Joel Gratz

Founding Meteorologist & CEO

Joel really (really) likes three things: Weather, snow, and skiing.

After a childhood spent ski racing and teaching skiing at Shawnee Mountain in Pennsylvania, Joel attended Penn State to study meteorology and to continue ski racing.

After graduating at the top of his meteorology class in 2003, Joel moved to Boulder, Colorado to enjoy the good life in Colorado and to attend graduate school. While earning a Masters in Environmental Studies and an MBA, Joel realized that forecasting snow in the big mountains of Colorado was very difficult and missed a few incredible powder days due to inaccurate forecasts made by himself and others.

Vowing to not miss another powder day, Joel studied the mountain weather patterns of Colorado and started sharing forecasts in 2007 via an email list called Colorado Powder Forecast.

In 2009, Joel moved his forecasts online to, and this site became known as the go-to source for snow forecasts in Colorado. In 2010, Joel left his full-time employer to start a business around forecasting weather and skiing powder. And during 2011, a fortuitous thing happened and Joel met another meteorologist and programmer named Andrew Murray. The two teamed up to create and the rest is (snowy) history.

Joel still lives in beautiful Boulder, Colorado, home to an incredible number of supportive entrepreneurs. You can find Joel skiing deep powder both in bounds and in the backcountry, as well as hiking, biking, and chasing thunderstorms in the summer months.
