CHICAGO, May 19 (Reuters) - The following are U.S. expectations for the resumption of grain and soy complex trading at the Chicago Board of Trade at 8:30 a.m. CDT (1330 GMT) on Monday.

WHEAT - Up 1 to 6 cents per bushel

CBOT wheat futures higher for the fourth time in five sessions, supported by a weaker dollar which makes U.S. wheat more competitive in export markets.

South Korean millers bought about 50,000 metric tons of U.S. wheat in a tender on Monday.

Saudi Arabia bought 621,000 metric tons of optional-origin wheat via a tender for arrival in August to October.

CBOT July soft red winter wheat WN25 was last up 5-3/4 cents at $5.30-3/4 per bushel. K.C. July hard red winter wheat KWN25 was last up 8-1/4 cents at $5.24-3/4 a bushel, while Minneapolis July spring wheat MWEN25 was last up 4-1/2 cents at $5.77-3/4 a bushel.

CORN - Up 1 to 4 cents per bushel

Corn futures higher in a technical and short covering rebound, supported by a weaker U.S. dollar. Favorable Midwest crop conditions capping gains as recently planted corn fields are due to receive ample rain through midweek.

CBOT July corn CN25 was last up 3-3/4 cents at $4.47-1/4 per bushel.

SOYBEANS - Up 1 to 4 cents per bushel

Soybeans firm on short covering and technical buying following two sessions of losses. Gains capped by recent favorable U.S. Midwest weather that boosted soybean planting ahead of rains this week.

CBOT July soybeans SN25 were last up 3-3/4 cents at $10.53-3/4 per bushel.
