Scorching temperatures will seem a world away in VIC and TAS on Saturday, with snow even a chance for the Tasmanian peaks. A strong cold front will plunge temperatures in southeastern Australia on Saturday causing some to start searching for their winter clothes. Melbourne is looking at only reaching 22 degrees across the weekend as southwesterly winds gust above 60km/h at times. The cool winds will also deliver a few showers, convincing many that autumn has arrived. In Tasmania, the change in season will be even more noticeable, with Hobart only looking at a top of 17 degrees across the weekend. This will be a stark contrast the the 36.6 degrees experienced on Tuesday, which was just shy of a March record. Elsewhere in Tasmania, mountain peaks should experience snow falling as low as 1000 metres on Saturday night as the temperature plummets. Saturday and Sunday night will be two of the coolest in months for Australia's southeast. Canberra is heading for its coldest night since December with a forecast minimum of just 5 degrees for Sunday night. For those who were enjoying the summer heat there are still another few weaker bursts of warm weather to come. Melbourne should tip 30 degrees again on Wednesday or Thursday next week with another chance a week later. However, as the days tick by, the chance of heat returning to southern Australia slowly declines as autumn takes hold.
