DES MOINES, IWOA—A rollercoaster of dry weather, then wet with flooding, followed by a return to dryness for northwest counties by the end of 2014 resulted with a statewide average rainfall of 4.3 inches above normal for the year.
Temperatures were up and down as well. February, July and November 2014 ranked among the top ten coldest for those months in the historical record, while December was the only month of the year significantly above normal in average temperature.
Shallow groundwater improved to normal conditions statewide by the end of June. Yet northwest Iowa was left in abnormally dry conditions the end December, hoping for rainfall in the coming spring to recharge alluvial aquifers to prevent drought conditions from worsening.
