CHICAGO, Jan 21 (Reuters) - 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. CST (1430 GMT) on Tuesday.

WHEAT - Up 7 to 10 cents per bushel

* Wheat futures Wv1 up on spillover strength from soybeans and corn along with a setback in the dollar, which tends to make U.S. grains more competitive globally.

* Market players eyeing frigid weather in the U.S. Midwest and Plains that could threaten dormant winter wheat crops.

* Russian wheat export prices declined last week in the face of competitive offers from other global exporters.

* CBOT March soft red winter wheat WH25 was last up 9-3/4 cents at $5.48-1/2 a bushel. K.C. March hard red winter wheat KWH25 was last up 10 cents at $5.58-1/2 a bushel, and Minneapolis March spring wheat MWEH25 was up 7-1/2 cents at $5.91 a bushel.

CORN - Up 3 to 4 cents per bushel

* Benchmark corn futures Cv1 climbed to a 13-month high on worries about crop weather in Argentina, the world's No. 3 corn producer, and the fact that President Trump did not lay out any concrete plans regarding tariffs on close trade partners.

* Recent rains in Argentina's agricultural heartland have not alleviated concerns that ongoing drought could further hurt crop yields, the Rosario grains exchange said in a report released on Monday.
