December corn opened 7 1/2 cents higher on the day at 601 1/2 and established an early range of 585 3/4 to 603. The corn market opened higher in line with soybeans. Traders said that the early strength stemmed from a sharp rally in crude oil prior to the open as well as a lower dollar. These factors were also thought to have supported the markets overnight. However, the weather forecast shifted again this morning. Rather, actual rains moved through Iowa and Minnesota this morning and the remnants of Tropical Storm Fay brought good coverage to southern and eastern Ohio. Floor traders said that news of this rain in formerly dry areas of the Midwest, with forecasts of further rains tomorrow and Friday, sent the corn market lower into mid session. Spreaders were actively buying corn and selling wheat early in the session, and this continued as both markets moved lower. Basis levels for corn were steady to firm in the interior this morning. Movement is said to be very slow.
