From sweltering to soggy for southeast Australia

09:29 AEDT The pre-summer heatwave will come to an end across South Australia and most of Victoria this weekend, as the trough responsible for bringing in the heat is set to move across the region, bringing cooling showers and a southwesterly wind change.     The relief from this early season heat will certainly be a welcome change for SA on Saturday, with most of the state recording maximum temperatures more than 10 degrees above average on Friday.
