National Overview:


February and Winter
  • The December 2006-February 2007 winter season was marked by periods of unusually warm and cold conditions in the U.S., but the overall seasonal temperature was near average.

  • The winter season got off to a late start in much of the country. December was the 11th warmest such month on record (based on revised data), and spring-like temperatures covered much of the eastern half of the nation during the first half of January.

  • The warmer-than-average seasonal temperatures in the more heavily populated regions of the Midwest and East helped reduce residential energy needs for the nation as a whole for the winter season. Using NOAA's Residential Energy Demand Temperature Index (REDTI), it was determined that the nation's residential energy demand was approximately 3 percent lower than what would have occurred under average climate conditions for the season.

  • Seasonal energy demand would have been lower if not for February's colder temperatures. For the month, temperature-related residential energy demand was approximately 6 percent higher than what would have occurred under average climate conditions for February.

  • February was among the third coldest in the 113-year record for the contiguous U.S. Thirty-six states in the eastern two-thirds of the nation were cooler than average, while Texas and the eleven states of the West were near average to warmer than average.

  • Winter season precipitation was above average in the central U.S. from the Upper Midwest to New Mexico, Texas and Louisiana. Drier-than-average conditions stretched from the Deep South to Kentucky, the Mid-Atlantic, and along the Northeast Seaboard states. Much of the West was also drier than average.

  • Through early March, water-year precipitation in Los Angeles was the lowest on record, less than 25% of normal.

  • Several snow storms hit the Plains, Midwest, and Northeast in February. A complex, wide-reaching winter storm moved from the Mid-Mississippi Valley into the Mid-Atlantic and New England February 14 and 15. This storm ranked as a Category 3 event on the Northeast Snowfall Impact Scale (NESIS). The heaviest snow fell in interior regions of the Northeast where amounts over 20 inches were widespread.

  • This event was preceded by a 10-day lake effect storm that dumped more than 100 inches of snow on New York's Tug Hill Plateau. A total of 141 inches was reported at Redfield in Oswego County. Additional information on snowfall during the 2006-2007 winter season is available

  • For February, precipitation was below average in the Southeast, Northeast, and Midwest regions. For the Southern Region, the 9th driest February on record followed two wetter-than-average months.

For information on local temperature and precipitation records during the month of February, please visit NCDC's Extremes page.

  • Across the United States, extreme drought conditions were observed in areas of Wyoming and Nebraska, as well as northern Minnesota and parts of Texas. Exceptional drought was limited to areas of south Texas. For more information on drought during February, please visit the U.S. Drought page.

  • El Niño-Southern Oscillation (ENSO) conditions have transitioned from ENSO-warm phase to ENSO-neutral by the end of February. Current forecasts indicate that a transition from ENSO-neutral conditions to La Niña could occur over the next 3 months. For additional information on ENSO conditions, please visit the NCDC ENSO Monitoring page and the latest NOAA ENSO Advisory.
