Winter's official arrival may still be a month off but it won't feel so far away today with rain, hail and snow set to fall on Victoria.

Any remnants of autumn's sunshine are likely to be gone from most Melburnians' minds with a forecast top temperature of only 15 degrees for the second day running after an overnight low of 8.4 degrees.

Bureau of Meteorology duty forecaster Rod Dickson said the city's eastern suburbs would bear the brunt of rain and possible hail throughout the day and evening.

Showers will be more scattered in the north and west of the city, Mr Dickson said.

The cool start to May has seen snow fall in alpine regions, particularly Mt Baw Baw but Mr Dickson said popular resorts in Mount Buller, Falls Creek and Mount Hotham may miss out.

The rain is expected to drench the eastern suburbs until tomorrow afternoon when the showers are predicted to ease.

Despite the wet weather, autumn's chilly goodbye may not herald a nasty winter.

Mr Dickson said the three-month outlook had predicted an increased chance of this winter being drier and warmer than average.

"[Today] is a bit of an early taste of winter but that is the longer forecast," Mr Dickson said.
