There will be a sharp drop in temperatures on Thursday, with snow expected in mountainous regions and scattered rainfall along coastal areas, according to the Department of Meteorology.
Temperatures will reach approximately 12 degrees Celsius in coastal and inland areas, dropping to zero degrees in higher mountain regions where frost is expected to form.
Strong northerly winds of 4 to 5 Beaufort are forecast, with rough seas expected particularly in western and northern coastal areas, moderating in southern and eastern regions by afternoon.
Evening conditions will deteriorate with increased cloud coverage and potential isolated rainfall in coastal areas, whilst snow is expected to continue in higher mountain regions and some lower areas.
The cold weather system will persist through Friday, with temperatures remaining significantly below seasonal averages. Scattered showers and snow in mountainous regions are forecast to continue.
The meteorological service predicts a slight improvement for Saturday with generally clear skies and occasional localised cloud coverage, before conditions deteriorate again on Sunday with partial cloud coverage and isolated rainfall.
