GRAINS-Chicago grains pause as dollar and weather weigh

BEIJING/PARIS, Jan 27 (Reuters) - Chicago grain and soybean futures were little changed on Tuesday, with a sliding dollar underpinning prices while attention turned away from the severe cold in the United States.

The most-active wheat contract Wv1 on the Chicago Board of Trade (CBOT) was down 0.05% at $5.22-1/4 a bushel by 1253 GMT.

CBOT soybeans Sv1 ticked up 0.19% to $10.63-3/4 a bushel while CBOT corn Cv1 inched up 0.12% to $4.28-3/4 a bushel.

On Monday, wheat set a six-week high, soybeans a four-week peak and corn a two-week top before all three crops finished lower, as fears subsided that a U.S. winter storm would damage wheat crops and disrupt grain logistics.

Weather worries in the wheat market were also fuelled by an intense cold spell in Russia, though, like in the U.S. Plains, snow was expected to limit possible crop losses.

"The market has reversed some of the gains over the past few days as fears of winter kill in Russia and the U.S. wheat belt diminished as adequate snow cover has protected the crop," said Andrew Whitelaw, founder of agricultural consultants Episode 3.

The dollar is facing pressure from factors including turbulence created by U.S. President Donald Trump's policy agenda, though share prices have continued to climb.

"Stock markets are up, and commodity currencies are performing well against the weak U.S. dollar," Peak Trading Research said in a note, calling the context bullish for grains.

Grain and soybean markets remained capped by ample global supplies, including a projected record Brazilian soybean harvest that traders expect China to turn to for imports in the coming months after a recent wave of U.S. soybean purchases.

However, availability of Brazil's new crop was limited for now, with harvesting still in its early stages and advance sales by farmers relatively slow, according to analysts.

"Agricultural producers in Brazil appear to be somewhat more selective in their negotiations due to what they consider to be too low prices," Commerzbank said.
