Weather News - Dribs and drabs for NSW

Thomas Hough, 18 July 2018

After another week of little to no rainfall, inland parts of NSW could see rain moving in at the end of the week.

Although a large proportion of the state is affected by the current dry spell, the most significant deficiencies are in the far west and northwest.

As of June this year substantial areas of Upper and Lower Western were classified as experiencing severe rainfall deficiency, with some areas in the far west at their lowest on Record

In the year to date parts of the Upper and Lower Western and Central West Slopes and Plains have received less than 20% of their average rainfall, with large parts of Riverina and North West Slopes and Plains not faring much better at less than 40%.

Rainfall over the last week has had little to no impact on these deficiencies at all with dry conditions continuing over most of NSW.

A frontal system due to move across the state late on Thursday into Friday should deliver some much needed rain, however at only around 1-5mm it is unlikely to have a huge impact on the current deficiencies.

Whilst the system does look to bring some rainfall, the far northwest of the state looks to remain without, with only a millimeter or so forecast for parts of Upper Western.

A second system moving across the south of the state early next week should top up falls across southern parts of Lower Western, Riverina and Southwest Slopes and Plain, with another 1-5mm forecast.

Looking further ahead the outlook remains grim, with below average rainfall expected into August and the chance of an El NiƱo looming.

Weather News - Wet week for the Southwest

Lachlan Maher, 21 July 2018

While showers and rain have been lingering over southern regions of Western Australia, there are no signs that clear skies are going to return any time soon.

Several frontal systems are expected to cross the southwestern parts of WA over the coming week, keeping the wet, windy and cloudy conditions that have been affecting the state for the last week.

Since last Sunday, a mix rain and lingering shower has led to about 33m of rain being recorded in Perth. Other nearby sites recorded similar amounts, the gauge at Bunbury receiving around 28mm. While these lingering showers briefly gave way to prolonged periods of clearer skies in the middle of last week, they are expected to return over the coming week.

Two fronts, one crossing over the weekend and another crossing on Wednesday look to bring some fair rainfall totals into the region. As the fronts cross, they may also trigger a few thunderstorms, though they are more likely just offshore.

While showers will linger throughout the week, most of the rain should come as the fronts pass through. By next Sunday, totals of about 40-60mm can be expected around Perth and Albany, while the far southwest may see 60-80mm over the week.

Following the second front, skies look to clear briefly as a weak high develops. Unfortunately for those that would like such weather to linger, more fronts look to cross before the month ends, bringing a return to rainy conditions.

Weather News - Wild weather sets its sights on New Zealand

Kim Westcott, 21 July 2018

A deep cold front will move over New Zealand, bringing an intense bout of wind, rain and snow.

The heaviest of the rain will be centred in the South Island, with Fiordland and Westland looking to pick 120-160mm in the rain gauge from this system. Other regions such as the Bay of Plenty, Mount Taranaki, Tarura Ranges and about the Otago/Canterbury headwaters are also under a heavy rain watch.

Thunderstorms should mainly be confined to the western parts of the South Island this afternoon and evening, slowly moving north overnight. Storms could be severe, and may bring heavy rain, strong winds and small hail.

Strong winds will also feature heavily with this system, with gusts to reach around 120km/h for the Malborough, Wellington and southern Wairarapa, Canterbury high country, Fiordland and Southland.

In it's wake, snow looks to develop, down to 400m around the Otago, Southland and Fiordland regions. Snowfall could be heavy at times above 600m, with as much as 15cm over nine hours possible.

Unfortunately for those who are relying on some steady sunshine, this system could linger for several days as it gradually weakens.
