Until a warmer-than-average May, spring 2013 was reluctant to arrive for a majority of the United States. The country’s overall average spring temperature was the coolest since 1996, and it was also the first season in the contiguous United States that the seasonal temperature was below average since the winter of 2010–2011. In addition to cool temperatures, spring brought both wet and dry precipitation extremes to areas across the nation.

Tampa Bay Water Supply Manager Allison Adams knows water is precious for the millions of residents who rely on the water agency for drinking water and recreation, and for the region’s natural ecosystems, including wetlands and lakes. Adams and colleagues discuss how their evolving water management approach allows them to balance diverse water needs in the face of often unpredictable water sources and cycles.

Tampa Bay Water provides safe, potable drinking water to 2.3 million people in the Tampa Bay region. But future availability of surface water can be hard to predict, and drought is a recurring challenge there. The water utility managers are increasingly using seasonal climate forecasts to track climate variability, which helps them better plan their water supply and reduce their vulnerability to seasonal climate impacts.

In brief. This map shows drought status across the contiguous United States on June 4, 2013. Colors on the map indicate areas that are abnormally dry (yellow) or experiencing some level of drought (ta ...

Rain and snow across the contiguous United States during April 2013.

NOAA’s Climate Prediction Center (CPC) has issued its 2013 Atlantic hurricane seasonal outlook. In this video, Gerry Bell, a NOAA CPC meteorologist, explains that as of May 23, 2013, the outlook favors an above-normal Atlantic hurricane season from June 1 through November 30.

Spring 2013 has brought something fairly unusual in recent years—colder-than-average temperature for the nation as a whole.

The average global temperature for April 2013 was the 13th highest on record for April at 57.64° Fahrenheit. It also marked the 37th consecutive April and 339th consecutive month (more than 28 years) with a global temperature above the 20th century average. The last below-average April temperature was April 1976 and the last below-average temperature for any month was February 1985.

During late winter, Texas, Oklahoma, and Kansas received sorely needed rain which helped reduce short-term impacts, like wildfire and dry topsoil. But as Deke Arndt explains, it has taken months to develop deep and severe drought in the region, and a few wet weeks won't erase that situation. It can take months of ideal conditions to bring soil, rivers, and vegetation back to health.

Spring 2013 has brought something fairly unusual in recent years: colder-than-average temperature for the nation as a whole. NOAA's Deke Arndt talks about how spring temperatures in three U.S. climate divisions compare to the local long-term trend.
