The Bureau of Meteorology is forecasting snow down to 800 metres in Western Victoria, as a cold front blows in from South Australia.

Duty forecaster Beren Bradshaw said top temperatures across much of the state would reach the mid teens on Monday and Tuesday.

"This front that is coming through later on Monday has a lot of cold air associated with it," she said.

"It will cross over Western Victoria tonight and remain in parts of state in early hours of Tuesday. By tomorrow morning conditions probably will have warmed up too much - we are forecasting 12 or so which is enough for it to start melting. The earlier the better if people want to see snow.

"We are also expecting small hailstones and showers in Western Victoria, but the hail is more likely near the coast than inland."

Ms Bradshaw said cold fronts bringing snow sometimes came through at this time of year.

"These are the last few before we really start getting into summer weather," she said.

"There will also be a sheep graziers warning issued later on Monday as we are expecting temperatures to fall significantly. We are forecasting southwesterly winds behind the cool change to freshen up overnight and into the early hours of tomorrow."
