A high pressure system near New Zealand extends a ridge to the New South Wales north coast, while a trough extends through central parts of the state. A very warm airmass will linger over central and northern districts until a cold front arrives on Tuesday. This front is forecast to bring cooler conditions, but any unsettled weather should be restricted to areas east of the Divide. Meanwhile, Tropical Cyclone Tatiana over the Coral Sea is forecast to track southwards during the next day or two, possibly bringing large swells onto the northern New South Wales coast at the start of the week.
