Very dangerous thunderstorms will affect parts of Queensland and northern NSW today.

Moisture-laden air feeding into a low pressure trough and interacting with an upper-level cold-pool will trigger a large number of thunderstorms between central Queensland and central NSW on Wednesday.

Storms will develop from the late morning and become more widespread and intense during the afternoon, with some storms even persisting into the evening.

Thunderstorms are likely to develop over a broad area stretching from about Townsville in Queensland down to the Central West Slopes and Plains in NSW.

The most violent thunderstorms, which could develop into supercells, will emerge over central and southeast Queensland and northeast NSW, roughly between Rockhampton and Coonabarabran. These storms could produce damaging-to-destructive winds, large-to-giant hail and heavy rain causing flash flooding.
