00:00Windy conditions and thunderstorms are already building across eastern Australia,

00:04with damaging wind gusts and severe thunderstorms a risk through the rest of today into Saturday.

00:11This windy, stormy weather is being driven by a cold front which is moving across the

00:15Great Australian Bight. Ahead of that cold front, we're seeing clouds, showers and thunderstorms

00:21already building through eastern Australia. Behind the cold front, cold air will move in

00:26across the later part of the weekend. Now we've already got severe weather warnings for damaging

00:31winds current for three states, New South Wales, Victoria and Tasmania. For New South Wales and

00:37Tasmania, the warning covers southern parts of the state and that risk is most likely from later today,

00:44going into this evening. Across Victoria though, we may see some damaging wind gusts through the course

00:49of today as well. And it's worth noting that our warning area includes parts of Melbourne and the

00:55Mornington Peninsula, as well as our exposed coasts and elevated areas. Now let's take a look at how

01:02that cold front moves through. So as it approaches the southeast today, showers, thunderstorms and

01:08strong winds will continue across the eastern states, from southern Queensland all the way down to

01:12Tasmania, pushing back into parts of central Australia and northern parts of South Australia as well.

01:19The cold front itself should reach southeast South Australia early this evening, reaching Hobart and

01:24Melbourne through the later part of this evening. We'll see a change in wind direction at that time and

01:29another burst of showery weather. As we go into tomorrow, the cold front will start to move off

01:35the east coast, with wet and stormy weather contracting to northeast New South Wales and southeast Queensland.

01:42We're likely to see showers and breezy conditions continuing in the far south as a follow-up cold front

01:47moves through, but much drier weather will return to much of New South Wales and Queensland.

01:53Thunderstorms will really be a huge driving factor in our rainfall over the next couple of days,

01:58so let's break down the thunderstorm forecast for today and tomorrow. Now for today, storms are

02:03possible in our green areas, so stretching multiple states through the east, parts of central Australia as

02:08well. Now we've got several yellow areas on this map showing us where severe thunderstorms are possible.

02:14For the most part, those severe storms are likely through this afternoon, but across these coastal

02:20parts of the southeast, those severe storms are more likely later this evening as the cold front moves

02:25through. Now any severe thunderstorms today are likely to bring us the risk of damaging wind gusts

02:31as they move through. We could also see some large hail through parts of southeast inland Queensland and

02:36northeast inland New South Wales, as well as across inland parts of the southeast this afternoon.

02:43As we move into tomorrow and our cold front moves offshore, we're going to see the storm risk

02:48contracting to northeast New South Wales and southeast Queensland. Now Brisbane may see some storms

02:53tomorrow, but the risk of severe storms is more likely across southern inland Queensland, pushing down

02:59towards the mid-north coast. Again, damaging wind gusts and large hail will be possible with severe storms

03:04tomorrow, but we could also see some locally heavy rain that could lead to flash flooding.

03:10So between the risk of damaging winds and severe thunderstorms, we've got a number of severe

03:15weather impacts to be aware of over the coming days. We could see damage to trees and property as the

03:20strong winds or hail move through. Dangerous driving conditions are likely across eastern Australia

03:26as dangerous crosswinds develop or storm debris moves over the roads. We could also see some

03:31disruptions to transport and utilities through our cities as the strong winds potentially cause some

03:37damage. To finish off with, I want to take a quick look at the temperatures over the next few days

03:43to see the cold air moving in behind the front. Now today, our maximum temperatures are still reasonably

03:48mild, particularly through those eastern areas, high teens through southern South Australia and Tasmania.

03:54But as the cool air sweeps in over the weekend behind the cold front, we'll see those temperatures drop.

04:00That cool air will actually push up into southern Queensland and central Australia through the

04:04later part of the weekend as well. Now, as the temperature drops, small hail will become a risk

04:09with showers in the far south and the snow level will lower as well. By the end of the weekend into

04:14early next week, the snow level will likely be as low as four or five hundred meters in Tasmania,

04:20around 900 meters in the southeast alpine areas.

04:23So with strong winds, severe thunderstorms and then a cold outbreak to come over the next few days,

04:30it's essential to stay on top of the latest forecasts and warnings via the Bureau's website,

04:35the BOM Weather app and via our social media. Stay safe and we'll catch you next time.
