Melbourne is likely to have its warmest day this late in the season in eight years on Saturday, before rain and cooler temperatures arrive.
The city will reach a top of 25 degrees on Saturday thanks to warm and gusty north to northwesterly winds. The mostly sunny skies will also invite many people to enjoy some late season warmth before autumn takes hold into next week.
A cold front will arrive during Saturday night leading to a mild Sunday with a few showers easing during the day.
On Monday a low pressure trough will cause patchy cloud to become widespread during the day with areas of rain developing. It will be a cool day with the temperature generally sticking below 18 degrees. Tuesday and Wednesday will then remain fairly cool in a run of days below 20 degrees.
A cold front should arrive late on Wednesday leading to a cold day on Thursday with a top of only 16 degrees expected, one below the May average. By Thursday, the warm temperatures of Saturday will be all but a faint memory. The temperature will struggle to reach into the mid twenties again before spring as the airmass cools over the nation.
