Wild weather on the way for New South Wales

Craig McIntosh, Sunday June 25, 2017 - 12:42 AEST

After a month of mostly high pressure, a cold front and trough will bump away the high and bring some woolly weather later this week to parts of New South Wales.

A broad high pressure system is going to keep lingering over NSW on Monday and Tuesday, bringing cold nights and nice days to most areas. Come Wednesday and into Thursday, a trough to the north of the state looks to combine with a cold front to the south and together they will be unstable.

Unfortunately, the cold front does not appear to have a lot of precipitation with it, meaning snowfalls will be light. The trough to the north, however, will have enough tropical moisture in it to set off some heavy showers and embedded thunderstorms for parts of northern NSW. During Thursday, parts of the North West Slopes and Plains as well as the North Coast and adjacent inland could see upwards of 30-60mm of rain alongside thunderstorms. There is a risk of some storms being severe, exacerbated by an upper low pressure system.

By Friday, the system is likely to have moved away from the North Coast, out into the Tasman Sea. It's not all over though, as a southerly blast from the cold front looks to roar up the coast. This will likely bring dangerous conditions to most of the NSW coast.

By the weekend the system will be affecting New Zealand, and it's back to high pressure for NSW. Another cold front will sweep across southern NSW later on Sunday, and early indications are that it will have more moisture than its predecessors, bringing the possibility of snow.
