July corn opened 3 1/4 cents lower on the day session at 626 and established an early range of 614 1/2 to 626 1/4. The corn market was expected to open higher on the day, but opened lower and sold off sharply early in the session. Traders indicate that the sell off came in response to improved weather forecasts for the corn belt this week which should allow a better-than-expected planting pace from the middle of this week into the weekend. The USDA will issue its Crop Progress Reports this afternoon at 3 pm and traders are expecting progress at about 45-50% according to floor traders. This compares to 71% planted at this time last year and a 10-year average of 72%. This week's export inspections were 34.263 million bushels. Weekly inspections of 48.084 million bushels are needed to reach the USDA projection. Total inspections to date stand at 68.7% of the USDA forecast for the season compared to a 5-year average of 64.5% for this time of the year.
