It is a little hard to understand, yet cold air from the south pole has pushed hot air from the north, down to the south of Australia. My town usually gets to 45C in summer, yet today it is 47C and may get to 48C. And night time it only drops to 38C. https://youtu.be/9ZMxyEg-zvk?si=QxtNw-qZt-2x03Ic
