Large hailstones, wild winds and heavy rain are forecast for parts of Melbourne as a cool change rolls over the city.
After four days of heat, the Bureau of Meteorology say a storm is likely to hit Melbourne this afternoon.
Thunderstorms are due to hit Melbourne between 4pm and 6pm on Tuesday, bringing damaging rain, hail and wind, as well as a welcome 10C drop in the temperature which earlier reached 36C.
"If these storms do develop there is the potential that they could become severe ... we might see damaging winds in excess of 90km/h, heavy rainfall that could lead to flooding and also large hailstones as big as two centimetres," Bureau of Meteorology senior forecaster Stephen King said this morning.
While the heat appears to have stuck around at 3pm, the Bureau predict a 70 percent chance of rain for the city - likely to hit in the afternoon and evening.
