A hot air mass is blazing across SA, however this heat will fuel widespread and potentially severe thunderstorms over the state on Monday.
More than half of South Australia had its hottest day since summer with much of the Pastorals tipping 40 degrees. Today was Adelaide's hottest day since April, reaching 34.5 degrees by 3pm.
The heat will continue tomorrow, however cloud associated with a deepening trough will limit heating for most areas.
This trough has already begun causing potentially severe thunderstorms in the Northwest Pastoral and West Coast districts today. These storms bring the risk of damaging winds.
Severe thunderstorms are a significant risk for large portions of the state tomorrow as the trough deepens and moves east. The most at risk areas are the agricultural areas including Adelaide, where storms bring the potential for damaging wind gusts as well as flash flooding.
