South Australia is bracing for another round of scorching heat, with temperatures and fire danger set to soar once again.
A hot airmass is building over SA today ahead of a low pressure trough, pushing the mercury into the high 30s across much of the state. A top of 36 degrees is forecast for Adelaide, which is six degrees above average. Ceduna is set to reach 39 degrees, with a top of 42 degrees in Coober Pedy.
Thursday will be the real scorcher with winds tending northwesterly and becoming gusty as the trough draws near. Much of the state is expected to warm into the low 40s. Adelaide is expecting a top of 41 degrees, which would make it the fourth time this month that it has exceeded 40. Parafield and Wudinna should heat to 44 degrees. This is 14 degrees above average for Parafield.
The extreme heat and dry, gusty winds will elevate fire danger across the state once again, so those in high risk areas should be cautious and keep abreast of weather conditions and warnings.
A gusty, southwesterly wind change will sweep through the state's southwest during the afternoon, reaching Adelaide during the evening. This will bring relief in the form of cooling, however the wind change could pose a problem to fire fighters. Showers and thunderstorms are also possible with the change, most likely in the northern pastorals.
In the wake of the change temperatures will cool closer to average from Friday, with the fire danger easing.
