After an overnight trade and start to Wednesday spent in the red, the grains have rebounded and are trading higher at mid-day.

At mid-day, March corn has moved 4 1/4 cents higher to $6.11 1/4 per bushel, January soybeans are 5 1/2 higher at $11.50 and March wheat is 4 1/4 higher at $6.12, according to Barchart.com.

The reversal comes after a lower start to Wednesday's trade after word of much-needed rainfall in the corn- and soybean-growing regions of Argentina and southern Brazil. But, crop concerns there linger despite the moisture, as many forecasts call for a return to crop-stressing weather soon.
