This follows last Sunday morning's drenching when flash flooding occured in parts of the city.

Yesterday the air was muggy, with temperatures between 16C and 20C.

Last night Ballarat was warned to prepare for damaging winds, flash flooding and large hailstones, with emergency crews remaining on standby.

Yesterday afternoon, Bureau of Meteorology weather radars showed large thunderstorms in the Bendigo to Macedon region.

The bureau said severe thunderstorms were possible in the area surrounding Ballarat last night.

State Emergency Service Mid West regional officer John Hooper said the Ballarat crew had no call-outs yesterday, which had been unexpected.

There had been one assistance call to help at Woomelang, south-west of Swan Hill, which was hit by a mini tornado yesterday, but the Ballarat unit was not required.

There was a crew on standby last night for call-outs, with heavy rain coming from Adelaide.

"It's been predominantly coming from the north and the weather is tracking it slightly to the east," Mr Hooper told The Courier yesterday.

"But we're certainly alert for it."

Since Saturday, 79mm of rain has fallen in Ballarat to 9am yesterday morning.

Sturt St vintage store Dear Prudence, which was badly damaged by Sunday's flash-flooding, was hopeful they would not be hit a second time by wet weather.

Owner Kelly Davies said yesterday the store's carpets had to be ripped up after extensive water damage.

She said she had only been in the premises for three weeks and estimated her damage bill would run into the thousands.

According to the bureau, an upper level trough over north-western Victoria was crossing the state last night, while a low-pressure system will move towards the region late today.

The bureau forecasted scattered showers for Ballarat today, with more muggy temperatures in the high 20s.

Another trough will reach western Victoria this afternoon, bringing rain in its path tonight, before clearing to the east early tomorrow.
