Australians in the southeastern states are bracing for a significant cold snap this weekend, as a powerful Antarctic air mass plunges temperatures across Victoria, Tasmania, and New South Wales. This weather pattern is expected to deliver the coldest September weather seen in decades, with forecasts indicating maximum temperatures 3 to 10 degrees below average for this time of year.
Cold Front Sweeps Across Southeast Australia
The frigid weather is already making its presence felt in Tasmania, where overnight conditions brought snow to near sea level around Hobart. Now, the cold front is advancing into Victoria, and residents are preparing for a drop in temperatures that could break long-standing records. According to meteorological data, cities including Hobart may struggle to reach highs of just 10 degrees Celsius, potentially marking the coldest September day so far this century. Similarly, Melbourne is projected to see maximum temperatures only reaching between 11 and 12 degrees Celsius, which would set a new 20-year low for September days.
Impact on Daily Life
With the temperature forecast indicating that the wind chill will make it feel even colder, many residents are advised to stay indoors during peak chill hours. The Bureau of Meteorology has also warned of the possibility of showers, small hail, and isolated thunderstorms throughout southern Victoria and Tasmania. While severe storms are not anticipated, there is a risk of significant hail accumulation on the ground.
Snowfall Expected Across Multiple Regions
As the cold front progresses, it is expected to bring widespread snowfall to parts of Tasmania and Victoria. In Tasmania, consistent snowfall is anticipated, with elevations of 200 to 400 meters expected to receive at least 10 centimeters of snow. Towns like Waratah, Fern Tree, Oatlands, and Bothwell are likely to be affected. The trajectory of the incoming cold air is favorable for snow in Hobart’s higher suburbs, despite the city often being shielded by Mt. Wellington.
On the mainland, Victoria’s Gippsland region will see significant snow, particularly in areas above 1,000 meters, where accumulations of up to 15 centimeters are possible. Snow may also reach lower elevations, potentially dusting areas down to 600 meters.
Effects on New South Wales
In New South Wales, the heaviest snowfall is expected to occur on Saturday evening in the southeastern regions, such as Bombala, Nimmitabel, and Cooma, where snow levels could drop to around 700 meters. While Sunday will see a slight easing of snow, flurries may still extend into northern parts of the state, up to the Barrington Tops.
Long-Term Weather Outlook
After this weekend’s cold snap, temperatures are expected to rise slightly in the week ahead, with milder conditions set to return by midweek. However, meteorologists caution that this warmth may be short-lived. A second wave of polar air is forecast to move across the southeastern states later in the week, bringing additional snow below 1,000 meters and potential flooding in Tasmania due to persistent rain at lower elevations.
Meteorological models predict that western Tasmania could receive over 100 millimeters of rain throughout the week, raising concerns of rapid river rises and further flooding.
Possible Third Cold Front
Looking ahead, another powerful front could approach southeast Australia next weekend. While precise forecasts are still being developed due to the distance of this potential weather system, it could bring another wave of chilly weather, snow, and wintry showers.
The current weather conditions serve as a stark reminder of the variability that spring can bring, with the blustery cold temperatures contrasting sharply with the warmer climate that is usually expected at this time of year.
As the cold weather approaches, officials are reminding everyone to stay safe. If you’re going to be traveling in places where a lot of snow is expected, make sure to take extra care.
