NWS National Radar
NOAA · Live national mosaicNational radar composite from 160+ NEXRAD sites, updated every 5 minutes, with storm-based warnings overlaid.
Ground-based scanning — precipitation mosaics, NEXRAD products, the storm-reports ledger, plus the lightning, fire, and aviation tools that pair with active weather. Satellite imagery is on its own page.
National radar composite from 160+ NEXRAD sites, updated every 5 minutes, with storm-based warnings overlaid.
NSSL's mosaic that blends NEXRAD with satellite, lightning, and surface observations — higher resolution than NWS radar.
The academic radar viewer forecasters cut their teeth on — individual sites, mosaics, legacy display, every product.
Preliminary storm reports from SPC — tornado touchdowns, hail, wind damage as they're called in.
Real-time global lightning from the Blitzortung volunteer network — 1,000+ stations, updated in under 30 seconds.
Real-time lightning flashes detected from space by GOES, overlaid on visible and IR imagery for CONUS and the ocean basins.
HRRR model with fire-and-smoke component — transport, surface concentrations, and optical depth to 48 hours at 3 km.
National Interagency Fire Center's operational portal — active fires, perimeters, evacuations, fire-weather outlooks.
Real-time US air quality — PM2.5, ozone, AQI by location, plus plume forecasts during fire events. EPA + NOAA.
NWS fire-weather portal — Red Flag Warnings, Fire Weather Watches, spot forecasts, and fuel moisture conditions.
NOAA's Aviation Weather Center — radar, satellite, METARs, TAFs, prog charts, turbulence, icing, and PIREPs in one map.
Graphical AIRMETs — moderate icing, turbulence, IFR ceilings, mountain obscuration, and surface winds.
SIGMETs — severe turbulence, severe icing, volcanic ash, widespread dust, and thunderstorms. The advisory that reroutes flights.
Graphical Turbulence Guidance — 3D forecasts of clear-air, mountain-wave, and convective turbulence to 45,000 ft.
Radar products from the National Weather Service, NOAA National Severe Storms Lab, the Storm Prediction Center, and College of DuPage (academic). Lightning from Blitzortung (crowd-sourced) and NOAA GOES GLM. Fire and air-quality data from the NOAA Earth System Research Lab, National Interagency Fire Center, EPA, and NWS Fire Weather. Aviation weather from NOAA's Aviation Weather Center. Geostationary sector imagery and research-grade satellite tools live on the Satellites page.
