Live Doppler Rain Radar — Idaho
The Idaho Rain Radar provides live, high-resolution Doppler reflectivity scans tracking active precipitation, cloud burst intensity, and storm movement across {state} counties. Track real-time rainfall, precipitation movement, and storm reflectivity across Idaho on our live interactive Doppler rain radar map. Data updates every 5 to 10 minutes from NOAA & NWS dual-polarization Doppler stations.
NWS Radar Station Infrastructure (Idaho)
Radar surveillance across Idaho relies on National Weather Service (NWS) NEXRAD WSR-88D Doppler stations including **KNWS** (Idaho Regional Radar in Idaho). These high-frequency microwave radar sites transmit pulsed radio beams every 4.5 to 10 minutes, generating real-time base reflectivity scans.
Active Station Callsigns
How to Read Rain Radar Scale
Indicates light rain or atmospheric drizzle that usually does not impede travel.
Represents steady, moderate rainfall. Roads may experience pooling and reduced visibility.
Indicates torrential downpours, severe convective thunderstorms, lightning, or potential hail cores.
Regional Climate & Atmospheric Context
Idaho experiences dynamic regional weather conditions, requiring active Doppler radar monitoring for live rainfall, thunderstorm activity, and seasonal precipitation trends. Using S-band dual-polarization technology, radar pulses measure raindrop diameter and ice density to distinguish between light drizzle, torrential downpours, and hail.
