Worries about lightened demand that sent the grains lower Wednesday afternoon seem a world away Thursday, with all CME Group grains trading higher as the mid-day point rolls around.

At mid-session, nearby corn's 21 1/4 cents higher at $7.25 1/4 per bushel, nearby soybeans are 10 1/2 cents higher at $15.33 and nearby wheat's 19 1/4 higher at $15.33, according to Barchart.com.

Despite downward pressure following USDA's release of lower demand numbers for feed usage and exports in Wednesday's WASDE report, the dominating theme returned to Mother Nature on Thursday. And, though there's been a lot of anxiety about what the weather's done to the crop already, there's also a lot of worry about the trend moving forward; with the heat expected to crank up again next week, traders see reason to trade the grains higher, reports show.
