What you are usually seeing is called virga, or snow that sublimates into vapor before reaching the ground. Radar has to be pointed at a slight angle upward, which means the further the radar beam is from the source, the further up in the sky it is sampling. If you are 200 miles from the radar site, the radar beam is looking at least several thousand feet up in the sky, and light snow often won't reach the ground if the atmosphere is too dry.
Sometimes, but not always.
Typically it begins to snow in mid- to late-October. The snow lasts until late-March, sometimes into April.
You don't. Weather is based on what mother nature brings. Sometimes if you do the snow dance it will snow. But usually not. Sources: Mr.Kushner; UM
The answer is mountains.
It soon then becomes powdered snow and sometimes makes sleet or hailstones too.
Radar is used to detect concentrations of water droplets in the atmosphere, which tells meteorologists where rainfall, snow and hail are occurring.
A weather radar is a type of radar used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity.
Tornadoes can be very small, sometimes too small to be detected by Doppler radar, especially at long distances. The farther away from the radar a storm is, the less detail you can make out and the less you are able to see close to the ground.

I doubt it - there's no rain on the RADAR, and it's going to be fairly mild.
Sometimes it can cause snowfalls and you can get stuck in one but sometimes snow can help like if you drive a snow plow and get paid for it.
because microwaves both and radar systems both use microwaves
An avalanche is sometimes defined as a cascade of snow.
The difference in texture is really based on when you are feeling the snow. Right after a snowfall, the snow is fluffy. Then the snow hardens.

When someone says a guy is under the radar that usually means they think you're gay. They usually say "gaydar".
