Thunderstorms have sparked up in Queensland and New South Wales and will continue to develop during Thursday afternoon and evening.
A low pressure trough is combining with moist southeasterly winds and high temperatures over eastern Australia, providing the ideal conditions for thunderstorm development.
Storms developed over the NSW Northern Tablelands between 1 and 2pm, east of about Glen Innes and Tenterfield, with a severe storm warning for damaging winds and large hail issued shortly after.
Thunderstorms also developed in central and southern QLD, around areas including Georgetown, Rolleston and to the south around Warwick. A severe storm warning was issued for the Darling Downs and Granite Belt and the South East Coast districts.
During the remainder of Thursday afternoon thunderstorms are possible over a vast area extending as far north as the QLD tropics to the NSW Mid North Coast. This includes Brisbane, where residents are still smarting from last weekend's stormy battering.
Whilst conditions are not looking quite as likely to become severe as on the weekend, the risk of damaging winds, large hail and flash flooding cannot be ruled out.
