Almost 4000 properties across South Australian remain without power after storms lashed the state, with 300,000 lightning strikes reported over a wide area.

SA Power Networks said its crews were continuing to return services to customers across the Adelaide Hills, the mid-north, on Yorke Peninsula and in the southeast after the wild weather on Tuesday night.

At one stage more than 32,000 of its customers lost electricity with the storms also sparking a spate of scrub fires.

Fires on Yorke Peninsula prompted the Country Fire Service to issue a watch and act warning for a number of towns including Minlaton, Edithburgh, Cabowie, Yorketown and Stansbury.

Warnings were later downgraded to a bushfire advice message.

The storms came after a day of extreme heat across most of the state and were the result of a vigorous trough which moved in from the west.

The mercury peaked at 38.5C in Adelaide on Tuesday, making it the city's hottest day since January.

Other regional centres reported higher temperatures with Oodnadatta, in the state's north, reaching 43.6C.

A severe weather warning was issued at one stage for large areas of SA, from the far west, stretching through the mid-north and across the Adelaide Hills, but conditions had moderated by Wednesday morning.

Meteorologist Jenny Horvat said high winds were also reported across a wide area, with the strongest gust of 119 km/l recorded at Edinburgh, in Adelaide's north.

However, the system brought little in the way of rain, with Bordertown, in the southeast, doing the best with 18.8 millimetres.

Ms Horvat said such storm activity was not unusual for SA in spring and conditions were forecast to moderate in the coming days.

On Wednesday, Adelaide had a top of just 25.3C with even cool conditions expected on Thursday and Friday.
