Thunderstorms, 'cold front': This week's weather

THUNDERSTORMS and heavy rain have been forecast for parts of the Northern Rivers today, according to the Bureau of Meteorology.

"A very strong, slow-moving high pressure system south of Tasmania is extending a ridge along the New South Wales coast and a low pressure trough lies off the central and north coasts," the bureau explains on their website.

"The trough is directing very moist and unstable onshore winds bringing heavy rain and thunderstorms across the parts of north and central coasts.

"Meanwhile, another trough lies over the northwestern parts of the state.

"Both troughs will weaken on Friday as the high moves towards New Zealand strengthening the ridge to the northwest.

"The next cold front is expected to cross the state during Sunday."
