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.
Forecast for the rest of Saturday
Showers and thunderstorms over most southern, central and western districts, chiefly on the tablelands. Fine and partly cloudy through the northeast. Northwest to northeasterly winds, turning southwesterly in the southwest late tonight.
Sunday 11 October
Showers and thunderstorms possible in most districts, more likely in the northeast. Northeast to northwesterly winds, freshening along the coast and in the far west. Winds turning west to southwesterly in the south.
Monday 12 October
The chance of showers or thunderstorms in the east. Fine in the west. Northerly winds in the northeast, tending southerly elsewhere.
Tuesday 13 October
A few showers and the chance of thunderstorms about the ranges and coast, mostly over the northern half. Fine and mostly sunny in the west. Southwest to southeasterly winds.
Wednesday 14 October
A few showers over the far northeast. Fine and partly cloudy elsewhere. North to northeasterly winds in the east, light winds remainder.
The next routine forecast will be issued at 4:30 am EDT Sunday.
