If you're at work in Sydney this Monday, go have lunch in the sunshine. Or if you're at home, get the washing done ASAP. That bright yellow disc in the sky? It's called the sun and we're not going to be seeing too much of it this week after today.

Sydneysiders have just endured three straight days of more than 20 mm of rain – with 25.6 mm, 22.8 mm, and 21.6 mm recorded in the gauge at Observatory Hill on Saturday, Sunday, and Monday mornings respectively.

With the rain now having cleared, Monday is currently clear and beautifully autumnal across the city, with temps heading for the low twenties but feeling much cooler courtesy of a crisp southwesterly breeze.

Indeed, as we told you this morning, several cities including Sydney have just had their coldest morning of the year.

But the cool, clear weather in Sydney is set to change as the week progresses, with frequent showers and bursts of rain likely from Tuesday afternoon onwards.

"A near-stationary high pressure system over the southern Tasman Sea will maintain showery onshore winds along Australia's east coast this week,” Weatherzone meteorologist Ben Domensino explains.

"These showers will be enhanced by a deepening coastal trough as the week unfolds."

At this stage, there's the chance of falls of 50 to 100 mm across the metropolitan area by the end of the week.

In other capital cities:

• The rain could make it across the ranges and reach Canberra by midweek but it likely won't be as heavy.
• Brisbane should also cop its share of rain this week, though probably not as much as Sydney.
• Easterly systems like this generally leave Melbourne high and dry, and there is only a slight chance of rain for the rest of this week, with fine weather likely and top temps in the low-to-mid twenties on the cards.
• Adelaide, Hobart, and Perth should also stay mostly dry, with the mercury soaring into the high 30s in the WA capital later in the week.
• Darwin remains in wet season mode, with showers and storms possible every afternoon for the rest of the week.
