Rather cold and blustery at first with sub-Antarctic air at times and a few showers. Snow settling to 800m into the morning of the 3rd and to 600m into the morning of the 4th - very low levels for summer. Snow was heavier and more persistent about the exposed western and central mountains and snow remained on higher ground for days. A further dusting of snow to 1000m into the morning of the 7th. High pressure moved to the east on the 9th with a warm continental airflow then a cooler westerly stream to follow. The period 17th-30th was completely dry. Most of Australia experienced record heat during this time but Tasmania was cooler in a zonal westerly flow and cloudy. A warmer northerly wind on the 20th then a comprehensive cooler change pushing intense heat to northern parts of Australia. A new high built to Tasmania's south-west on the 23rd with a dry but very cool south-east wind. By the 25th high pressure was dominant to the east and northerly winds drew very hot air back across southern Australia. Tasmania's inland became hot and sunny but seabreezes kept Hobart comfortable. A freshening wind on the 30th saw very hot air spread to the coast. Cloud increased in the afternoon ahead of a front and there was a thundery shower in the evening. The 31st was dry.
