According to the latest information from the Bureau of Meteorology, Mount Canobolas and other higher-altitude areas to Orange's west and south-west are predicted to be white come the end of the week.

Other parts of the Central West near Bathurst, Lithgow and Oberon have also been included in the updated forecast.

According to www.weatherzone.com.au's Ben Domensino, a pair of cold fronts will cross southeastern Australia between Tuesday and Saturday, each bringing a burst of showers, storms, chilly wind and snow.

The first, weaker front will cross South Australia, Victoria, Tasmania and southern NSW on Tuesday and Wednesday.

This system will bring about 15 millimetres of rain to some areas, with the heaviest falls occurring along exposed coastal areas and about the ranges.

The air behind this front will be cold enough for a few centimetres of snow on the mainland alps during Wednesday.

The second front will be much stronger and will spread a large pool of cold air across southeastern Australia between Thursday and Saturday.

This front and the cold air in its wake will produce a wintry mix of showers, blustery winds, storms, small hail and snow in multiple states.

Drier and calmer weather will return to most of southeastern Australia on the weekend as the front moves out into the Tasman Sea.

Snow at this time of year usually melts quickly because the underlying ground is still relatively warm. Snow usually starts to accumulate more steadily in the alps from June.
