Gary Lezak explains this forecasting theory - Lezak's Recurring Cycle

KANSAS CITY, Missouri - The Lezak's Recurring Cycle (LRC) is a theory developed by Gary
Lezak. Gary noticed back in the 1980s that storm systems seemed to
have similar characteristics unique to that year.
Quite simply a storm in February looked very similar to one that
had occurred earlier in that season, say in December. As the years
went by Gary started paying closer attention to the weather
patterns and he came up with the LRC.
The LRC (Lezak's
A unique weather pattern sets up every autumn between October
1st and November 10th
"Long term" longwave troughs and ridges become established
over the northern hemisphere
The pattern cycles and repeats over and over again until it
slowly weakens and falls apart late in the summer before a new
pattern sets up in the fall
It isn’t just one storm that repeats. It is
the entire weather pattern that is cycling. We believe that a good
weather forecaster can use knowledge of the LRC and make accurate
weather forecasts both short and long range.
Once we figure out the cycle and the weather
pattern we can project weeks to months ahead and make these
accurate forecasts. Last winter (2009-2010 season) we made a
prediction on December 3rd that there was a high likelihood of a
major snowstorm around Christmas.
Gary used his knowledge of the LRC and made this
forecast based on the weather pattern that had set up in October
and November. On Christmas Eve a major snowstorm and blizzard
tracked from Oklahoma City to Kansas City. An accurate forecast
made three weeks out, which is unheard of in weather forecasting,
but not any more.
The new LRC has set up for this winter and our weather team has
spent the past few weeks analyzing the data and we will be making
our winter forecast soon. As we move into December our weather
forecasts can get more specific, so read the
