After a couple of days with cooler temperatures, another quick round of heat will be spreading west to east across southern and eastern states.
A trough over western WA will be dragging heat towards the coasts as it marches east.
First one up will be SA, with Adelaide set to reach the low 30s. It is unlikely the City of Churches will reach the 39 degrees achieved last Thursday (14 degrees above the norm). This is only expected about the northern districts. After a brief cooling, Saturday will see temperatures soar again to the low 30s ahead of a more significant cool change from Sunday.
Melbourne will see some warming, reaching the high 20s (about five degrees above the norm). The City on the Yarra, however, is likely to see its hottest day on Saturday with temperatures climbing to the low 30s.
Sydney, the Emerald City, will see this heat arriving on Thursday. The hot airmass will linger on Friday with a cool change providing some brief relief on Saturday. Heat will return once again on Sunday and Monday, with the mercury reaching the low 30s. In all, the city will be spared from the bulk of the heat thanks to the cooling effect of the afternoon sea breezes. Western suburbs, however, are likely to reach the mid-30s on Thursday, Friday and again on Sunday.
Brisbanites will be at the tail end of this heat event. However, Brisbane is unlikely to reach the high 30s as it did over the weekend (Sunday reached 38.9 degrees, its warmest November day in 46 years). Afternoon sea breezes will keep temperatures at bay but will make it feel a few degrees warmer, mainly on the afternoon and at night. Muggy conditions are likely to make a few of these nights quite unpleasant.
Next week is looking to be relatively cool with no significant heat events until the official start to summer.
