Drew Lerner at World Weather, Inc. makes an interesting analogy between U.S. weather this spring, and that of 1968. Both this year and 1968 involved recovery from peak solar activity (sunspots) and neutral ENSO (El Niño/Southern Oscillation) conditions.  He looked at seven previous solar maximum years and found that each involved wetter weather in the lower Midwest, Southern Plains, Delta and the Tennessee River Basin during the spring season.
