A complex low pressure system helped to deliver thick cloud cover and significant rainfall on Friday. The rain and cloud blocked out the sun, creating a cooling effect and causing some locations to have their coldest day in a while.

Some of the highest rainfall totals during the 24 hours since 9am on Friday came from the Illawarra and Shoalhaven regions in NSW. Foxground, Broughton Creek, Port Kembla Brogers Creek all recorded totals above 100mm, with a site in Nowra having 204mm of rain. Many surrounding places fell just shy of the 100mm mark.

Adelaide's West Terrace site experienced a maximum of only 10.3 degrees, with gusty southeasterly winds making it feel more than a couple of degrees colder at times. The cold extended its reaches beyond Adelaide, with snow even reaching the Flinders ranges.

The mercury only reached a cold 13.6 degrees at Observatory Hill in Sydney, meaning that this was its coldest day since June 2016 and its coldest August day since 2013. It was a similar story for the surrounding areas, with a large swathe of the Sydney basin reaching over 4 degrees below the average for this time of year.

The nation's capital shivered through a day where the maximum only reached 7.8 degrees at Canberra Airport, its coldest day since July 2016 and coldest August day since 2015.

Over the next couple of days, it looks unlikely that we would see temperatures as cold as Friday in most places. The cooling effects of the cloud cover and showers should remain although the airmass should be too warm to challenge the chilling maximums of Friday.
