News - All-new Flash app: A complete redesign with a live animated sky, swipeable charts, official warnings, custom forecasts for user events and holidays, nine color themes and better radar. The most revolutionary FLASH App update to date. New Features - Updated theme: Modern, glassy appearance now appears through the entire app. - New current conditions and forecast section. Dynamic hourly and daily forecast cards with detailed ranges and charts. - Custom Event and holiday forecasts: Save a game, cookout or trip (or a whole season) and get the forecast ahead of it and lightning alerts during it. Holiday forecasts are free for everyone. - Future radar by precipitation type: A new high resolution future radar that predicts precipitation by type (rain, snow, sleet, freezing rain) and intensity. - Weather history and normals: 50 years of history for every customer site, plus normals and records for every date. "On this date" and forecast trends are now free for every user in the WCC and app. Performance Improvements - More accurate everywhere: Outside the US, next-day temperatures are about 28% more accurate than our previous global forecast in testing, with big gains for dew point, wind and gusts too. - Snow and winter: Our AI snowfall correction was about 15% more accurate than the National Weather Service for next-day snow over the last two winters, and the snow level is now in the API and on the maps. - The next few hours: Rain and thunderstorm chances for the next few hours are now corrected from live radar, lightning and satellite data, leading to more accurate short range forecasts. - Lightning safety: Pick Safest, Standard or Faster all clears, opt in to a stricter Warning (beta) for fewer false alarms, and see improved consistency in all clear status across the app, WCC, and widgets. - Clearer alerts: Alerts say how confident we are, lead with the hazard and only flag wind that's unusual for the local area. Bug Fixes - General fixes and improvements to forecast accuracy since the last release.
