Neutral conditions continue across the equatorial Pacific Ocean continued for December and will likely continue for the spring of 2013. From the Climate Prediction Center (CPC) “a sudden stratospheric warming (SSW) began January 6 and is expected to continue into February. SSW has been associated with subsequent tropospheric anomalies and changes to the temperature pattern over North America, including below normal temperatures in the eastern U.S. the temperature outlook for February 2013 indicates elevated probabilities of below normal temperatures from the northern Rockies across the northern plains into the western great lakes region and upper Mississippi Valley.”
We have mixed temperature and precipitation forecasts for the coming months. It looks like the current arctic outbreaks West Michigan is about to experience may continue into February leading to a below average temperature outlook. The precipitation forecast is less clear so the Climate Prediction Center (CPC) outlook is for an equal chance of above, below, and near normal precipitation conditions for the Great Lakes.
For the February–April outlook the Climate Prediction Center (CPC) calls for an equal chance of above, below, and near normal temperature conditions for the western Great Lakes but above normal precipitation.
