NWS Radar Station Infrastructure (Wisconsin)

Radar surveillance across Wisconsin relies on National Weather Service (NWS) NEXRAD WSR-88D Doppler stations including **KNWS** (Wisconsin Regional Radar in Wisconsin). These high-frequency microwave radar sites transmit pulsed radio beams every 4.5 to 10 minutes, generating real-time base reflectivity scans.

How to Read Rain Radar Scale

Light (15–30 dBZ)Green / Light Blue

Indicates light rain or atmospheric drizzle that usually does not impede travel.

Moderate (35–45 dBZ)Yellow / Orange

Represents steady, moderate rainfall. Roads may experience pooling and reduced visibility.

Heavy / Severe (50+ dBZ)Red / Purple / Pink

Indicates torrential downpours, severe convective thunderstorms, lightning, or potential hail cores.

Regional Climate & Atmospheric Context

Wisconsin 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.
