U.S. corn futures rose nearly 2% on May 19, 2017, to a one-week high as cool temperatures and excess rain in the Midwest led traders to cover short positions. Soybeans firmed after Thursday's selloff, and wheat climbed on wet conditions in winter wheat areas and a weaker dollar.
Flooding and poor emergence may force corn reseeding, and late planting cuts yield potential, supporting corn and wheat prices.
