At 4.30am on Friday, the bureau issued a severe weather warning for damaging winds for much of Victoria. Melbourne, Geelong and Seymour are set to feel the brunt of the blast.

The wild weather is being fuelled by an intense low pressure system south-west of Tasmania and an associated cold front over western Victoria that is expected to move east throughout the day.

By 9am, Melbourne is set to be thrust into thunderstorms, scattered in rain and potentially hit by hail, Bureau of Meteorology duty forecaster Beren Bradshaw said.

"The wind is ahead of the front forecast to come through later this morning, and we will see the winds ease as the change goes through - the wind will shift west to north westerly," she said.

"We're expecting rainfall between 10 and 15 millimetres in the Melbourne area that will start to come across in the next couple of hours.

"We're expecting the rain to continue into the evening, there's the possibility of seeing some hail and isolated thunderstorms."

The alpine region is expected to be hardest hit, with wind gusts up to 130 km/h predicted.

By 6.30am Friday, Melbourne had already exceeded its maximum temperature, hitting 17.5 degrees - briefly making the city one the warmest places in the country.

The showers will remain until at least Tuesday, and then pick up again on Wednesday.

"There's a possibility of hail still on Saturday and our first clear day is Tuesday, but the highest [rainfall] totals we will see are likely to be across today," Ms Bradshaw said.

The State Emergency Service received 55 calls for help in Victoria between 6pm Thursday and 7am Friday.

"It's been pretty quiet, the jobs were mostly in the mid-west and central for trees on the road," a SES spokeswoman said.
