Weather Situation
A trough of low pressure lingers about the east, before weakening later today, as a slow moving high pressure system in the Tasman Sea will re-establish a ridge across southern parts. A trough is then forecast to briefly move into the west on Thursday, before another trough and cold front move more broadly across SA on Friday and Saturday.
