CHICAGO, June 24 (Reuters) - Chicago Board of Trade (CBOT) soybeans rose on Monday as flooding hit the upper Midwest after a weekend of thunderstorms.

Corn fell on acreage expectations ahead of a USDA report on Friday and wheat was down with analysts citing U.S. harvest pressure. CBOT most-active soybeans settled up 14-3/4 cents at $11.75-1/4 a bushel. Storms marched through the Midwest over the weekend, with localized flooding in Minnesota, Iowa and Wisconsin threatening the soybean crop, said analysts.

"We've had a lot of water in the upper Midwest and soybeans really struggle underwater, more than the corn market, more than the wheat market," said Don Roose, founder of U.S. Commodities.

The USDA said on Monday after the market closed that U.S. soybeans were 67% in good to excellent condition vs. 70% a week ago, slightly below analysts' expectations.

Corn settled down 1-1/2 cents at $4.33-1/2 per bushel and wheat settled down 9 cents at $5.52-1/2 per bushel.

Angie Setzer, partner at Consus Ag Consulting, said corn prices fell because analysts expect an updated acreage report to show an increase in corn acres compared with data in late March.

Analysts polled by Reuters forecast 90.353 million acres of corn have been planted with corn, up from 90.036 million forecast in March.

The USDA said U.S. corn was 69% in good to excellent condition vs. 72% a week ago, in line with expectations.

Setzer added funds may be punishing farmers ahead of first notice day on Friday because of "the idea that the farmer has an extensive amount of unsold supply."

Wheat prices also faced pressure from the advancing U.S. harvest, said Roose. He estimated that winter wheat in the U.S. will be around 50% harvested by midweek.
