GRAINS-Prices bounce as crop data, trade moves watched

* Wheat rises after 3-day fall; corn, soy also higher

* Investors await USDA data, more signs of trade fallout

* Midwest weather seen as favourable but hot spell watched

(Updates with European trading, changes byline/dateline) PARIS/SINGAPORE, June 27 (Reuters) - Chicago grain and soybean futures rose on Wednesday as prices steadied following recent losses and investors awaited U.S. government crop data later in the week and more indications on the fallout of a U.S.-China trade dispute. September wheat futures, the most active contract on the Chicago Board of Trade, rose 1.2 percent to $4.89 a bushel by 1257 GMT, having fallen in each of the past three sessions. CBOT November soybeans gained 1.1 percent to $8.97-1/2 a bushel, while July corn added 1.0 percent to $3.56 a bushel. Worries over disruption to trade flows due to a standoff between Washington and Beijing, which are planning to target each other with import tariffs from next month, have weighed on financial markets including grains, with concern focused on massive U.S. soybean exports to China. "Grain markets are struggling to lift their heads as the tariffs go into effect on July 6," U.S. brokerage Allendale said in a note. "End of month and pre-report position adjusting will also be affecting price movement in upcoming sessions," it said, referring to the U.S. Department of Agriculture's (USDA) acreage and quarterly stocks reports on Friday.

Broadly favourable weather for U.S. corn and soybeans in the U.S. Midwest have also weighed on Chicago futures, although a hot spell forecast for the coming week was adding a little caution as corn and soy enter crucial summer growth periods. Swift progress in the U.S. winter wheat harvest has also offset concern about adverse weather in countries like Russia. "U.S. wheat harvest is progressing well and yields are not as low as expected earlier," said one India-based agricultural commodities analyst at an international bank. "Consumers are clearly not worried about wheat supplies." The U.S. Department of Agriculture late on Monday said the U.S. winter wheat harvest was 41 percent complete while the Kansas harvest was 52 percent finished, ahead of the state's five-year average of 32 percent. Australia's drought-hit eastern grain belt is forecast to get some rains which are expected to limit yield losses, although persisting hot, dry weather in southern Russia could curb yields in the world's top wheat exporting country. Commodity funds were net sellers of CBOT soybean, wheat, soymeal and soyoil futures contracts on Tuesday and net buyers of corn, traders said.
