A cold front is sweeping across southeastern Australia, affecting Victoria, New South Wales, the Australian Capital Territory, and Tasmania with plunging temperatures, strong winds, and snow in high country areas like southern NSW and Victoria's high country. Temperatures are expected to drop sharply; for instance, Hobart will reach a maximum of 12°C on Tuesday while Sydney is forecast to have a low of 10°C on Thursday. Strong gale warnings have been issued for parts of Victoria’s East Gippsland coast and Tasmania’s west coast. Perth will experience warmer conditions initially, reaching up to 30°C on Wednesday before cooling down with potential thunderstorms developing later in the week.

Story summary
A cold front is sweeping across south-eastern Australia, causing temperatures to drop sharply. Victoria, NSW, the ACT, and Tasmania will experience icy conditions, strong winds, and light snowfall in some areas. Temperatures that were as high as the mid-20s last week are now expected to plummet. For instance, Hobart is forecasted to reach a maximum of only 12°C on Tuesday, while Melbourne will peak at 13°C on Wednesday. Strong winds are anticipated along the East Gippsland coast in Victoria and western Tasmania, prompting gale warnings from the Bureau of Meteorology. By Wednesday, the cold front will extend into NSW and the ACT, with Sydney expected to reach a maximum of just 18°C and Canberra peaking at 13°C, with a low of -1°C on Thursday morning in Canberra. Weatherzone journalist Anthony Sharwood predicts light snowfall at elevations above 800 meters in Victoria's high country and southern NSW.
