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
locations generally fell to between 0 and 3 degrees, while coastal sites were
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.

Maximum temperatures today were generally 5 to 7 degrees below average. Most
locations recorded between 14 and 16 degrees. The highest maximum of 17 degrees
was shared by many sites including Mildura, Avalon, Shepparton and Wangaratta.

Melbourne's temperature ranged from an overnight minimum of 7.1 degrees at
7:54am to a maximum of 14.9 degrees at 3:12pm. In the 24 hours to 9am this
morning, 10mm was recorded in the city gauge, mainly associated with the

eastern suburbs and less in the west. Some very light falls were recorded in
some suburban sites this morning, however no rainfall was recorded in the city

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.
