U.S. climate highlights - March
  • Most of the eastern U.S. was cooler than average during March, with the exception of New England, which was slightly warmer than average. Eleven states in the Ohio Valley, along the Gulf Coast, and in the Southeast had March temperatures that were among their ten coolest. Alabama, Florida, Georgia, North Carolina, and South Carolina had March 2013 temperatures that were cooler than January 2013.
  • Temperatures were above average for parts of the West. Arizona, California, and Nevada each had March temperatures ranking among their ten warmest. Above-average temperatures were also observed in Washington, Oregon, Idaho, Utah, and New Mexico.
  • A large area of the contiguous U.S. had near- to below- average precipitation during March. The West, Southern Plains, Gulf Coast, and Northeast were particularly dry. Louisiana had its fourth driest March and Wyoming had its fifth driest. Minnesota was the only state with above-average March precipitation.
  • Several storms brought late-season snowfall to the eastern two-thirds of the country. According to data from the Rutgers Global Snow Lab, the March snow cover extent for the contiguous U.S. was the 10th largest in the 47-year period of record. However, snowpack, an important water resource in the West, was below-normal in the Sierra Nevada Mountains as well as the Central and Southern Rockies.
  • According to the April 2 U.S. Drought Monitor report, 51.9 percent of the contiguous U.S. was experiencing moderate-to-exceptional drought, smaller than the 54.2 percent at the end of February, but significantly higher than 36.8 percent at the beginning of April last year. Drought conditions improved in parts of the Southeast, as well as the eastern edge of the core drought areas in the Central and Southern Plains due to increased precipitation over the past three to six months. Drought remained entrenched across the rest of the Great Plains and interior western states.
