Canberra and Richmond were among a host of places to have their coldest morning since September, with more locations likely to join tomorrow.
The mercury plummeted across New South Wales last night as clear skies and mostly light winds allowing the surface to cool significantly.
Canberra fell to minus 4.3 degrees this morning, its coldest morning since the second day of spring. Thick fog shrouded parts of the nation's capital until after 8am.
Parts of western Sydney also had their coldest morning since September, with Richmond falling to 1.8 degrees as winds became light.
Locations with their coldest mornings since September stretched from southern Queensland to Bourke to Albury to Cooma. The Mid North Coast town of Kempsey was part of that list and also had its coldest May morning since 2006, dropping to one degree just before sunrise.
The Snowy Mountains have remained cold for almost a week now with Thredbo remaining below zero degrees since Monday night. Snow depths are at their highest for this time of year since 2009, recording 25cm at Spencers Creek on Thursday.
Tomorrow morning will be cold again for most of New South Wales as winds become light under a broad high pressure system. Nights will become warmer as cloud increases with an approaching trough on Tuesday, but day time temperatures will be cooler with the arrival of rain into Wednesday.
