Forecast issued at 4:30 pm EDT on Saturday 10 October 2015.
A strong and slow-moving high over the Tasman Sea extends a ridge into northeastern New South Wales, and is directing generally warm and humid winds across the state. This airstream is feeding into a broad low pressure trough over the south and west, and will lead to unsettled weather in many districts during the next few days. Shower and storm activity is forecast to peak during the weekend as the next cold front moves in from the west and interacts with the warmer air ahead of it. This front should move to northeastern parts of the state during Monday, where it may linger for a day or two as a new high develops across the south.
