Australian Capital Territory Forecast

No warnings for the Australian Capital Territory

Forecast issued at 5:15 am EDT on Wednesday 19 December 2018.

Weather Situation

A weak high pressure system over the northern Tasman Sea extends a ridge to the north coast while a trough over central parts of Australia is moving east. This pattern is drawing hot air from central Australia into inland New South Wales, leading to heatwave conditions in some areas. The trough is expected to deepen later today it enters the far west of the state, then shift further east during Thursday before stalling and weakening about the northern slopes on Friday and Saturday. Shower and storm activity is expected to be generated by the trough over the next couple of days, though cooler conditions are expected in its wake. A high pressure system is forecast to drift across southeastern Australia during the weekend.

Forecast for the rest of Wednesday

Light winds becoming east to northeasterly 15 to 20 km/h in the evening then becoming light in the late evening. Daytime maximum temperatures 24 to 30.
