It was the hottest night since last summer for some parts of South Australia, with Port Augusta seeing its hottest December night in three years.
The reason for the very warm night was due to the arrival of a hot airmass, which is filtering into SA ahead of a low pressure trough located over WA. For Lameroo, Clare and Port Augusta it was the hottest night since last summer. It was also Port Augusta's hottest December night in three years, with an overnight minimum of 25 degrees.
In Adelaide it also only cooled to 25 degrees overnight, nearly ten degrees above average, driving sleep-deprived locals to crank up their air conditioners. By 8:30am the state's capital had already reached 33, with an expected top of in the high thirties followed by another sweaty night ahead.
Thursday will be another hot day before the trough moves into western parts of the state, causing showers and possibly thunderstorms to develop. The trough will then sweep across the rest of the state on Friday bringing showers and gradual cooling, with temperatures closer to average.
