There have been some remarkably low temperatures recorded across Australia during the last week and more frosty starts are just around the corner.

A pulse of cold and dry air, combined with clear skies and light winds underneath a high pressure system, sent overnight temperatures plummeting across much of Australia late last week.

The coldest place in the country during the past seven days was in central western NSW, where the mercury dipped to -11.1 degrees at Marrangaroo on Sunday morning. It also cooled to -10.1 degrees at Armidale and Cooma Airport on the same morning, which was Armidale's this lowest temperature in eight years.

In the Blue Mountains, Lithgow's -9.3 degrees on Sunday was its lowest temperature in records dating back to 1965. Dubbo's -6.0 degrees on the same morning was its lowest minimum in 68 years.

Queensland's Oakey registered a low of -6.3 degrees on Sunday morning, which was its coldest morning since 2011 and the state's lowest temperature in four years.

Mount Hotham registered Victoria's lowest temperature so far this year, dropping to -7.5C on Sunday.

Since last weekend, increased wind a cloud cover associated with a flurry of cold fronts have helped lift minimum temperatures across much of the country. However, another big high will take up residence over Australia from Friday, once again unleashing widespread frost across the eastern half of the country this weekend.

Inland areas of SA, northern Victoria, NSW, the ACT and southern Queensland are likely to experience widespread frost on both Saturday and Sunday mornings.

While it will certainly be cold, temperatures aren't expected to reach as low as last weekend for most areas, due largely to the air not being as dry this time around.
