As a savage coastal low battered the NSW coast with torrential rains, flooding and massive surf, it also dropped another round of soaking rains across parts of the state's cropping areas.
Inland rainfall was patchy, with the central west recording the heaviest falls and lighter rain to the north and south.
Cowra was drenched with upwards of 80 millimetres from Sunday through to Tuesday, resulting in localised flooding.
Further west, Condobolin, Nyngan, Trangie, Peak Hill, Coonamble and Walgett had 20mm to 30mm.
The soaking rains have left large areas of the state's expansive winter wheat production areas saturated heading into spring.
Heavy falls around Cowra and Bathurst will provide valuable inflows in water storages that remain depleted after years of drought.
Rainfall totals quickly tapered away to the north and south. Moree and Narrabri in the north west received less than 10mm for the week. Similarly, Lake Cargelligo, Griffith and Yanco to the south missed most of the rain. Central west farmers are making the most of the rain, with many taking the opportunity to top-dress canola crops.
Old crop grain markets remain fickle with tight supplies and shrinking demand with most of the attention switching to the new crop.
New crop wheat prices drifted lower last week with the strength in the Australian dollar, but the dry weather is supporting southern Queensland prices.
New season barley prices edged higher in NSW and Victoria after a large optional origin purchase by Saudi Arabia, where prices were sharply higher than the previous tender in June.
Global wheat markets continue to find support on lower than expected yields in Russia and slow farmer selling.
The International Grains Council lowered its forecast for global wheat production for the 2020/21 season by six million tonnes to 762mt, after reductions in the European Union, Russia, US and Argentina.
Russian wheat production was lowered by 1mt to 78mt, which is still six per cent higher than last year due to the larger plantings, IGC said.
Australian wheat production was left unchanged at 26.2mt.
Major exporter wheat stocks are forecast to decline by 4mt to 62mt, despite a 2mt reduction in global wheat trade, IGC said.
Global barley production is set to fall by around 2mt from last year's record harvest to around 150mt, linked to smaller plantings.
Global output is expected to remain large due to large crops in Australia and Canada, IGC said.
