Built for snow removal contractors, schools and facilities - Better ice forecasts: AI-corrected freezing rain amounts for the Gulf Coast and Midwest over the next 2 days, ice accumulation estimates out to 7.5 days, and better rain/snow/ice calls across the US. - Truer thunderstorm chances: The daily thunderstorm chance reflects the real odds of thunder that day, and thunder, rain chances and weather icons always agree. - Faster updates: Each forecast update reaches customers sooner. Bug Fixes - Extended range no longer shows 87 mph gusts or flat highs and lows - Rain and snow totals no longer drop from one hour to the next - Heat index uses the full NWS formula, and the day/night flag is no longer an hour off - Notifications: no more false hottest day of the year, odd vs yesterday trends, cloud icons on clearing skies, sunset heat alerts or duplicate digests - Lightning go/no-go no longer sticks after all clear, and the widget and app agree - Paying iOS customers no longer see Validation failed, and the backend going down no longer revokes premium
