Summer snow a chance this weekend
It could snow in Tasmania this weekend and the mainland alps may see their first flurries of 2018.
A relatively strong cold front will sweep over Australia's southeast during Friday night and Saturday morning, followed by a second, weaker front on Saturday.
Cold air from the Southern Ocean will spread across Tasmania, Victoria and southern NSW behind the pair of fronts, dropping temperatures enough to produce highland snow.
The coldest air will arrive behind the second front, with the best chance of snow occurring late on Saturday in Tasmania's central highlands and early on Sunday morning in the mainland Alps.
Unfortunately, moisture will be limited when the coldest air mass arrives in the mountains, so the summer snowfalls will be limited to flurries, or at best a dusting.
While there won't be enough snow to ski on, the prospect of colder weather this weekend is sure to be a welcome change from the warm and muggy conditions across Australia's south east today.
Warm northerly winds combined with a stream of tropical moisture are making today's temperatures feel particularly sticky.
At 10 o'clock this morning, Melbourne's apparent temperature was 28 degrees due to calm winds and high relative humidity. After reaching the low thirties this afternoon, the city is forecast to top out at 21 degrees on Saturday and Sunday.
Hobart is forecast to have its coolest weekend in six weeks and will Saturday will struggle to reach 20 degrees thanks to cloud and showers.
Canberra's forecast top of 22C on Sunday will be the capital's coldest day so far this year and 15 degrees cooler than last weekend.
Interestingly, the moisture causing today's sweat and this weekend's snow is being drawn south from northern WA, where Tropical Cyclone Joyce made landfall on Friday morning.
