CHICAGO, June 10 (Reuters) - U.S. wheat futures hit their lowest in more than a month on Monday on seasonal pressure from the expanding Northern Hemisphere harvest, forecasts for beneficial rains in the Black Sea region and worries about demand following Turkey's ban on wheat imports, analysts said.

Corn and soybean futures firmed, consolidating after last week's multi-week lows as traders awaited updated weekly U.S. crop ratings due later on Monday from the U.S. Department of Agriculture.

As of 12:52 p.m. CDT (1752 GMT), Chicago Board of Trade July wheat was down 17-1/2 cents at $6.10 per bushel after dipping to $6.08-1/4, the contract's lowest since May 3.

CBOT July corn was up 3 cents at $4.51-3/4 a bushel and July soybeans were up 7-3/4 cents at $11.87 a bushel.

CBOT wheat fell more than 2% on talk of strong early yields as the harvest progressed in the southern U.S. Plains, and as parts of Russia looked set to receive much-needed moisture.

"Yields in Oklahoma have generally impressed, coming in better-than-expected, albeit with lower than hoped protein content," StoneX chief commodities economist Arlan Suderman wrote in a client note.

Ahead of the USDA's weekly crop progress report due later on Monday, analysts surveyed by Reuters on average expected the government to show the U.S. winter wheat harvest as 13% complete, up from 6% a week ago.

Suderman also noted "a modest shift in the forecast that allows showers to provide relief for some parched portions of southern Russia and eastern Ukraine, benefiting both corn and wheat ground."

Traders continued to digest news that Turkey will halt wheat imports from June 21 to protect farmers. The country is the world's fifth largest wheat importer, buying mostly from Russia.

"This would mean that Black Sea wheat, especially Russian, which would have gone to Turkey may now be sold elsewhere in competition to U.S. and other exporters," said Matt Ammermann, StoneX commodity risk manager.

Weekly U.S. corn ratings were seen declining slightly from last week's strong levels. Analysts surveyed by Reuters on average expected the USDA to rate 74% of the corn crop in good to excellent condition, down from 75% last week.

Analysts expected the government to rate 72% of the soybean crop as good to excellent in its first weekly ratings of the oilseed crop for 2024. (Reporting by Julie Ingwersen; additional reporting by Michael Hogan in Hamburg and Naveen Thukral in Singapore; Editing by Aurora Ellis)
