Cooler than average temperatures are expected to persist through the remainder of the spring season in South Dakota, according to National Oceanic and Atmospheric Administration's Climate Prediction Center. The most recent update was released March 20, 2014, which includes projections for temperature, precipitation and drought for the spring and early summer. Most of the state will likely have below average temperatures in April, and could linger through May and beyond for the state's northern counties. During the last month, several climate forecasts have shown that El Nino is becoming more likely for the 2014 growing season. This can mean wetter and cooler for eastern, especially southeastern, South Dakota for May through September.
