A massive downpour has lashed the city with conditions looking more like July than December.
Heavy rain began falling in the city shortly after 11am, sending people scrambling to find umbrellas and jackets.
Earlier a fierce cold front put a quick end to a warm morning.
Strong winds, rain and storms struck Victoria as commuters were making their way to work.
The temperature dropped eight degrees in about two hours — from a pleasant 25C at 5.30am to just 18C at 7.30am.
About 3mm of rain has fallen in the city so far.
And it’s going to get even colder with parts of the state revisiting winter tomorrow.
Bureau of Meteorology severe weather meteorologist Steven McGibbony said yesterday a cold front with strong westerly winds would arrive early this morning.
“People are likely to need their brolleys as they head into work or school, but be careful, your brolley might turn inside out as there is quite a bit of wind on the way as well,” he said.
Gusts of 90 to 110km/h are expected, with rain also on the way.
“We’re looking at around about five to 15mm through most parts,” Mr McGibbony said.
“Possibly up to 20 to 30mm if we do see some storms.”
Strong wind warnings have been issued for Melbourne, Horsham, Warrnambool, Seymour, Maryborough, Ballarat and Geelong.
Mr McGibbony said Friday’s conditions were so cold we could see snowfall above 1200m.
“There’s quite some cold air behind this change,” he said.
“Temperatures are dropping to mid to high teens in the south.”
BOM issued a severe weather warning yesterday for the Central, South West, North Central, parts of East Gippsland, Northern Country, North East, West, South Gippsland and Wimmera districts.
Melbourne will drop to 19 degrees overnight, followed by a top of 24 degrees on Thursday.
More rain is expected on Friday with a low of 11 and top of just 17.
