CBOT seesaws on strong dollar, snow in wheat belt

March 21 (Reuters) - Chicago Board of Trade wheat futures traded both sides of unchanged before ending higher on Friday as traders assessed a rising dollar and a week with snowy weather in the U.S. Plains.

• CBOT May soft red winter wheat WK25 settled up 1 cent at $5.58-1/4 a bushel.

• K.C. May hard red winter wheat KWK25 ended up 2-1/4 cents at $5.88-3/4 per bushel and Minneapolis May spring wheat MWEK25 rose 1/4 cent to $6.05 per bushel.

• For the week, most active wheat Wv1 was up 0.22%.

• The dollar firmed against the euro on Friday, as investors took profits from the currency's recent advance, and as an April 2 deadline for reciprocal U.S. tariffs approached.

• A stronger dollar tends to make U.S. exports more expensive and therefore less competitive on the global market.

• Analysts said traders are exiting positions prior to the weekend because of anxiety over any news that could break and contribute to current economic uncertainty.

• Snowy weather this week in parts of the U.S. wheat belt provided needed precipitation to the crop.
