or factors causing meteorological phenomena and climate changes.

‘Driving’: This word means ‘propelling’ or ‘pushing forward’, indicating the force that causes other events or situations. For example, in ‘that’s not only driving cold Antarctic air up over the country’, ‘driving’ indicates that the high-pressure system is ‘propelling’ cold Antarctic air across the country.

‘Driven’: This word means ‘propelled’ or ‘pushed forward’, indicating that something is caused by other forces. For example, in ‘which is driven by a large upper low pressure system’, ‘driven’ indicates that it is ‘caused by a large upper low pressure system’.

Therefore, these words are frequently used in weather forecasts to explain the forces or factors causing climate and weather changes.
