  • For those who are not familiar with the difference between an ex-tropical cyclone / tropical low and an east coast or polar low, the temperatures in the mid-levels are relatively warm. The map here shows temperatures in northern NSW fairly warm 0 to -2C compared to the approaching polar low (upper trough extension of the low) with temperatures of -14C and obviously colder approaching Victoria. For the position of the low, just refer to the wind barbs circulating the centre of the low in each case!
