Corn and soybeans remain on the plus side by double digits so far Wednesday, bringing wheat with them in mid-day trading.

At mid-day, nearby corn futures are 10 3/4 cents higher per bushel at $7.63 1/4, while nearby soybeans are 13 cents higher at $13.42 3/4, according to Barchart.com. Nearby wheat is 2 1/2 cents higher at $7.62 per bushel.

Concerns about tight domestic corn stocks and a weather forecast that could result in a lot of planters sitting still the next few days are largely fueling Wednesday's uptrend. That latter factor could be in the mix for several days from now, according to meteorologist Craig Solberg.

"We will see one more nice day in the Midwest for this Wednesday (i.e. largely dry conditions, mild temperatures) but things will be going downhill in the west tomorrow, in the east on Friday...and it may then be quite a while before we again get into any sort of 'nice' weather pattern for the region," Solberg said Wednesday morning.
