Showers eased overnight and only remained very isolated and patchy about the
coast. Patchy fog and extensive frost formed about the State during Sunday
morning. These cleared a couple of hours after sunrise. Sunny conditions
resulted in snow melts in rain gauges about the Alpine regions. Rain gauges
south of the ranges generally recorded falls of up to 7mm, though the highest
totals were 21mm at Mt St Leonard and 17.4mm at Mallacoota.

conditions prevailed. Winds were predominantly light. Some trace amounts of
rain were recorded across a handfull of locations about the State, with sunny
