Weatherzone meteorologist Guy Dixon said a strong front was forecast to move across the east coast of Australia from Tuesday.
“Early in the week we can expect the temperatures to really start to drop,” he said.
“Tomorrow we might see one or two centimetres of snow, or at least a light dusting, but that will only hang around briefly because the temperature will be around six or seven degrees [in the day], which is not overly cold.
“Any snow should melt straight away, particularly as the ground will be wet.”
Mr Dixon said Orange temperatures would drop to an average of one degree at night over the next five days, while daytime temperatures would reach a top of 11 degrees on Monday before dropping to seven degrees on Tuesday and Wednesday.
Mr Dixon said the average temperature for June was 10.5 degrees.
“This month Orange looks like having close to average temperatures for the month, if not slightly above,” he said.
The average rainfall for June is 72 millimetres.
