OpenSnow introduces PEAKS 2.0, its most accurate forecasts yet

BOULDER, Colo. – OpenSnow, a trusted source for the most accurate U.S. weather forecasts, snow reports, and weather maps, has launched the newest version of its robust forecast model technology, PEAKS 2.0. The company’s in-house machine learning weather forecast system delivers unprecedented accuracy for mountain weather and snow forecasts for exact locations.

“Conventional weather models take a current state of the atmosphere and simulate how the weather will change over time,” said Andrew Brady, OpenSnow meteorologist and founder of StormNet. “PEAKS 2.0 is inherently different because it uses actual weather stations to learn what is actually occurring on the ground. It employs a sophisticated model that leverages deep learning, weather prediction model emulation, bias correction, and model weighting to provide accurate, hyper-local forecasts that are consistently ranking first across all variables.”

Mountain weather is notoriously difficult to predict because conventional forecasts treat large swaths of terrain uniformly, often missing the complex interplay of peaks, valleys, elevation, and storm behavior. With PEAKS 2.0, OpenSnow’s forecast modeling:

  • Understands how each storm interacts with terrain and elevation specific to mountains
  • Predicts precipitation, temperature, and wind simultaneously
  • Offers clearer, more reliable forecasts so skiers, snowboarders, backcountry travelers, and mountain communities can make smarter and safer decisions

Available in the continental U.S. and limited international locations, testing of PEAKS 2.0 has demonstrated the platform is more accurate than other forecast models, including the National Weather Service and Google’s WeatherNext 3. It more accurately predicts future weather by learning from actual (not modeled) past weather at thousands of stations, and is more detailed because it can “see” valleys, ridges, and slopes, with a resolution of 1.5 miles and adjustments down to a hyper-local 50 feet. PEAKS 2.0 also shows a range of outcomes and extends its high-resolution predictions out to 15 days.

Evaluations across the continental U.S. have demonstrated that PEAKS 2.0 forecasts outperform NOAA’s National Blend of Models (NBM), the National Weather Service (NWS) forecasts, and every individual model evaluated, including the European ECMWF, American GFS, Canadian GDPS, German DWD-ICON, and more.
