Another heatwave is ready to steam roll the region in the coming days.

Tomorrow will be very hot with cloud increasing and widespread storm development as a trough passes over.

This will trigger a weak change that will only affect Gosford and Newcastle on Saturday, with onshore winds keeping temperatures down on the coast.

Inland will still be hot.

On Sunday things will get very nasty with many areas headed into the high 30s and low 40s.
