A deep trough is located offshore, while a firm ridge envelops southern WA. The ridge starts to shift east later Wednesday, allowing the trough to move inland across the west coast on Thursday ahead of a weak cold front brushing the south coast on Friday. A weak ridge will form in the southwest before another cold front approaches over the weekend.
