Wet conditions are expected to return to eastern Queensland and northern NSW later this week, as an upper trough combines with a surface trough and southerly change.
Late Wednesday and into Thursday, a southerly change will move through northern NSW and southern QLD bringing increasing moisture with scattered showers and gusty winds.
This upper system will move into South Eastern Queensland overnight Thursday and into Friday, combining with increased moisture from the southerly change with the potential for a small coastal trough to develop.

In response, scattered showers, tending to rain and isolated thunderstorm will be possible from the Mid North Coast of NSW to the Wide Bay and Burnett region in QLD, with localised heavy falls to 100mm across coastal regions. Areas 10-20km inland are expected to see lighter falls, with 5-15mm possible.
