Bureau of Meteorology forecaster Jessica Lingard said conditions are set to ease later today.
"Across the rest of today we are expecting some more showers and thunderstorms to continue, they will be on an easing trend though, especially as we move through into this afternoon and this evening," Ms Lingard said.
Ms Lingard said plenty of rain is forecast for the long weekend as well.
"It does look like a very wet Saturday and Sunday around the metro area and if you are heading away on holiday for the long weekend, perhaps take a glance at the forecast for wherever you're heading and make some wet weather contingency plans."
