However, strong winds are predicted. It is the beginning of the NSW school holidays and campers in Barrington Tops are being warned to take into account the wind chill factor.

The Bureau of Meteorology has issued a gale warning for our (Macquarie) coast and further south today Friday and Saturday and a sheep graziers alert is in place for the much of the State, including the Hunter and Mid North Coast.

Parts of NSW / the ACT will receive a wintery blast on Friday. This could impact travellers at the start of the school holidays.

The weather system could bring snow to low-lying areas of NSW and the ACT, damaging winds and the potential for thunderstorms with small hail.

The bureau says the cold front will bring a vigorous westerly change to southern and central parts of the New South Wales coast on Friday afternoon, continuing to the northern coast overnight. Behind this, a high pressure system is forecast to move across southeast Australia during Sunday and Monday, while a deep low develops over the southern Tasman Sea. This high looks set to be the dominant feature in the region until the next change mid-week.

After a predicted high of 28 degrees on Friday, temperatures are unlikely to exceed 20 degrees over the weekend.
