Weather Situation
A west coast trough has developed, pushing south to southeasterly winds up the coast until it moves inland today. A high sits in the Bight, bringing northeasterly flow to the southeast coast before a cold front is expected to pass the south coast on Friday, leaving southerly winds in its wake, tending southeasterly as a ridge extends over the southwest during the weekend.
