The season has broken - Adelaide gone from its warmest late autumn weather on record to its coolest, wettest week since winter, in just a few days.
In the five days to last Saturday the city averaged a maximum of 28.5 degrees, nine degrees above average and the warmest it has been this late in autumn in 136 years of records.
Since a cold front arrived on Saturday it has cooled down significantly. The city only reached 15.8 degrees on Monday, its coldest day since spring.
The cold front was strong enough and contained enough moisture for 14mm of rain to fall.
The colder, wet weather is sticking around for a while longer due to the presence of a slow-moving low pressure system south of the state.
The low should generate brisk winds and heavy showers on Tuesday and further cool winds and lighter showers on Wednesday and Thursday. There is potential for 15-to-25mm in the Adelaide area in these three days.
Gardens, parks and dams will all benefit after suffering for the last nine months.
By next weekend Adelaide should be half way to its monthly average rainfall of about 60mm.
Regarding the chill, the temperature should stay below 18 degrees until Sunday.
This is turning into Adelaide's coldest, wettest week since winter.
Residents can pack away their summer clothes. The warmth experienced last week will not return until at least spring.
