Spring-like thunderstorms brewing over NSW and QLD

Joel Pippard, Thursday August 23, 2018 - 13:11 EST

With the rain event approaching northern New South Wales and southern Queensland, severe thunderstorms may develop this weekend; something that's quite unusual for this time of year.

The cut-off low that will kick things off is currently making landfall over South Australia and will move over NSW on Friday.

Northeasterly winds will feed warm, moist air from the Pacific Ocean into this low and accompanying trough from Saturday, bringing widespread rainfall over the eastern border region of NSW and QLD.

Apart from the rainfall this system will bring, the mixture of warm, moist air at the surface and cold air up high bring all the ingredients needed for thunderstorms to spark up over the region on Saturday and Sunday.

These thunderstorms could be severe with heavy rainfall, conducive to flash flooding, damaging winds, possibly downing trees and powerlines, and even some hail.

The most likely areas to see thunderstorms are from QLDs' Central West district all the way down to the Central Tablelands, Slopes, and Plains in NSW. Thunderstorms are also a decent chance on the eastern side of the ranges from Capricornia QLD to the NSW Illawarra region, including both Brisbane and Sydney.

Severe thunderstorms are usually seen in the middle of summer but start to become more frequent during the spring months (sometimes known as the 'build-up season'). However, this tends to occur in late September and October, rather than in August.
