Forecasting Snow in Colorado Next Humanist Science Sunday Program Oct. 4

The next Central Colorado Humanist Science Sunday presentation on Oct. 4 will examine the science of forecasting snowfall in Colorado this winter.

The program, How to Forecast Snow in the Mountains of Colorado and this winter’s snow outlook will be presented by meteorologist Joel Gratz.
Gratz is the founding meteorologist and Colorado forecaster for, a website and mobile app that provides snow forecasts and travel advice to over 2.5 million skiers and snowboarders annually. 

Gratz will look at multiple forecasts for this winter and discuss if we should trust them. The program will dig deep into weather models and snow reporting data to understand how this information can be utilized to forecast snow in Colorado’s high mountains and to find the best powder.

Gratz graduated from Penn State with a degree in meteorology and then earned his MS and MBA from the University of Colorado. As a die-hard skier and powder seeker, he spent years studying local weather patterns and made his first public snow forecast in 2007 to an email list of 38 people. 
In 2011, Joel left his day job to work on full time. The site has grown since then and now includes skiing weather forecasters across the country.

Gratz will also present information on the Open Summit app, which has forecasts for specific peaks for summer hikers.

The program is viewable on ZOOM beginning promptly at 10 a.m. Oct. 4.
