7 day weather forecast

 Effective as of 4:00 PM Saturday May 8 2021

Explanatory notes:

With the subtropical high pressure ridge slightly to the south, fine conditions.

Progressively warmer afternoons until Tuesday with warm air advection as the high moves into the Great Australian Bight.

A cold front likely moves over the region from the south on Wednesday bringing a colder air mass over the region with a strong high pressure system, building to the southwest leading to breezy east-southeasterly winds thereafter. Still some uncertainty on the details this far out.
