Useful rainfall for south-west Victorian dairy farmers

The system, just south-west of Mt Gambier, SA, extended a trough over central Victoria.

The low will continue moving south-east over Tasmania on Friday, combining with a high over South Australia to direct west to south-westerly winds over Victoria.

Bureau of Meteorology senior forecaster Tom Delamotte said the highest falls were recorded in the north-east ranges, with 67.8millimetres at Archerton and 64mm at Mount Buffalo chalet.

"We also got 55.6mm at Warrnambool, which was the highest fall throughout the south-west," Mr Delamotte said.

Crossley, Vic, dairy farmer, Karinjeet-Singh Mahil wrote on social media the area had received "a small drop of rain last night".

"Brian (Schuler) got the cows across at 2.00am before the water got too high," Ms Singh-Mahil said.

"If he'd waited until regular morning milking time, there's no way the cows could have crossed.

"They got through the road underpass with water up to their bellies but by the time the kids and I passed through on the way to school, the underpass was full to the top."

Mr Delamotte said throughout the south-west, falls ranged between 15-30mm.

"We are going to see some further showers, push across Victoria, as that low pressure system gradually makes its way, through Bass Strait."

That would mean more falls for the south-west and about the north-east ranges.

"We do see a fairly good easing of the conditions, as we move into Friday, it will be a showery start for the day for southern and mountain areas, which will ease as we move into the evening," Mr Delamotte said.

"As we go into the weekend, we will see the weather system dominated by a ridge of high pressure it will be warmer in the north, back up to the mid 20's by the weekend."

The high is expected to weaken on Sunday, as another one strengthens, just east of NSW.
