In the past seven days, Nhill received 34.2 millimetres of rain, most of which fell on Thursday.

Longerenong received 30.4mm, Dimboola received 29.4mm and Horsham received 26mm.

Visitors flocked to the Grampians at the weekend as snow blanketed the national park.

The mercury at Mt William dropped to -2.5 degrees on both Saturday and Sunday mornings.

Bureau of Meteorology senior meteorologist Dean Stewart said the snow level was down to about 400 metres in parts of western Victoria on Sunday morning.

However, he said the snow wouldn't stick around for long in the Grampians.

"There might still be some snow at the very top of Mt William hanging around for a bit, but besides that there will be no further snowfalls for a while," he said.

Mr Stewart said the cold snap was coming to an end, with temperatures expected to return to average levels by the middle of the week.
