NOAA expects Iowa winter to be unpredictable

The National Oceanic and Atmospheric Administration (NOAA) released its predictions for winter weather on Thursday.

Last year the midwest experienced the warmest winter on record in 121 years, but this year NOAA says that Iowans can expect a grab bag of both warm and cold temperatures. Both temperature and precipitation are expected to hover around average from December through February for much of the state, except for the northern most part of the state, which is expected to be colder than usual.

NOAA also expects a weak La Niña this year. La Niña is characterized by particularly cold ocean temperatures in the Equatorial Pacific, and often affects weather trends in the United States. Variances in La Niña’s strength and duration from year to year can make forecasting winter temperatures difficult. Mike Halpert is deputy director with NOAA’s Climate Prediction Center, he said, “Because there is still some uncertainly about when La Niña will develop and persist through the winter, probabilities on the maps this year are fairly conservative.”

Winter 2015-2016 was the wettest Iowa winter on record in 101 years. Other parts of the Midwest and the Western U.S. are predicted to receive high amounts precipitation this year, with Idaho, North Dakota and the Ohio Valley all among those that will be affected. Unusually cool temperatures are on the forecast from Eastern Montana through Wisconsin.

In short, NOAA expects wetter and colder than usual temperatures for the far northern Midwest and warmer with drier winter conditions for the Southern U.S., and most of Iowa falls somewhere in the middle. Much like most winters, Iowans should prepare for anything.
