* Forecasts of cool, wet weather in the U.S. Midwest weighs
* Chicago wheat prices on course for small weekly loss (Adds quotes, updates prices)
LONDON, June 23 (Reuters) - Chicago corn and soybean were slightly higher on Friday but remained on track for weekly losses as cooler temperatures in the U.S. Midwest helped to improve the outlook for crops.
The Chicago Board of Trade most-active corn contract was up 0.3 percent at $3.64 a bushel at 1041 GMT but was course for a weekly loss of 5.2 percent.
Corn and soybean prices are being pressured by more mild temperatures moving into the U.S. Midwest crop belt. The month of July weather is crucial for determining yields of the U.S. corn crop.
"Weather concerns for U.S. corn and soybean crops have eased, both markets in bearish mood," said Kaname Gokon of Tokyo brokerage Okato Shoji.
CBOT's most active soybean contract was up 0.4 percent at $9.07-1/2 a bushel but was on track for a weekly loss of 3.4 percent.
"The trend for soybean prices has been clearly downward so far this year, with South American supply growing and expectations of another large U.S. harvest weighing on the market," ING said in a market update on Friday.
Wheat prices followed a similar trend, posting modest gains on Friday after falling earlier in the week.
CBOT's most-active wheat contract was up 0.4 percent at $4.63-1/4 a bushel and was on course for a marginal weekly loss of 0.4 percent.
Much-needed rainfall is forecast in the coming days in the northern U.S. Plains, where the spring wheat crop has been suffering from dry weather, while in France the extent of damage from extreme heat is unclear.
December milling wheat in Paris was up 0.1 percent at 177.75 euros a tonne.
"In the EU, the recent heatwave has pushed markets higher. However, as in the U.S., a cooler forecast for France has seen the market retreat from the recent highs," David Sheppard, managing director of UK merchant Gleadell said in a market note.
Soggy spring conditions in key crop-growing areas of the Canadian Prairies left farmers unable to plant as much as they intended, but canola seedings still look record-large, according to a Reuters survey of 16 traders and analysts, ahead of a government report next week.
