I always say that a cold winter will be followed by a hot summer.  If you average the temperature through the year, that average will be very little different from year to year.  I recall my Dad talking about the year 1936, which was the coldest winter he recalled in his lifetime, and 1936 was the hottest summer he recalled in his lifetime.  We in the northern cornbelt lacked the hot summer in 2009, to produce good corn.  Hopefully 2010 will be a hotter summer.
