The last time Ballarat received more than 100mm was in December 2004, with 107mm.

And September, 1996, was the last time Ballarat topped more than 113mm, with 129.6mm of rain.

From 10pm on Friday night to 5pm yesterday, 28mm of rain fell in the Ballarat.

It helped bring this month's total to 113mm, more than double the average of 55.3mm.

The mid-west unit of the State Emergency Service unit was kept busy in Ballarat, with six call-outs for storm damage and a tree down.

There was minor damage at Nazareth House, with the wild weather dislodging tiles from the roof.

Regional duty officer Tony Grimme said 20 SES volunteers attended call-outs during the weekend, with a crew sent to Horsham with light towers after a haystack fire.

``The public seems to be taking notice of the storm warnings and securing loose objects around their homes, which is a pleasing part of it,'' Mr Grimme said.

Stawell also had calls for help after 30mm of rain was dumped on the town at the weekend.

The Bureau of Meteorology is expecting isolated showers in Ballarat again today.

Summer will begin tomorrow, with a sunny day forecasted and temperatures in the low 20s.

Wednesday is also predicted to be sunny, with similar temperatures.

According to the bureau, a low pressure complex over south-eastern Australia had moved into the Tasman Sea yesterday, with a high pressure system approaching Victoria from the west.

A cold front will cross Western Victoria on Thursday morning, bringing showers from midday.

More showers are forecasted for Friday into the weekend.

Meanwhile, the bureau's seasonal rainfall and temperature outlook released last week revealed no swing towards a wetter or drier than normal summer.

But it has predicted cooler than normal nights in parts of Victoria from December to February.
