The Weather

It was cloudy in Boulder, Colorado today. South of Denver had some larger storms. Below is the radar base reflectivity and the radar velocity. A gusty outflow boundary is visible on both maps.

Base reflectivity measures the presence of particles such as precipitation and dust (and sometimes even birds and bugs). 

Velocity measures the speed of the particles relative to the Doppler's location. Orange colors indicate particles moving away from the radar, and greens indicate particles moving toward the radar.

Meanwhile, the Wasatch Front is experiencing some hot weather and scattered thunderstorms. The MesoWest observations on the left show today's high temperatures. The radar image on the right shows thunderstorms near Ogden. (Click the images to make them bigger.)
