This weekend, a significant cold front will sweep across Australia’s eastern states, bringing unusually frigid Antarctic air and the potential for the coldest September weather in decades. Tasmania felt the initial effects overnight, with snow reported near sea level around Hobart, and the cold air mass is set to spread through Victoria and New South Wales today.
Frigid Conditions Expected Across Eastern States
The abrupt drop in temperatures is attributed to a powerful front arriving from the south, which is expected to deliver hail, snow, and chilly winds to southeastern regions. The Bureau of Meteorology anticipates temperatures could plummet by as much as 10 degrees below average, with Hobart struggling to reach highs of just 10°C, and potentially remaining below 9°C—the coldest spring day recorded so far this century. Similarly, Melbourne is likely to see Saturday temperatures hover around the 11°C mark, representing a significant drop for this time of year.
- Hobart: Forecast high of 10°C, possible record lows.
- Melbourne: Expected high between 11°C to 12°C, a 20-year low for spring.
- Sydney: Highs dropping to 17°C, the coldest in a month.
Snow and Hail: Impacts on Southern Regions
As the cold front pushes through, Tasmania will experience steady snowfall through Saturday, particularly affecting areas at elevations between 200 and 400 metres. Significant accumulations of at least 10cm are anticipated across the southern and western highlands, prompting the Bureau of Meteorology to issue warnings for road users in various districts.
Towns including Waratah, Fern Tree, Oatlands, and Bothwell are likely to see snow. Although Hobart usually stays sheltered from the harshest winter fronts due to the presence of Mt. Wellington, this front’s trajectory is set to bypass it, potentially allowing snowfall to reach Hobart’s higher suburbs.
In Victoria, the Gippsland region will be the primary recipient of cold air, with areas above 1,000 metres expected to receive 15cm of snow in the coming 24 hours. The snow is also anticipated to lower to around 600 metres in the eastern parts of the state. Moreover, snow will make its way to New South Wales, particularly in its southeastern regions, including Bombala, Nimmitabel, and Cooma, where the snowfall may touch elevations as low as 700 metres.
Forecast for the Upcoming Days
By Sunday, Tasmania and Victoria will continue to experience icy conditions. As the cold air moves northward, Sydney residents will face the chill with a forecasted high of just 17°C. The persistent southerly winds will create significant wind chill, making the temperatures feel several degrees cooler across many regions.
- Sunday Highlights: Cold air continues; regions likely to feel temperatures lower than reported highs.
- Winter Conditions: Heavier snowfall expected in mountain regions.
As the temperatures begin to rise into the following week, they will still remain well below average, with overnight lows plummeting in inland areas. Canberra could see a minimum of -4°C, approaching an all-time spring record.
Potential for Continued Cold Waves
The weather pattern is expected to bring another wave of polar air midweek, although this subsequent front is predicted to be less intense than the current one. Snowfall below 1,000 metres is still a possibility, particularly for Tasmania, where prolonged snowfall combined with expected constant rain could lead to further flooding issues.
Forecast models suggest Western Tasmania could receive over 100mm of rain and snow this week, elevating concerns for rapid river rises and possible flooding. As the season progresses, it is important for communities to remain vigilant about these changing weather conditions.
The Ski Season’s End in Sight
Despite the unexpected cold snap and snowfall in spring, the ski season appears to be winding down after a warmer-than-usual August melted much of the snow cover prematurely. Currently, only Perisher remains open for skiing, though access is limited to specific areas where snowmaking efforts have been employed.
While these recent cold fronts are notable, the forecast for the next weekend suggests that another strong front could arrive, potentially bringing additional wintry conditions. However, specifics on this second wave of cold air are still uncertain as weather patterns develop.
People in Australia’s south-eastern states should get ready for some winter weather this weekend. Snow, hail, and cooler temperatures are on the way. It might be a good time to stay cozy at home by the fire!
