With the pattern starting to shift back to an easterly flow across the southeast and east of the nation, the risk of frost ends for the northern and central inland of NSW and much of QLD, with more cloud, unsettled weather moving in plus higher humidity values sweeping in via the easterly flow.
The high-pressure centre being closer to the southeast inland of the nation will support a calm and clear sky, and with the colder air through the middle and upper levels of the atmosphere, frost will likely form for many areas during Wednesday morning.
Severe frosts are likely for many through southern NSW and into much of inland Victoria.
Similar conditions are forecast for Thursday morning.
More coming up in the evening updates from 5pm EST.
