Volunteers were called to the aid of travellers who had found themselves in trouble when between 10-15 centimetres of snow fell on parts of Orange.

While more snow is forecast, the reported snowfall on Saturday was short of the 20-centimetres which fell over one weekend in July, 2015.

NSW SES Public Affairs Officer Ilana Pender-Rose said the SES had asked Orange residents to avoid driving if possible.

"If you do need to travel around Orange or the Blue Mountains drive safely and watch out for black ice," she said. "And if you do need help - give us a call."

More snow was expected outside of the Alpine regions on Sunday with snow falling as low as 600-metres across some parts of the state.

"Conditions are expected to ease in Orange tomorrow but it will still be quite wild and windy," Ms Pender-Rose said.

"Be aware and take care driving until tomorrow night, possible even Monday morning."

Another cold front was expected overnight on Saturday with winds remaining gusty across the region.

The Bureau of Meteorology's Jane Golding said mornings in Orange were likely to "remain pretty cold" well into next week.

Sunday was looking at a low of -1°Celsius in Orange at about 6.30am with a maximum of just 2°Celsius during the day.

Ms Golding said more snow was predicted for Sunday, with downpours lifting by the evening.

Monday was forecast for a low of -1°Celsius in the early morning with a maximum of 8°Celsius during the day.
