Prevailing climatic conditions during 1990 - May through October
Moisture was very short to short most of the Southeast and
western Corn Belt, causing deteriorating crops and pasture conditions. Winter wheat
seeding slowed due to inadequate moisture. Generally, the precipitation pattern shows that
Northeast, East North Central, and Northwest regions experienced wet condition while dry
conditions prevailed across the Southeast and South regions. Six States in the South or
Southeast had the 10th driest or drier summer on record while another six in
the Midwest had the wettest summer in 1990. Unusual warmth prevailed across the country
except in the Central and East North Central regions. Temperatures for the summer 1990
averaged across the contiguous United States were above long-term mean and ranked as the
15th warmest on record.
