* US weather concerns rise as corn crops enter key period

CHICAGO, June 14 (Reuters) - Chicago Board of Trade corn futures eased on Friday after hitting a two-week high a day earlier, as global crop weather looked mixed and strength in the dollar made U.S. farm products less attractive to importers, analysts said.

Wheat and soybean futures also declined. Traders are monitoring U.S. weather as corn crops approach a key development period in July, while winter wheat harvesting is gathering pace. Forecasts showing rising temperatures and limited rain in parts of the Midwest next week ignited concerns about potential stress for corn plants, though the crop is currently in good condition, as are soybeans.

The weather models range in their predictions for hot, dry conditions, said Don Roose, president of brokerage U.S. Commodities.

"This week probably marked the start of the weather watch, and that can be both ways," he said. "It's a footrace to see what the weather looks like going forward."

Most-active CBOT corn futures were down 4-1/4 cents at $4.54-1/4 a bushel by 10:55 a.m. CDT (1555 GMT).

CBOT wheat was down 3-1/2 cents at $6.16-1/2 a bushel, hovering near its lowest level since early May. Soybeans fell 4-1/4 cents to $11.85-1/4 a bushel to also trade near a one-month low.

The U.S. Department of Agriculture is slated to release weekly condition ratings for U.S. corn and soy crops on Monday, and analysts said they expect slight declines. Traders are also waiting for USDA to issue U.S. plantings and quarterly stocks data on June 28.

In the Black Sea region, the return of rain to dry parts of Russia and Ukraine was providing relief for corn, though benefit for wheat may be limited with harvesting looming, analysts said.

"We're into a world weather market as we head to the end of the month acreage and stocks reports," CHS Hedging broker Phyllis Nystrom said in a note. (Reporting by Tom Polansek in Chicago, Gus Trompiz and Mei Mei Chu in Beijing; editing by Jason Neely and Rod Nickel)
