Temperatures in the 20s across most of the state are expected until Sunday will bring an unusually warm end to May.
The Bureau of Meteorology says today's weak rain band will clear rapidly.
Monday's highest rainfall totals of 9 millimetres were recorded in the south-west of Victoria.
As the rain contracts eastwards, up to 5mm is expected on the northern slopes but little is expected elsewhere.
Other than a shower or two on Friday, the mild, dry weather will persist until a low-pressure system brings cooler conditions with the Bureau of Meteorology predicting falls of less than 5mm on Sunday.
The forecast run of eight consecutive days of 20 degrees or more in Melbourne has only been recorded five times before, most recently in 2014.
