Forecast issued at 4:05 am EDT on Wednesday 26 November 2014.

Weather Situation

A weak high pressure ridge has developed over the southern and central coast. A southeasterly change is expected overnight tonight in the Sydney area. A high pressure system will move into the central Tasman Sea Friday with rather fresh southeast winds on the north coast but lighter winds over remaining waters until afternoon sea breezes develop. The high is expected to move east over the Tasman on the weekend as a slow moving trough deepens near the NSW/SA border, resulting in freshening northeasterlies along the NSW coast.
