Steady rain and scattered thunderstorms have delivered a season's break to many areas as falls in the past two days top 40 millimetres.
After falls of between 5-10 millimetres in a band from Charlton in the north to Ballarat in the south and east to Romsey and Lancefield, Wednesday delivered a further 30mm and higher to many areas.
The heaviest falls to Wednesday morning were 11-15mm in the Central Highlands, near Trentham.
Further falls were recorded and scattered thunderstorms were active.
On Wednesday Bureau of Meteorology duty forecaster Rod Dickson said 5-10mm was the general number but there was potential for further rain from Wednesday through to Thursday night and into Friday morning.
Showers and storms should redevelop across the west and south before moving into the north-east where the heaviest falls were possible.
Mr Dickson said falls of 50-100mm were possible in the north-east with isolated heavier falls possible on the ranges.
Central parts of the state could receive 20-40mm, while falls of 5-15mm were possible over eastern parts of the Mallee and Wimmera.
The current falls come as the Bureau of Meteorology has stuck to its outlook that a short-lived El Nino was likely.
According to the latest ENSO Outlook released on Tuesday, if El Nino did develop in May, it was likely to be short-lived, with most models indicating that the ocean would likely cool through winter and spring.
It remains at El Nino Alert, meaning the chance of an El Nino developing in 2019 was about 70 per cent.
