Victorian's have been warned to prepare for a coming heatwave, this weekend, with little relief until early next week.
While it will be slightly cooler in southern Victoria on Friday, things will start to heat up by Sunday, according to Bureau of Meteology senior meteorologist Richard Russell.
"Temperatures do start to peak across northern Victoria, later in the weekend," Mr Russell said.
"On Sunday, we are looking at temperatures in most major centres of above 40 degrees, peaking at potentially 43 or 44 degrees along some of the border communities."
There'd be no relief until Monday, into Tuesday, Mr Russell said.
"Fire danger will be the main concern - while the winds are quite fresh, to strong, with the coming change, they don't look like being damaging."
The BoM said a high pressure system would remain over the Tasman Sea over the coming days.
A trough extending from inland Australia to central Victoria would move to the far northeast of the State, as another high develops south of the Bight.
This high will move eastwards and weaken, leaving a ridge across Bass Strait .
Heat will continue to build on Sunday ahead of another trough developing between a low south of the Bight and a tropical system over WA.
The trough is expected to reach southwest Victoria during Monday morning then move slowly eastwards across the state.
Mr Russell said high temperatures would continue into Monday, before a cool change crossed the state.
"Unfortunately the nights will be quite warm, especially Sunday night, into Monday morning."
