Inevitable Episode 66

Why This Winter’s Snowpack Collapsed with Joel Gratz of OpenSnow

Recorded on April 9, 2026 Published April 28, 2026

Joel Gratz is Founding Meteorologist and CEO of OpenSnow, a weather platform used by hundreds of thousands of skiers, snowboarders, and outdoor enthusiasts to track snow conditions and forecast powder days. What started as a text thread among friends has grown into a profitable, bootstrapped business combining expert forecasting, data science, and increasingly AI-driven weather models.

In this episode of Inevitable, Gratz breaks down one of the worst Western snowpack seasons on record and why he believes it’s not as simple as blaming climate change.

The conversation explores the role of atmospheric variability versus long-term warming trends, why temperature matters more than precipitation for snowpack, and how mountain weather forecasting differs from traditional forecasts.

Finally, Gratz explains why emotional connection, not just accuracy, is what makes niche weather businesses work.
