A cold sequence of nights are set to return to large parts of eastern and southern Australia as a large high continues to drift east and strengthen on the approach to the southeast inland.

This is going to lead to a number of cold nights, with areas of light frost and thick areas of fog with high pressure trapping low level moisture in onshore winds over the southeast.

Fog Risk - Monday Morning - Valid Sunday 27th of June 2021.

Areas of fog could be heavy at times through central and northern Victoria and in pockets throughout southern and central inland NSW west of the divide Visibility could be down to less than 50m in some locations, especially at elevation and may take a good portion of the day to clear through some locations, so daily maximums may struggle to get out of single figures.

Frost Risk - Monday Morning - Valid Sunday 27th of June 2021.

Where the fog does not form, frost is likely to develop, but severe frosts unlikely with a little too much moisture and breeze about Sunday night. Conditions where it is clearer with the frost risk will warm up to near seasonal conditions.

The frost risk will continue through to mid week, but overall this week is looking fairly seasonal with the Indian Ocean Dipole playing a part of suppressing the colder drier airmasses from rolling through southern Australia, which we saw through April and May which brought those record breaking minima in many states.

Make sure you check out the forums and get talking. This is the much more pleasant way of interacting behind the firewall where social media turns a little crazy at times and your questions can go unanswered.
