The National Climatic Data Center (NCDC) has released its summary of the nation’s climate and weather for 2014.  Its analysis shows that overall, the United States experienced warmer than normal temperatures and above average precipitation.

From NOAA / NCDC:

2014 U.S. temperature exceeds 20th-century average for the 18th consecutive year

Second warmest December boosted 2014 to 34th warmest year for contiguous U.S; eight weather and climate disasters exceeded $1 billion in damages

The 2014 annual average contiguous U.S. temperature was 52.6°F, 0.5°F above the 20th century average. Very warm conditions dominated the West, with four states having their warmest year on record, while the Midwest and Mississippi Valley were cool. This ranked as the 34th warmest year since we began keeping track in the 1895, while the temperature exceeded the 20th Century average for the 18th consecutive year.

The average contiguous U.S. precipitation was 30.76 inches, 0.82 inch above average, and ranked as the 40th wettest year in the 120-year period of record. The Northern U.S. was wet, and the Southern Plains were dry; the national drought footprint shrank about 2 percent.

In 2014, there were eight weather/climate disaster events with losses exceeding $1 billion each across the United States. These eight events resulted in the deaths of 53 people. The events include: the western U.S. drought, the Michigan & Northeast flooding event, five severe storm events, and one winter storm event.

U.S. climate highlights: 2014

  • The West was warmer than average for much of 2014. Nine states had a top 10 warm year.Alaska, Arizona, California, and Nevada each had their warmest year on record. Most locations from the Rockies to the East Coast were cooler than average, with the exception of New England and Florida. Seven states across the Midwest and Mississippi River Valley had a top 10 cool year. No state was record cold during 2014.
  • The Pacific Northwest, Northern Rockies, Midwest, and Northeast were all wetter than average. Michigan and Wisconsin each had their seventh wettest year on record. The Southern Plains and parts of the Ohio Valley were drier than average, but no state was top 10 dry. The rest of the contiguous U.S. had near-average annual precipitation totals.
  • The U.S. Climate Extremes Index (USCEI) for 2014 was 35 percent above average, ranking as the 19th highest annual USCEI in the 105-year record. The components of the USCEI that were much above average for the year included warm nighttime temperatures and 1-day precipitation totals. The USCEI is an index that tracks extremes (falling in the upper or lower 10 percent of the record) in temperature, precipitation, drought, and land-falling tropical cyclones across the contiguous U.S.
