IDV10300 Australian Government Bureau of Meteorology Victoria Notes on the Weather Issued at 4:31 pm EST on Wednesday 29 July 2015. Recent Events Isolated showers and drizzle affected southern and mountain areas in the 24 hours to 9am. Most rainfall totals were 2mm or less. The highest rainfall totals were 13mm at Mount Sunday, followed by 10mm at High Ridge and Mount Useful. Minimum temperatures were generally within 3 degrees of the July average, although they were up to 5 degrees below in parts of the north and east where clear skies and light winds prevailed overnight. Most minima ranging between -1 and 7 degrees. The lowest overnight temperature was minus 5 degrees recorded at Mount Hotham, whilst in contrast the highest overnight temperature was 9 degrees recorded at Gabo Island and Wilsons Promontory. Areas of fog and low cloud across the north gradually dissipated, although some regions saw low cloud persisting into the early afternoon. Morning frosts were also observed in parts of the north and east. Areas of high and mid level cloud drifted in from the west during the day, however no rainfall was recorded from it up to 3pm today. Winds were mainly light to moderate north to northwesterly, although southeasterlies developed about parts of the Gippsland coast during the afternoon. Maximum temperatures were mainly up to 3 degrees below the monthly average, mostly ranging between 10 and 14 degrees. In the east temperatures were close to normal. The highest temperature was 15 degrees recorded at Bairnsdale and Point Hicks. In contrast, the lowest daytime temperature was minus 1 degree recorded at Mount Buller and Mount Hotham.

Explanatory Notes A large high pressure system centred near the northern New South Wales coast will move over the Tasman Sea Thursday. A cold front south of the Bight will move into western Victoria Thursday afternoon and will clear eastern districts early Friday causing cool northerly wind to shift colder westerly and showers to extend from the west with highland snowfalls. An active long wave trough will remain in eastern Australian longitudes through the forecast period with further fronts crossing Victoria early Saturday, later Sunday, a stronger front on Monday and another early Wednesday. These fronts will periodically reintroduce showers, colder westerly or southwesterly winds and highland snowfalls, with milder conditions in between. A northwest cloud band may link with Sunday's system bringing some rain to parts of the north - however the extent of this connection is unclear at this stage. The strongest front in the sequence is Monday's which could give local hail and thunder in the south and lowland snowfalls.
