Oklahoma City typically averages 8″ of snow each winter. In December of 1987 and again in January of 1988, however, there were snowstorms that each saw 12″ of snow. Gary thought the second storm was so similar to the first that they must be related. This realization was the inception of the Lezak Recurring Cycle, or LRC.

After almost 30 years of analysis, our knowledge of this regularly cycling pattern is a huge advantage over traditional, flawed weather forecast systems. We are now using automated forecasts and our meteorological expertise to help your team mitigate loss and maximize profit.

We provide the best, most accurate weather forecast, including highs, lows, HDDs, CDDs, GDDs, and much more. Gary Lezak’s video updates will bring the information to life.

Super Bowl XLVII

Event Date: February 2, 2014
Forecast issued: January 6, 2014

When the NFL announced that Super Bowl XLVIII would be played in an open-air stadium in East Rutherford, New Jersey, forecasters predicted that it would be snowed out. Weather2020 maintained the February 2 game would see temperatures in the 50s and no snow. The game never saw a flake of snow!

Major Storm in the South

Event date: January 27, 2014
Forecast issued: December 12, 2013

A major winter storm blew through the southern United States in late January, bringing major activity in the South to a sudden halt. Weather2020 issued a weather alert more than six weeks prior, calling for a major winter storm and arctic blast.

Masters Tournament

Event date: April 7-13, 2014
Forecast issued: February 10, 2014

More than 50 days prior to the tournament, Weather2020 predicted the Augusta, Georgia area would see rain in the early parts of the weekday practice rounds with nice weather moving in by the weekend tournament. Storms closed the tournament for the first time in 11 years Monday, but the rest of the tournament took place without weather problems.

“Weather2020 was vital in the planning of one of my client’s biggest events of the year on May 16. I started consulting Gary’s long-range forecasts eight weeks out. When I saw possible SNOW on this date, I consulted my client and moved the event one week later. Low and behold, snow fell in Chicago on May 16!”

Hillary P., Chicago

“It’s really amazing how easy it is, even for a non-meteorologist like me, to see cycles in weather patterns. The ability to forecast weeks or months in advance, particularly major storm events, has all sorts of practical applications. ”

Charles Spencer, Ph.D., Adjunct Professor of Geosciences, University of Missouri-Kansas City

“Our family had our annual Florida vacation scheduled nearly eight months in advance. When Weather2020 started to forecast a major cold front with rain and storms during our scheduled dates, we decided to postpone our trip one week later. We’re so happy we did! The original dates ended up being extremely wet and rainy. The week we were in Florida had warm weather and sunny skies! The small fees we were assessed for changing our trip plans were minuscule compared to the disappointment we would have felt if we had spent an entire week in Florida with chilly weather, rain, and storms! ”

Stacy B., Oklahoma
