Weather Radar

Data Sources

Local Weather Radar displays weather information from established, publicly available meteorological data providers.

Radar Imagery

Radar maps on this site come from RainViewer, which aggregates radar data from national weather services around the world. In the United States, this data originates from the NEXRAD (Next-Generation Radar) network operated by the National Weather Service (NWS), a division of NOAA.

Radar imagery updates approximately every 10 minutes and shows precipitation intensity and cloud cover across each city's coverage area.

Weather Forecasts

Current conditions, hourly forecasts, and 7-day forecasts are provided by Open-Meteo, an open-source weather API. Open-Meteo sources its data from multiple national meteorological agencies, including:

NOAA / NWS (United States) — GFS, HRRR, and NAM models
DWD (Germany) — ICON model
Environment and Climate Change Canada — GEM model
Météo-France — ARPEGE and AROME models

Update Frequency

Data Type	Source	Update Interval
Radar imagery	RainViewer (NEXRAD)	~10 minutes
Current conditions	Open-Meteo	~30 minutes
Hourly forecast	Open-Meteo	~1 hour
7-day forecast	Open-Meteo	~6 hours

Accuracy

Weather data accuracy depends on the upstream models and radar networks. Radar imagery is observational data (what is actually happening), while forecasts are model predictions that become less precise further into the future. For official warnings and emergency information, always refer to your local National Weather Service office at weather.gov.

No Proprietary Data
