South Australia’s unusual summer has notched another quirk after thunderstorms and rain hit much of the state overnight.

The latest thunderstorms to sweep SA dumped 6.8mm of rain in the city, 15.6mm at Loxton, and 12.4mm on Mt Lofty.

The wettest parts of the state on Tuesday were Mount Mary with 35mm, Roxby Downs in the Far North with 28mm and Yunta in the northeast with 23mm.

Bureau of Meteorology meteorologist Jenny Horvat said Adelaide’s January 2024 rainfall had now already surpassed that of the whole of January last year.

“For the whole month of January 2023 we’d only recorded 17.4mm of rain (in Adelaide) and actually we didn’t see any rain up until about this time of year – so it was a dry start for the first two weeks of last year,” Ms Horvat said.

“But in 2024 we’ve already had 20.6mm of rainfall this January.”

Adelaide’s average rainfall for January is 20.1mm.

Thunderstorm activity is clearing from much of the state but will hover in parts for a little longer, Ms Horvat said.

“(On Tuesday), we did see quite a lot of thunderstorm activity across the state and some severe storms,” she said.

“The thunderstorms will contract up to the far northeast on Thursday and it will linger there into the weekend … but elsewhere the conditions are much more settled.”

Adelaide is expected to reach a partly cloudy top of 23C on Wednesday, with southwest winds of 25-40km/h.

The weather will gradually heat up with Thursday forecast to hit 25C, Friday 29C and Saturday a hot 34C.

In Mount Gambier, showers are forecast to linger on Wednesday and Thursday, with temperatures of 20C and 21C.

Port Lincoln is forecast to be at 21C on Wednesday, then moving up to 22C on Thursday and 24C on Friday.

Meanwhile, it will be warmer in the Riverland with Renmark to reach a top of 28C on Wednesday and Thursday before jumping to 30C on Friday.
