The Bureau of Meteorology in the lead up to christmas in 2018 showed a heatwave building through the week. The forecast was for severe and extreme heatwave impacts particularly Thursday 27 December to Saturday 29 December.
A blocking high in the Tasman and strong heat from the Pilbara in Western Australia and right through Central Australia, will periodically extend tendrils of sweltering heat to encompass the major population centres of Adelaide, Melbourne and Sydney.
While these cities may get occasional relief from weak cold fronts and coastal sea breezes, inland towns will swelter in the scorthing heat with temperatures in the mid to high 30s and low 40s.
