GrayCloud Weather

GrayCloud runs its own forecast engine on National Weather Service and NOAA data to give you minute-by-minute rain prediction for your exact address. Forecasts, radar, and severe alerts work worldwide, with the deepest data across the US, Canada, and EU.

Features:

- Minute-by-minute rain prediction: when it starts, how hard it falls, and when it stops

- Current conditions, hour by hour, and a 10-day forecast

- A home page you arrange yourself: reorder or hide any card, pick your buttons and theme

- Save as many locations as you want and swipe between them

- Live severe weather alerts from the NWS in the US and official agencies worldwide, matched to the storm polygon, not your whole county

- Twelve data cards to tap into: Rain, Soil and drought, Wind, NWS, Clouds, Air quality, UV index, Dew point, Astronomy, Climate, Records, and Tides

- Official NWS products: Area Forecast Discussion, the point forecast, and the SPC storm outlook, plus your day one severe risk

- Rainfall totals for 24 hours, 7 days, 30 days, month to date, and year to date, checked against official rain gauges

- Rain calendar: every rain day on a monthly heat map, tap a day for hour by hour, with history back to 2020 and snow totals alongside rain

- Weekly rain targets, and drought status from the U.S. Drought Monitor, soil moisture, and state and national drought maps

- Time Machine: scrub back to any past day and see what actually happened

- Climate normals, on this day and all-time station records, and your own personal records

- Sun arc, twilight, day length, moon phase on a 3D moon, meteor showers, and eclipse timing

- Real time radar with lightning and many map overlays:

- GPU-rendered high-resolution radar, smooth at any zoom

- Observed MRMS radar and a live nowcast on one timeline, scrubbable two hours back and into the near future

- Tap anywhere for a forecast at that point, or share an animated radar loop

- Notifications you control, per location:

- Rain starting at light, default, or heavy sensitivity, plus rain ending and intensifying

- Severe weather, with a floor of all, moderate, severe, or extreme

- Morning briefing and tomorrow's forecast, at times you pick

- Freeze, heat wave, wind gusts, UV index, daily rain, and daily snow, at thresholds you set

- Sky and seasons: full moon, new moon, the first day of each season, meteor showers, and eclipses

- NWS report updates when the discussion, forecast, or outlook changes
