Oberon bathed in spring sunshine on Monday as the town reached a top of 21 degrees.

But on Tuesday morning, the region woke to snow as a cool change and rain moved in from the south of the state.

Oberon is predicted to struggle only to 11 degrees on Tuesday.

Live Traffic issued an alpine condition alert for the Great Western Highway from Leura to Bathurst due to the freezing weather, saying traffic was affected in both directions.

Drivers were asked to reduce their speed and drive with caution.

After warm, dry days from Wednesday to Friday, Oberon is predicted to be wet from Saturday on.
