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.

During late winter, Texas, Oklahoma, and Kansas received sorely needed rain which helped reduce short-term impacts, like wildfire and dry topsoil. But 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.

On any given day or any given month, somebody somewhere experiences colder-than-average temperature, even though the globe as a whole is warmer than average. We know this through climate monitoring, which entails measuring temperature on land and across the ocean.
Low pressure differences between the Arctic and mid-latitutde regions define the negative phase of the Arctic Oscillation and often bring cold temperature to North America, Europe, or northern Asia. Much colder-than-average temperature during March and a strongly negative Arctic Oscillation Index reminded people in the United States how important this index is to our own climate conditions. A year ago, the positive phase of the oscillation was in play during March, and conversely warmer-than-average temperature blanketed the United States.

The big story for the upcoming spring is the likelihood that drought will continue across large parts of the south-central and southwestern United States, and even expand into California and eastern Texas. Some of these areas have been experiencing drought for more than a year, and the latest 3-month outlook from the Climate Prediction Center offers little hope for relief.

The Story for Spring: Drought Relief Not Likely

NOAA’s Climate Prediction Center released its Spring Outlook on March 21. The big story for the upcoming spring? Relief for many drought-stricken areas of the United States is not likely.
In Watching for El Niño and La Niña, NOAA Adapts to Global Warming
February 5, 2013 Rebecca Lindsey
As the whole ocean gets warmer, NOAA scientists must redefine what they consider “average” temperature in the central tropical Pacific, where they keep watch for El Niño and La Niña.
