The Bureau of Meteorology says there's the potential for soaking rains, over much of Gippsland, early next week.
BoM senior meteorologist Tom Delamotte said a low-pressure system, approaching Victoria from the west, was bringing showers and thunderstorms to the state on Friday and into the weekend.
"On Saturday, we will see fairly showery conditions, some isolated storms around and the system could produce some small hail," Mr Delamotte said.
The bureau was predicting falls of up to 25 millimetres, in some areas.
But Mr Delamotte said once the system passed into Gippsland, there was potential for higher falls.

"Over the weekend, that system does move over the Tasman Sea, and it does look like it will develop into a fairly significant low-pressure system, off the NSW coast," he said.
'With that low developing, we will see increased south-west winds across Victoria
"That's going to drive some fairly persistent rain into parts of Gippsland on Monday and Tuesday and even continuing into Wednesday."
Falls of around 40mm were predicted, on Monday and Tuesday, tapering off in the middle of the week.
"By the end of those three days, we are looking at potential falls of up to 100mm."
He said the rainfall totals would depend on how far south the low-pressure system went.
"If it forms over northern parts of the Tasman Sea, we are not likely to see nearly as much rainfall over Victoria," he said.
"The further south it does form, we could see some potentially higher falls than the 100mm, over the three days."
Mr Dellamotte said rainfall, from the showers and thunderstorms, would be hit and miss, but the north of Victoria could expect up to 10mm.
On Saturday, central and eastern Victoria could see falls of between five-15mm, while in the west they were likely to be limited to five mm.
"On both days, there is potential for higher falls, from thunderstorms.''
