With much of southeastern Queensland still experiencing overnight minimum temperatures that are at least eight degrees below the long-term monthly average, it's likely that more cold fronts will extend this cold into the weekend.

Temperatures this morning were between eight and 10 degrees below the long-term monthly average, with places like Beaudesert, Dalby and Stanthorpe also cooling to well below zero degrees.

This comes as a lingering dry airmass in the wake of a series of frontal systems lingered over the eastern interior, and together with clear overnight skies inhibiting the trapping of heat, brought these extremely cold early mornings.

A series of cold fronts are expected to impact the southern and southeastern parts of the country from Wednesday, preventing any significant daytime heating. Although the bulk of rain and any snowfalls from these systems should generally be isolated to the southern parts of the country, affecting mainly South Australia, southern New South Wales, Victoria and Tasmania, the cold air associated with these systems will spread across the eastern interior.

On Friday and Saturday, early morning temperatures could be below freezing for most of the east as skies clear, including most of the interior west of the Great Dividing Range, slopes and plains and over the tablelands. Temperatures near freezing should also extend into parts of Sydney and southern Queensland early from Friday.

Warmer conditions are expected from Sunday as frontal activity decreases, and high pressure systems become the dominant feature over the eastern parts of the country.
