StormNet vs StationDeck

StormNet is optimized to provide the most accurate severe weather forecast with NEXRAD, Super-Res Radar. StormNet is completely free, with no ads. Trained on decades of severe weather events, StormNet analyzes high-resolution radar, satellites, ground-based sensors, and weather forecast models in real-time to find complex patterns that lead to severe weather. The model updates every 2 minutes to provide 14-day forecasts for lightning, hail, damaging thunderstorm winds, and tornadoes. Super-Res Radar is the highest-resolution NEXRAD radar data available from 159 stations across the continental United States. Each radar station updates every 3-4 minutes and measures the intensity of precipitation based on how much energy the radar signal receives back from objects in the atmosphere. Combined, StormNet + Super-Res Radar provides a first-of-its-kind, multiple-component severe weather forecast system for the United States. StormNet Map Overlays • Radar: The highest-resolution radar available for the United States from each radar station. • Radar + Risk: NEXRAD radar, alongside StormNet risk probabilities, for the next 4 hours. • Risk Forecast: The StormNet risk probabilities from real-time to 14 days into the future. StormNet Risk Forecasts • Lightning • Hail • Damaging Winds • Tornado Super-Res (NEXRAD) Radar • Radar Reflectivity • Radar Velocity • Spectrum Width National Weather Service Warnings • Tornado • Severe Thunderstorm • Snow Squall • Flash Flood StormNet vs. National Weather Service The National Weather Service, the Storm Prediction Center, and other government agencies are the official sources for watches, warnings, and severe weather information. StormNet should serve as a trusted and automated guide for severe weather risk, but StormNet should not be treated as an official source. StormNet vs. Traditional Weather Models Existing weather forecast models are incredible feats of engineering and predict the ingredients for severe weather, but they are not designed to excel at severe weather forecasting and are not real-time tools. StormNet was trained and optimized to provide severe weather forecasts. StormNet vs. Other Weather Apps Existing weather apps and companies usually pass along official government watches and warnings, and often communicate if lightning or hail is already close by. While these are valuable features, we are not aware of another weather app or company that matches StormNet’s ability to provide real-time updates for lightning, hail, damaging thunderstorm winds, and tornado risk. Powered by OpenSnow In 2011, OpenSnow began predicting snowfall for skiers and snowboarders. OpenSnow has since become a global leader in mountain weather forecasts and expanded to provide forecasts for every type of outdoor activity. Since lightning is a risk to outdoor activities, especially on longer mountain-based adventures, OpenSnow created a weather forecast system that would provide both lightning forecasts to support real-time decisions and multi-day outlooks to support trip planning. Meteorologist Andrew Brady built StormNet to predict the risk of severe weather. OpenSnow acquired his technology in 2024 to help people stay safe and enjoy the outdoors. — Terms & Conditions — StormNet is free and available in the United States.

StationDeck turns a personal weather station into the weather app you actually want — and works even before you own one. Connect an Ecowitt or Ambient Weather station, or pull readings through Home Assistant. Point it at any public Weather Underground station — usually a neighbour's back garden rather than an airport twenty miles away. Don't have a station yet? Start with the nearest official National Weather Service station and add your own hardware later. YOUR DASHBOARD, YOUR ORDER Every card can be reordered or hidden. Temperature, feels-like, dew point, humidity, wind, rain, pressure, solar, UV, indoor conditions — arranged the way you read them, not the way someone else decided. FEELS LIKE, CORRECTED The standard heat index is a shade figure. The National Weather Service notes that direct sun can add as much as 15°F to how hot it actually feels. StationDeck uses your station's own solar sensor to apply that correction, alongside NWS wind chill when it's cold — a number your station's stock feels-like doesn't give you. TRENDS THAT GO SOMEWHERE Tap any reading for its history: 24 hours, 7 days, 30 days or a full year, with high, low and average. Barometric tendency is read out properly — rising, falling, and what that usually means — because a bare pressure number tells you nothing on its own. WIND, READ CORRECTLY Direction on a compass dial rather than a bare number, and a wind rose showing where the wind actually came from over time. Not a line chart, which is meaningless for a value that wraps through north. RADAR AND FORECASTS Animated precipitation radar with adjustable base map, opacity and playback. Official NWS forecasts, daily and hourly, for your station and any other town you care about. Severe weather alerts scoped to your exact coordinates. WEATHER MODELS Compare GFS, ECMWF, ICON, HRRR and five more side by side, as charts or as a map you can scrub through hour by hour. When the models disagree, that spread is the honest measure of confidence — and StationDeck shows it rather than hiding it behind a single number. ALL-TIME RECORDS Hottest, coldest, strongest gust, wettest day and wettest month, each with the date it happened, computed from your station's own history. SENSOR HEALTH Battery voltages become plain language — Good, Fair, Replace Soon — with an estimate of how long is left, learned from the actual drain rate over time. Solar-charged sensors are treated as what they are rather than flagged as failing every night. WIDGETS AND LIVE ACTIVITIES Home Screen widgets with four independently chosen readings, Lock Screen widgets, and a Live Activity that starts on its own when it rains or the wind gets up. ALERTS THAT MATTER High gust, freezing, heavy rain, low sensor battery, and a station that has stopped reporting — plus official NWS severe weather warnings. BUILT THE WAY IT SHOULD BE No account. No analytics. No tracking. No advertising. StationDeck never asks for your location — you tell it where you are. Your API keys stay in the device Keychain and are sent only to the service they belong to. Settings sync through your own iCloud account, which the developer cannot see. Forecasts, alerts and official station observations cover the United States and its territories. Your own station, radar and weather models work anywhere.
