A low pressure system and upper cold pool of air is expected to track in a north-easterly direction across central and eastern parts of SA this afternoon and overnight, with showers, light rain periods and isolated gusty thunderstorms.

Into the evening, a strengthening low-level jet is expected to help enhance high based thunderstorms across northern regions of the state where the potential will exist for localised damaging wind gusts.
Rainfall totals of less than 10mm are expected, however an isolated fall or two up to 20mm will be possible, particularly with any storm activity.
Conditions will gradually ease from the west overnight into Friday with fresh southerly winds moving into the region.
