MET Norway and NWS forecasts
MET Norway forecasts are provided by the Norwegian Meteorological Institute under CC BY 4.0. Forecast data is adapted for display. NWS forecasts are provided by the National Weather Service for supported U.S. locations.
Apple Weather (WeatherKit)
When Apple Weather is selected as the forecast provider, current conditions and hourly and daily forecasts are provided by Apple Weather through WeatherKit. Review Apple Weather data sources and legal attribution. If Apple Weather is unavailable, forecasts may be provided by Visual Crossing instead.
Radar coverage
Locations within the contiguous-U.S. source area use our updated radar. Locations outside that coverage, including Alaska, Hawaii and U.S. territories, open the previous Weather.com radar with its satellite and precipitation layers. The map center determines coverage: zooming out keeps the U.S. radar, while panning its center outside coverage opens the previous radar.
The updated radar starts at the latest observation, with history to the left and the full available forecast to the right. Its forecast extends to the end of the 18-hour HRRR model run; the remaining time depends on the run's age. Press Play to animate, or Now to return to the latest observation.
The previous radar uses its own Layers and Past/Future controls. Its available forecast depends on the provider; our September 2026 checks in Seoul and London reached more than six hours ahead. This is not a guarantee for every location or future provider update.
Forecast frames predict precipitation; a longer timeline does not by itself mean greater accuracy. Local radar gaps, terrain blockage and provider outages can affect the display. In the updated radar, Earth is archived basemap imagery.

LibreWXR data
Blended and rendered by LibreWXR. Data credits below follow its source documentation and usage terms. Sources available in a particular frame depend on the provider's live feed.

LibreWXR converts, blends and interpolates these sources into precipitation tiles. Most data uses attribution licenses such as CC BY 4.0 or the linked government licenses; Italian radar derivatives use CC BY-SA 4.0. See the provider's source documentation for each dataset's terms.
Precipitation type
Worldwide snow colors use LibreWXR's model-based snow classification. U.S. forecast frames use IEM HRRR REFP when the matching model run is available: rain, snow, freezing rain and ice/sleet. The rain, snow, ice and freezing-rain legend stays fixed throughout playback. Observed U.S. reflectivity does not identify precipitation type; it uses the rain color scale for all echoes, with that limitation noted in the frame status. If type data is unavailable, the regular reflectivity forecast remains available.
Basemap and display
U.S. imagery: USGS The National Map. Worldwide imagery: NASA Blue Marble via NASA GIBS. Worldwide imagery has less street-level detail than the U.S. basemap.
Roads, boundaries and place names: OpenFreeMap, OpenMapTiles, and © OpenStreetMap contributors. The Roads background is a locally authored map style using the same OpenFreeMap vector data. Vector labels are drawn above precipitation to stay readable when zooming. If vector rendering is unavailable, basic USGS or NASA GIBS / OpenStreetMap labels are used.
U.S. observed radar and fallback forecasts use the same green-to-yellow/orange rain scale as IEM's precipitation-type forecasts. Snow, ice and freezing rain keep their distinct forecast colors. Worldwide tiles use LibreWXR's TWC palette with snow classification enabled. These are display treatments, not additional weather detail. Forecast grids and satellite/model estimates have lower resolution than some ground radar observations. Opacity is adjustable in Layers; the default is 75%. Display smoothing is deliberately limited to retain precipitation detail. Weak echoes can still appear faint.
