plains. Snow falls were reported about alpine peaks. In the 24 hours to 9am the
highest rainfall totals was 37mm at Mt Donna Buang.



The front brought a significant cold airmass over the State, which resulted in
overnight temperatures 5 to 10 degrees below the April average. Inland

slightly warmer, mostly recording between 5 and 7 degrees. For most Victorian
towns this was the coldest night of the year so far. The coldest location

and Ballarat recorded -2 degrees.



It was a cloudy day in the south today, with some isolated showers near the
coast. Skies were generally clear and sunny in the north. Rainfall totals in
the 7 hours to 4pm this afternoon were generally less than 1mm, however some
higher totals were recorded at elevated sites due to snow melt.

was shared by many sites including Mildura, Avalon, Shepparton and Wangaratta.

7:54am to a maximum of 14.9 degrees at 3:12pm. In the 24 hours to 9am this

Explanatory Notes
A weak ridge of high pressure extends over the State from South Australia. A
cold front crossing the Southern Ocean is forecast to reach the far southwest
late tonight before crossing the rest of the State on Thursday. A high pressure
system building over the Bight on Thursday will then extend a ridge towards NSW
on Friday and maintain a west to southwesterly airstream over Victoria into the
weekend with occasional embedded weak fronts affecting the south.
