Wheat futures edged lower on forecasts that rain will fall in Kansas and Nebraska in the coming days, helping the outlook for this year's crop.
The price of wheat for March delivery fell 2 cents to $7.63 a bushel. The price of the grain has now fallen for three days.
Wheat is currently in its winter dormancy period, before it starts growing again in the spring.
"The amount of moisture becomes crucial as the wheat gets ready to break dormancy and really utilize a lot of moisture," said Mike Zuzolo, president of Global Commodities Analytics and Consulting in Lafayette, Indiana.

Corn for March delivery dropped 1.75 cents a bushel, or 0.2 percent, to $7.3425 a bushel. Soybeans rose 14.50 cents, or 1 percent, to $14.8875 a bushel.
