In the coming week, a series of troughs and strong cold fronts are expected to move across the south of the country, significantly increasing winds, bringing about rainfall, and potentially causing the first autumn snowfalls in Tasmania. 

The end of the weekend and the beginning of the week is anticipated to be warm, windy, and stormy in the southeast of the country as a trough, followed by fronts, move across the region. However, by Tuesday, things will become windier and colder as an area of low pressure intensifies south-southeast of Tasmania. Several troughs and cold fronts associated with this broad area of low pressure will sweep across southeast South Australia, Victoria, Tasmania, and southern New South Wales during this period, leading to a significant drop in temperatures across the south, along with a burst of strong, possibly damaging wind gusts exceeding 90km/h (particularly in exposed coastal areas and elevated regions). 

Tasmania is expected to experience the brunt of the weather, with temperatures dropping to the mid-teens on Tuesday and struggling to reach 15°C on Wednesday. On the other hand, Adelaide, Melbourne, and Canberra are likely to experience temperatures ranging from the high teens to low 20s. 

The airmass will be cold enough to generate the first snowfall of March 2023 in Tasmania, with snow anticipated to fall as low as approximately 700-800m, mainly on Tuesday and Wednesday, with a possibility of some flurries during the early hours of Thursday. 

Following this, a high-pressure system will move over the southeast from Thursday, resulting in reduced winds and settled weather for the remainder of the week.
