Continued concern over decreasing new crop corn yields due to blistering temperatures this week continued to support the corn market. Afternoon weather maps called for a little warmer 1- to 5-day forecast for the northern U.S. Extreme heat is expected to stick around for another 3 to 4 days in the central and southern Midwest. Changes also include a chance for better rainfall in the Midwest and western U.S. plains in the 6- to 10-day map.

Ethanol production

Ethanol production for the week ending June 29th averaged 857,000 barrels per day. This is down 2.9% vs. last week and down 5.2% vs. last year. Corn used in last week's production is estimated at 91.3 million bu., posting a new 16-week low and displaying further signs of demand destruction from the rally in corn. Corn use needs to average 98.25 million bu. per week to meet 2011/2012 USDA estimate of 5.05 billion bu. Ethanol stocks as of June 29th were 20.3 million barrels, which is also a 16-week low. This is down 2.2% vs. last week but up 9.3% vs. last year.

The Brazilian government adjusted their 2011/2012 corn crop production to 69.48 million tons, nearly 2 million tons higher than their last revision.

Outside markets are offering minimal resistance as the U.S. dollar surged over 1% and stocks were marginally weaker.
