Another burst of wintry weather will cause showers, thunderstorms, blustery winds and low-level snow in southeastern Australia early next week.

A mass of polar air will spread across the nation's southeastern states on Sunday and Monday in the wake of a strong cold front.

Damaging winds are likely to develop in alpine areas from Sunday and could also occur in other areas of southeastern Australia.

Severe weather warnings could be issued in the coming days.

The impending air mass will be cold enough to cause low-level snow in some states and territories.

Snow could fall down to 600 metres in southern NSW on Monday.

However, the snow from this system won't be as heavy, widespread or long-lasting as it was last week.

Another front could clip southeastern Australia on Tuesday or Wednesday, maintaining chilly winds, showers and snow into the middle of next week.

After a warm top of 23 degrees on Sunday temperatures will return to a more wintry 19 degrees on Monday and Tuesday with an overnight low on just 8 degrees on Tuesday.
