16:44 AEST The mild autumnal weather that southeastern Australia has been basking in this week is about to come to an abrupt and chilly end, with snow possible down to 600 metres in Tas. A strong cold front will cause the huge contrast in temperatures and is expected to sweep across southeastern Australia on Friday and into the weekend. The cold front will drag a frigid airmass over the region late this week, dropping temperatures to 3-5°C below average and bringing subzero overnight temperatures to some areas.
