Meteorologist Michelle Boss KREM

Sharing this radar loop to show you a cool phenomenon called "bright banding". Weather radars emit energy which is reflected back when it encounters precipitation. Snow is less reflective than rain. Since rain returns more energy, it will show up as comparatively stronger colors (yellows, orange...) than the snow (usually blues and greens) in a radar image. About an hour before the time of this loop, the Spokane Airport was reporting snow. Seeing the bright yellow showing up in this loop clued me in that that snow was melting and going over to rain. Just to the north of Spokane, however, snow was still falling. Of course if temperatures were warmer across the entire region, the different colors could just mean the difference between light rain and heavy rain. But in this scenario, seeing this "bright banding" helped me to see where the rain/snow line was.11 months ago
