Brisbane was shrouded in a winter wonderland on Tuesday morning as thick low cloud blanketed the inner-city and northern suburbs.

A mixture of cool overnight temperatures, moisture and clear skies were responsible for the River City's extra blanket and there could be more on the way this week.

Weatherzone meteorologist Graeme Brittain said there had also been fog on Monday morning, but it was quite isolated and mainly in low-lying areas to the north and inland.

"There were patchy areas of fog over the greater Brisbane area this morning and it was a bit more dense and widespread to the north of Brisbane," he said.
