Enjoy the last few hours of the sunny, winter weather while it lasts.
A cool change is forecast to hit Victoria this afternoon, causing the temperature to plunge as much as six degrees with showers across Melbourne's suburbs.
Bureau of Meteorology forecaster Dean Stewart said the cooler conditions were expected to sweep in between 2pm and 4pm today, and would be accompanied by winds of up to 55 kilometres an hour.
As the front passed through the wind would swing around from the north to a cooler south-westerly, bringing to an end a string of pleasant winter days that have broken through the 20-degree barrier.
"A few showers will push across as the front goes through," Mr Stewart said.
"Some suburbs might end up with a couple of millimetres, but that will be about it, no real heavy rains or anything.
"The temperature will drop from around 21 degrees down to somewhere around 15 degrees, perhaps even a little bit cooler an hour or so later."
The mercury is expected to reach a maximum of 17 degrees in Melbourne tomorrow and over the weekend, with partly cloudy conditions.
That is still warmer than the average maximum August temperature in Melbourne of 14.9 degrees.
A further cold front would sweep in on Sunday night, Mr Stewart said
"It looks like that will produce some isolated showers once again and probably a period of west to south westerly winds in behind that, there will be a couple of showers around."
