The southern and eastern states are in for a warm week ahead as a series of troughs converge to filter heat from inland Australia. South Australia will be the first to turn up the heat, with the state's capital warming to a maximum temperature of 38 degrees on Sunday. Wednesday is shaping up to see the peak in temperatures, potentially reaching 39 degrees and contributing to an average maximum of 38 degrees for the four day period. Within a similar time frame, parts of Victoria and New South Wales will also be feeling the burn with Melbourne seeing four consecutive days over 30 degrees, the warmest of which being Wednesday at 36 degrees. Sydney is likely to be much more moderated by afternoon seabreezes, likely limited to just 31 degrees on Tuesday, however the western suburbs have the potential to rise to 37 degrees away from this cooling breeze. One of the more noteworthy aspects of this heat event is the widespread nature, with multiple capital cities enduring heat simultaneously, including Canberra which is forecast to see six consecutive days over thirty degrees, from Saturday until Thursday. It also goes without saying that this heat event poses a threat to livestock throughout rural areas, particularly inland. Conditions are expected to cool down from Thursday for South Australia and Victoria as a rain bearing front moves over the nation's south. However, parts of western Sydney will have to hold out another day, with relief due on Friday.
