Forecasters expect a warm winter
October 28, 2009

After last year's brutal cold, Midwesterners might be happy to hear that NOAA's 2009 winter weather outlook predicts a very good chance of warmer-than-normal weather for our part of the country this winter. El Nino patterns are expected to warm things a bit, and other factors and cycles point in the direction of warmer weather here, too. Seasonal weather patterns have several effects on the water industry, including the availability of time and conditions for winter construction at water and wastewater treatment plants, as well as a significant ongoing effect at wastewater lagoons, where temperature and density inversions arriving in the spring and fall can cause unintended instability.
