Rain steadily spattered down into southeastern South Australia between Thursday and Friday. Eventually, the slow-building rainfall totals were some of the highest seen in years for some locations.

A low pressure system perched over southeast SA on Thursday along with a trough and cold front helped to begin the procession of rain, but another low brewing closely behind extended the rain overnight to Friday.

In the 24 hours to 9am, Adelaide recorded 46mm of rain, its wettest day in four and a half years. Around 30-40mm of rain fell in and around the suburbs of Adelaide and on the Mount Lofty ranges, and rainfall extended as far north as the Pastorals but became much less significant this far north.

Hindmarsh Island was the other place which had significant rainfall, its 43.6mm being the wettest 24 hour total for 10 years.

The cold air behind this system is triggering chilly overnight temperatures with the clear skies under building high pressure. Adelaide dropped to just 6.8 degrees on Saturday morning, only the 5th time the minimum temperature has dropped below the long term average this month. This isn't too bad considering at this point last year Adelaide had just been through 8 consecutive mornings where the mercury dropped below 5 degrees.

The next couple of mornings aren't looking warm either, with a forecast minimum of 7 degrees for Sunday and Monday. However, the high pressure does mean there should be some nice, sunny days on the way. As cloud starts to build from another low pressure system, you might be able to shed the extra covers from Wednesday during the night, but keep an umbrella and jacket handy during the day.
