US corn, soyabean and wheat futures rose on Tuesday, rebounding from weakness in the overnight session after finding technical support, traders said.

Soyabean futures peaked at their highest since July 19 while corn hit its highest since August 12.

Forecasts for a snowstorm in northern stretches of the US Midwest also added support to prices, as the wintry weather raises the prospect of crop damage and further delays to an already slow harvest.

At 10:47 am CDT (1547 GMT), Chicago Board of Trade November soyabean futures were up 4-/12 cents at $9.19-3/4 a bushel. Prices traded lower before finding support at the contract's 200-day moving average.

CBOT December corn was up 5-3/4 cents at $3.92-3/4 a bushel.

CBOT December soft red winter wheat was up 5-1/2 cents a bushel at $4.94-3/4, turning higher after early weakness pushed it near its 20-day moving average.

The storm was expected to drop between six and 12 inches of snow in major crop production states such as North Dakota, Minnesota and South Dakota, forecaster Commodity Weather Group said.

In its weekly crop update on Monday afternoon, the USDA said 15% of the corn crop had been harvested as of October 6, below analysts' forecasts and lower than the average pace of 27%. On the soyabean crop, the USDA said 14% had been harvested, slightly behind market forecasts. The five-year average is 34%. Traders were waiting for the US Department of Agriculture's (USDA) latest crop forecasts, which will be released on Thursday. The market has become more sensitive to any setbacks in harvest yields after the USDA put quarterly stocks of corn and soyabeans below expectations in a report at the end of September.
