Winter's icy grip will loosen in parts of south-eastern Australia today, with several areas headed for their warmest day of winter 2021 to date.
Canberra is heading for a top of 19C, with temperatures set to warm up throughout the day before showers move across the city later in this afternoon.
Canberra's highest temp to date this winter was 17.4C back on June 2, when autumn hadn't really given up.
The city's average maximums this winter have been 12.9C in June, 11.9C in July, and 13.5C so far this August.
Meanwhile the warm temps will extend all the way down the NSW south coast and across the Victorian border.
Merimbula, on the far south coast of NSW, is expecting 23C, its warmest this winter by a couple of degrees and a nice improvement on the average August maximum of 17.3C.
The warm temps will even extend to East Gippsland over the border in Victoria, with 22C or 23C forecast in some centres.
Although other parts of Victoria will miss the warmth, including Melbourne, which has a predicted top of 17C with showers moving in.
Sydney should reach around 25C in all suburbs. The city's highest reading to date this winter at the city's "official" weather station at Observatory Hill, beside the Harbour Bridge, was 25.6C on August 1, which could conceivably be exceeded.
The warm change is being triggered by air from the interior of the country being dragged south and east ahead of a cold front.
The front will drop temps by several degrees when it arrives late on Wednesday night or in the early hours of Thursday.
This front does not look like particularly good news for the snowfields.
The Victorian ski resorts are open again, and the NSW ski fields remain open to visitors from regional NSW and the ACT.
A strong wind warning has been issued for the Torres Strait and Peninsula Coast in Queensland with isolated showers southeast and northeast.
In WA, a much colder, wetter day is forecast with showers, cool-to-cold in the southwest, clearing shower and cool conditions in the south. Windy, cool-to-mild in the northwest. Mostly sunny, very warm in the northeast.
The Northern Territory will be mostly sunny, very warm in the north and interior with sunny and mild conditions in the south.
A windy day is forecast for Tasmania with coast wind warnings in place for the southwest with rain and cold temperatures in the south and north of the state.
