A strong cold front is expected to sweep across NSW this afternoon after a relatively mild couple of days in Newcastle.
The Bureau of Meteorology have forecast northwesterly winds which are set to increase ahead of the front, before leaving a cold and gusty westerly in its wake.
Meteorologist Christopher Webb from the Williamtown Weather Office, says temperatures are expected to reach a maximum of 20 degrees today, before the cooler conditions hit.
"Much colder conditions to come for tomorrow, Thursday and Friday and also the winds will strengthen this afternoon ahead of that front and may reach gale force this evening and overnight and the front goes through."
