Through climate analysis, National Climatic Data Center scientists have identified nine climatically consistent regions within the contiguous United States which are useful for putting current climate anomalies into an historical perspective.

Additional information about current climate anomalies can be found at the respective Web Pages of the Southern Regional Climate Center, Western Regional Climate Center, Midwest Regional Climate Center, Southeast Regional Climate Center, High Plains Regional Climate Center, and the Northeast Regional Climate Center.

June-August 2000 was the second warmest such season on record for Utah and the third warmest such season since 1895 for Nevada. Four other states ranked within the top ten warm portion including
  • Wyoming -5th warmest
  • Colorado - 6th warmest
  • Arizona - 8th warmest
  • New Mexico - 8th warmest
Fourteen additional states ranked within the warm third portion of the historical distribution for summer 2000.

Fourteen states, all in the northeastern quarter of the country, ranked within the cool third of the distribution.

It was the fifth driest June-August on record for Alabama and the sixth driest such season on record for Florida. Fourteen other states ranked within the dry third of the distribution.

Nineteen states ranked within the wet third portion of the distribution including the sixth wettest June-August on record for Indiana and the seventh wettest such period since 1895 for North Dakota.

Preliminary data indicate that June-August 2000 was the 18th coolest such season since 1895 for the Northeast region.

It was the 13th driest summer on record for the Northwest. The predominant storm track has remained north of the region for the majority of the summer. Dry Region 6-8

NOAA works closely with the academic and scientific communities on climate-related research projects to increase the understanding of El Niño and improve forecasting techniques. NOAA's Climate Prediction Center monitors, analyzes and predicts climate events ranging from weeks to seasons for the nation. NOAA also operates the network of data buoys and satellites that provide vital information about the ocean waters, and initiates research projects to improve future climate forecasts. The long lead climate outlooks are available from the Climate Prediction Center.
