If you regularly ski or snowboard at a Tahoe ski resort, this is one topic that is always intriguing – what’s the weather going to be?
Skiers and riders are definitely “weather watchers.” A desire to know the conditions before heading to the Tahoe region is vitally important to the masses who descend on the ski resorts – especially when it’s a weekend destination.
Tahoe Ski World does its best during the ski season to advise skiers and riders on conditions throughout the Tahoe region. Is it going to snow, and if so, how much? What will temperatures be? Are there avalanche dangers? Is wind going to be a factor? Also important – how are the road conditions?
For many years, our Tahoe-focused website has regularly relied on the excellent weather forecasting by OpenSnow to keep its subscribers and casual users aware of weather conditions at Tahoe ski resorts.
In our opinion, the Tahoe region forecasting of OpenSnow’s Bryan Allegretto is extremely detailed and reliably accurate! With years of experience living and working in the Tahoe region, Allegretto is a Tahoe forecaster that’s definitely worth following.

WHAT IS OPENSNOW: A trusted source for accurate U.S. weather forecasts, snow reports, and AI-powered weather maps, OpenSnow is comprised of an adventure-focused group of meteorologists.
OpenSnow has been operating for more than a decade while maintaining one of its primary goals – making it easy for skiers and riders to find their next powder day.
The website is not just Tahoe focused. It reaches millions of people worldwide and still regularly obsesses about making its forecast more accurate, and creating new features to make finding the ideal conditions even easier.
While Tahoe Ski World uses OpenSnow’s services primarily for the Tahoe region, the weather website has large tentacles. OpenSnow provides snow and mountain weather forecasts for ski resorts and mountain regions in the U.S., Canada, Europe, Scandinavia, Australia, and New Zealand.
WHAT’S NEW THIS SKI SEASON? OpenSnow is launching a first-of-their-kind new tools for the 2025-26 ski season that leverage AI machine learning to transform how everyone plans around weather.
One of the most consequential developments is PEAKS, a robust AI-powered weather forecasting system that is up to 50% more accurate than standard forecasting models in mountainous terrain.
Updated every 30-60 minutes as new model data is available, users can track precipitation, temperature, and wind forecasts that are adjusted, based on each storm’s strength and trajectory. The system leverages OpenSnow’s proprietary forecasting formula to fine-tune 11 weather models used by their professional forecasters and more accurately predict weather conditions.
“Our focus has always been to continually improve forecasting accuracy and make it available and easy for everyone to make safer, smarter decisions,” Allegretto said. “These new AI-powered features are a significant step forward, helping simplify complex weather models so anyone can understand weather risks and timing with greater detail and accuracy.”
Additional forecasting tools OpenSnow will introduce this year reveal even more details behind each forecast:
PEAKS Avy: An AI-powered avalanche forecast model, PEAKS Avy will produce an overall danger rating and identify potential avalanche “problems” for eight aspects and three elevations per avalanche forecast center “zone.” This model, informed by the work of human avalanche forecasters, has automated the forecasting process to enable updates multiple times per day.
PEAKS Snow: Want to know when the snow is expected to turn from powder to chalky or grippy conditions? PEAKS Snow was designed to convert complex weather and snow data into an easy-to-understand graphical and textual description with nuanced snow quality details that skiers and riders may experience.
15-Day Forecasts: Generated from OpenSnow’s new PEAKS weather forecasting system, detailed, multi-model 15-day weather forecasts for any location and elevation on Earth now allow OpenSnow users to compare forecasts for their favorite ski resorts, backcountry locations, camping destinations, or current location.
Compared to other weather predictions, OpenSnow now offers a look into five more days than the average forecast.
Forecast Range: Offering a 15-day outlook, new Forecast Range Graphs provide a multi-model comparison of every global and regional weather model in OpenSnow, generating a clear view into whether forecast models are in tight agreement (higher confidence) or show a wider spread (lower confidence).
Power users can also use the graphs to isolate favored models to dig further into scenario details.
Forecast Global Radar: Providing a worldwide, 15-day outlook, Forecast Global Radar explores precipitation type forecasts in 2D or 3D for any location on Earth.
Powered by the ECMWF (European) model, it is updated every 12 hours with the latest available forecast data and can be used to improve trip planning, event logistics, and commute readiness over land and water.
Forecast Snowfall Maps: For any location in the U.S. and southern Canada listed on OpenSnow, users can visualize expected snow totals in 2D or 3D for the upcoming 6, 12, and 24 hours, plus total snowfall over the next 10 days with Forecast Snowfall Maps.
These maps are incredibly useful for those interested in timing storm arrivals to know where to find the deepest powder day turns, when to avoid hazardous driving conditions, and to see which ski areas are favored to receive the biggest snow totals. The high-granularity timing can also help resorts optimize their operations.
AI Personal Forecaster: An AI-powered predictive description of the weather and snow that a skier or rider will likely experience on the mountain, AI Personal Forecaster leverages OpenSnow’s proprietary weather data to write detailed forecasts winter sports enthusiasts will want to read.
“In the development of PEAKS, we had the system go back through 40 years of data to look for bias and errors in past forecasts so that it can make more accurate predictions in the future. We have found that using the AI model to make changes has resulted in forecasts being up to 50% more accurate,” Allegretto said.
A FINAL NOTE: These AI-enhanced weather forecasting features, plus OpenSnow’s expert forecasts, are or will soon be available on the OpenSnow App that can be downloaded on the Apple App Store or Google Play.
