I am expecting a snowy winter for the Great Lakes. Based on observations on the stratosphere, the lower strat. is at normal values for this time of year, indicating the possibility of a negative NAO. With the negative NAO, the jet stream buckles and sends frigid air south that typically ignites the lake effet snow machine for those in blue. An El Nino typically does enhance a negative NAO, and this, combined with the favorable stratosphere values, should bring more than a few shots of arctic air southward into the Great Lakes region. Add a couple of degrees above average that the Lakes are currently at, and this winter could be very white.
THIS ENDS THE 2012-2013 REGIONAL WINTER FORECASTS.
