* Chicago wheat futures drop after climbing to two-week high
* Spotlight on U.S. supply-demand report amid weather concerns
SINGAPORE, Aug 12 (Reuters) - Chicago wheat futures snapped a four-session winning streak on Friday, with the market dropping from a two-week high, as investors squared positions ahead of a key U.S. report on global supply and demand.
Corn and soybeans edged lower, although concerns about hot and dry weather conditions in the U.S. Midwest limited losses.
"For the 1-5 day forecast, there are light scattered rains for Nebraska, eastern Iowa and Minnesota, with no rain in the forecast for South Dakota, southwestern Minnesota and western Iowa. There is also no rain for Illinois," according to a Hightower report.
The most-active wheat contract of the Chicago Board of Trade (CBOT) was down 1% at $8.02-3/4 a bushel, as of 0217 GMT, after climbing to its highest since July 29 in the previous session at $8.21 a bushel.
Corn lost 0.3% to $6.26 a bushel and soybeans gave up 0.4% to $14.43 a bushel.
For the week, all three markets are set for a positive finish after closing lower last week.
Parts of the U.S. Midwest received rain in recent days, but heat in the western regions of the farm belt is expected to continue to hurt crops, including soybeans going through a key growth phase.

However, rains seen in recent weeks in Argentina's agricultural areas allowed producers to finish planting their 2022/23 wheat crop and recharged moisture levels before the next key phases of crop development, the Buenos Aires grains exchange said on Thursday.
