A wintry November blast not felt in Melbourne since 2007 will dump isolated rain and hail on Friday - and it plans to stick around for Stakes Day at Flemington racecourse.

The Bureau of Meteorology expects a series of cold fronts to keep temperatures well below the 22-degree November average until Monday.

The first front arrived on Wednesday, dampening Thursday's Oaks Day fun at Flemington and dumping good rain through South Gippsland, including 29 millimetres at Warragul.

Areas in Melbourne's outer east received up to 20 milllimetres and central suburbs up to five millimetres.
