Many of SA's dry agricultural regions were inundated with heavy rainfall yesterday and today, bringing a sigh of relief to many. Nullarbor received a total of 40mm of rainfall and Ceduna saw 24mm to 9am this morning, both their heaviest falls since February 2011. Adelaide accumulated 15mm by 11:30 this morning, which is the heaviest two-day total they've seen since October last year. Further east, Clare gained 10mm making it their heaviest April fall in four years. This widespread rain was caused by a broad low pressure trough moving over the region. The trough is expected to move in an easterly direction over the coming days, causing showers to ease. A few isolated showers are expected on Monday, with cloud remaining around southern and eastern parts of the state over the coming days in the wake of the trough.
