A Greenland block is now developing which digs cold air into the eastern USA.
After the mild winter we just suffered through, when forecasters were mostly in agreement on a brutal winter 2011-2012, a warm winter was caused by the lack of a Greenland blocking high pressure, a positive arctic oscillation, an abnormally cold Stratosphere and many other exceptional issues.
Forecasters are in discussion of a much more seasonable winter 2012-2013 with more East Coast storms than normal.
So we could see snow and cold starting in November because when Earth comes out of a La Nina it can feature a cold and/or very snowy winter the coming winter or the next. We can only hope for that setup or worse like what happened for the winter of 1976-77 and 1903-04, two of the coldest winters ever. A moderate El Nino pattern is developing which could cause storms to come in through California and cross the southern states on a strong subtropical jet stream which is a pattern that could bring some good winter to the whole country. We need a negative arctic oscillation (very cold air moving south) for storms to move up the East coast with cold air injected into them for a supercharged winter with abundant cold and moisture.
Due to the warm temperatures east of the Rockies last season, we had a heating season that was in two parts. The first part was good and the second part was very, very bad. Everything in the heating business was fairly normal into December because people were remembering the past few bad winters.
So far forecasts are showing cold and snow in the Midwest and Northeast:
