The Bureau of Meteorology said the low pressure trough lying near the northern New South Wales coast is decaying as a high pressure system over the southern Tasman Sea becomes more established.
“A cold front is expected to move into the west of the state later today and continue through Wednesday.
“This will be followed closely by another, more significant, cold front during Thursday.
“Later on Thursday and during Friday a low pressure system is forecast to form and deepen over the Tasman Sea in response to the second front.”
This second wave will bring vigorous south to south-westerly winds and large waves.
Over the weekend Lismore temperatures will range between 7C and 19C during the day.
Minimums will be slightly warmer on the coast with 9C for Ballina and 13C for Byron Bay.
