Sydney is set to shiver through its coldest day so far this year, with the cold snap also forecast to bring a generous dusting of snow to the NSW ski resorts.

The city is forecast to reach a top of 14 degrees on Sunday, as is Penrith and Liverpool, but Weatherzone forecaster Kim Westcott said it would feel even colder thanks to the wind.

"Even though it's mostly sunny, we've got a big pool of cold air from several cold fronts passing over Victoria and southern NSW," she said.

"The winds will be quite dry at times so it will actually feel a lot colder as well."
