Wednesday morning was the coldest morning since October 30 2017 with a minimum temperature of 9.4 Degrees Celsius recorded at Perth Metro.This occurred due to boundary layer decoupling leading to excellent radiational cooling and cold air pooling near the ground of already cool air.

Warmer weather from Thursday with slight warm air advection. 

Then high pressure system likely lies to the south during the weekend leading to a somewhat east-southeasterly pressure gradient.
