Prevailing climatic conditions during 1997 - May through October

Winter wheat harvest started late in the Northwest because of cool and wet weather in the spring. August rainfall helped to revive central Corn Belt crops that were stressed by dry, occasionally hot weather during July. Farther west, a persistent flow of tropical moisture became established across the Southwest and the High Plains in late July, continuing through summer's end. Brief hot spells punctuated the summer of 1997 across the Midwestern and Eastern states, but temperature overall averaged slightly below normal.
