Weekly Weather Outlook

This week, I wanted to take a deeper dive into how we actually make weather forecasts, and what we mean when we talk about forecast models, confidence, and the chances of receiving certain types of rainfall or weather conditions in our seasonal and regular weather updates.

That’s what we’re focusing on in this week’s national forecast.

Alongside that, we look at a slow-moving low-pressure trough moving across the Australian continent, bringing some decent rainfall to parts of the country—particularly central and southern WA, as well as coastal areas across the southeast.

Meanwhile, much of the north remains dry and stable.

Have a great week, stay safe, and I’ll see you next time!
