Overnight temperature records tumble in Vic, Tas
Tasmania's wintry outbreak of the past few days collapsed rapidly yesterday, with high pressure, light winds and clear skies covering the island and Victoria by yesterday afternoon. As a result, temperatures dropped to record or near record October levels in parts of Tasmania, and some isolated pockets in Victoria (see panel below). Widespread frosts were reported, damaging grape, hops and vegetable crops in southern Tasmania. West of Melbourne, Laverton Airport broke its October minimum temperature record for the second time in 6 days, unusual given the 57 years of recording at the site. Melbourne City's minimum of 4.8 is the lowest so late in the year since 1984, while Hobart City's 1.8 is its lowest October temperature since 1983, and the lowest this late in spring since 1944.
