Prevailing climatic conditions during 1991 - May through October

Hot and dry conditions prevailed across the Corn Belt and into the Northeast. This summer was warmer than normal for the Nation as a whole. It was the 19th warmest season since 1895. In terms of precipitation, it was the 42nd driest on record. The Northeast region had the most anomalous warmth (8th warmest), followed by the East North Central and Central regions (both 12th Warmest). It was especially dry in the Central region (5th driest). Precipitation was significantly above normal only in the Southeast and the West. The high temperature in the Midwest sustained the early maturation of field crops. Soil moisture supplies remained mostly short in the Central States, and short to adequate in the Northwest.
