Almost all of New South Wales experienced a very cold morning today, with most recording their coolest morning so far this month and some dropping to nine degrees below average.
It was Tuggeranong's coolest October morning since 2001 dropping to -1.7 at 6:30am. Bathurst also had a cold morning, dropping to -1.6 degrees at 6am, its coldest October morning since 2004. Dubbo almost hit freezing this morning, recording 0.2 degrees and registering its coldest October morning since 2003. Along the coast, Moruya chilled to 2 degrees, its coolest morning since 2007.
Cowra, Parkes and Wagga Wagga also had their coolest morning since July, while parts of Sydney including Bankstown, Terrey Hills and Campbelltown recorded temperatures not seen since the end of winter.
These icy temperatures and light winds provided excellent conditions for frost formation, resulting in widespread frost across the state.
A stronger than usual cold front combined with a high pressure system rapidly building in its wake was the cause of these unseasonably cold temperatures.
Parts of the state will still experience a cool morning tomorrow, although generally not as cool as this morning. However, from today a low pressure trough will filter heat over the state from inland parts of the country. This will gradually bring minimum temperatures into the double digits for most places by Thursday.
