Gusty northerly winds are likely to raise dust across parts of South Australia today before dirty rain develops. The dry, mild-to-warm northerlies have potential to pick up dust in northern and western parts of the state and send it many kilometres to the south. By the time rain develops the wind will be easing in most areas but it should still be dusty enough for the initial light rain to come down muddy. This is most likely to occur in the northwest where it will be windiest, the ground is driest and rain will be light. Not an ideal day to wash the car or hang out the washing. Wind should gust to 50-70 km/h in the west and north early in the day then also in the south later in the day before spots of dirty rain develop. Wind of this strength is always a worry at this time of year. Maturing grain crops are at risk of being damaged which would be a blow given the reasonable grain prices on offer. For the state's West Coast and South East, winter rain was above average but elsewhere was generally below so some growers are sitting on a knife edge regarding the spring weather. Unfortunately, for most of the state today, the rain will not compensate for the wind, amounting to just a few millimetres at the most. When a front moves through the south tomorrow it also looks fairly lean in terms of rain, potentially more than 10mm for the Lower South East, but just a few millimetres or less elsewhere in the south.
